In 1901, {{age|1880|12|29|1901|7|20}}-year-old [[William S. Harley]] drew up plans for a small engine with a [[Engine displacement|displacement]] of 7.07 cubic inches (116&nbsp;cc) and four-inch (102&nbsp;mm) [[flywheel]]s<ref>{{Cite book |url=https://books.google.com/books?id=DreHM9-kvckC&pg=PA13 |page=13 |title=Classic Harley-Davidson, 1903–1941 |first=Herbert |last=Wagner |publisher=MotorBooks International |year=1999 |isbn=978-0-7603-0557-7 |access-date=November 19, 2015 |archive-date=January 1, 2014 |archive-url=https://web.archive.org/web/20140101145956/http://books.google.com/books?id=DreHM9-kvckC&pg=PA13 |url-status=live }}</ref><ref>{{Cite web |url=https://www.harley-davidson.com/us/en/museum/explore/hd-timeline.html |title=Harley-Davidson History Timeline |publisher=Harley-Davidson USA |access-date=November 2, 2018 |archive-date=August 29, 2019 |archive-url=https://web.archive.org/web/20190829123643/https://www.harley-davidson.com/us/en/museum/explore/hd-timeline.html |url-status=live }}</ref> designed for use in a regular pedal-bicycle frame. Over the next two years, he and his childhood friend [[Arthur Davidson (motorcycling)|Arthur Davidson]] worked on their [[Motorized bicycle|motor-bicycle]] using the northside [[Milwaukee]] machine shop at the home of their friend Henry Melk. It was finished in 1903 with the help of Arthur's brother Walter Davidson. Upon testing their power-cycle, Harley and the Davidson brothers found it unable to climb the hills around Milwaukee without pedal assistance, and they wrote off their first motor-bicycle as a valuable learning experiment.<ref>Herbert Wagner, 2003. ''At the Creation: Myth, Reality, and the Origin of the Harley-Davidson Motorcycle, 1901–1909'' (Madison: [[Wisconsin Historical Society Press]]), pp. 22–28, 42–44.</ref>

The three began work on a new and improved machine with an engine of 24.74 cubic inches (405&nbsp;cc) with {{convert|9.75|in|cm|abbr=on}} flywheels weighing {{convert|28|lb|kg|abbr=on}}. Its advanced loop-frame pattern was similar to the 1903 Milwaukee Merkel motorcycle designed by Joseph Merkel, later of [[Flying Merkel]] fame. The bigger engine and loop-frame design took it out of the motorized bicycle category and marked the path to future motorcycle designs. They also received help with their bigger engine from outboard motor pioneer [[Ole Evinrude]], who was then building gas engines of his own design for automotive use on Milwaukee's Lake Street.

[[File:Harley-Davidson Monocylinder.jpg|thumb|Prototype]]
The prototype of the new loop-frame Harley-Davidson was assembled in a {{convert|10|x|15|ft|m|abbr=on}} shed in the Davidson family backyard.<ref name="Wagner, 2003. pp.45–62">Wagner, 2003. pp. 45–62.</ref><ref>{{cite news|url=https://www.newspapers.com/image/2711470|title=King celebrating 95 impressive years|publisher=Kokomo Tribune {{subscription required|via=Newspapers.com}}|date=June 3, 1998|page=19|access-date=March 19, 2015|archive-date=April 2, 2015|archive-url=https://web.archive.org/web/20150402190954/http://www.newspapers.com/image/2711470/|url-status=live}}</ref> Most of the major parts, however, were made elsewhere, including some probably fabricated at the West Milwaukee railshops where oldest brother William A. Davidson was toolroom foreman. This prototype machine was functional by September 8, 1904, when it competed in a Milwaukee motorcycle race held at State Fair Park. Edward Hildebrand rode it and placed fourth in the race.<ref name="Wagner, 2003. pp.45–62" />

In January 1905, the company placed small advertisements in the ''Automobile and Cycle Trade Journal'' offering bare Harley-Davidson engines to the do-it-yourself trade. By April, they were producing complete motorcycles on a very limited basis. That year, Harley-Davidson dealer Carl H. Lang of Chicago sold three bikes from the five built in the Davidson backyard shed. Years later, the company moved the original shed to the Juneau Avenue factory where it stood for many decades as a tribute.

In 1906, Harley and the Davidson brothers built their first factory on Chestnut Street (later Juneau Avenue),<ref name="H-D timeline 1900s">{{cite web |url=http://www.harley-davidson.com/wcm/Content/Pages/H-D_History/history_1900s.jsp |title=HarleyDavidson History Timeline |publisher=Harley-Davidson Motorcycle Company |access-date=September 29, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120714065520/http://www.harley-davidson.com/wcm/Content/Pages/H-D_History/history_1900s.jsp |archive-date=July 14, 2012}}</ref> at the current location of Harley-Davidson's corporate headquarters.<ref name="employees"/> The first Juneau Avenue plant was a {{convert|40|x|60|ft|m|abbr=on}} single-story wooden structure. The company produced about 50 motorcycles that year.

[[File:Harley-Davidson 1000 cc HT 1916.jpg|thumb|left|Harley-Davidson 1,000&nbsp;cc HT 1916]]
In 1907, William S. Harley graduated from the [[University of Wisconsin–Madison]] with a degree in mechanical engineering. That year, they expanded the factory with a second floor and later with facings and additions of Milwaukee pale yellow ("cream") brick. With the new facilities, production increased to 150 motorcycles in 1907. The company was officially incorporated that September. They also began selling their motorcycles to police departments around this time, a market that has been important to them ever since.<ref>Wagner, 2003. pp. 68–81, 118.</ref> In 1907, William A. Davidson quit his job as tool foreman for the Milwaukee Road railroad and joined the Motor Company.

Production in 1905 and 1906 were all single-cylinder models with 26.84-cubic-inch (440&nbsp;cc) engines. In February 1907, they displayed a prototype model at the [[Chicago Auto Show|Chicago Automobile Show]] with a 45-degree [[V-Twin]] engine. Very few V-Twin models were built between 1907 and 1910. These first V-Twins displaced 53.68 cubic inches (880&nbsp;cc) and produced about {{convert|7|hp|kW}}. This gave about double the power of the first singles, and top speed was about {{convert|60|mph|km/h|-1|abbr=on}}. Production jumped from 450 motorcycles in 1908 to 1,149 machines in 1909.<ref>Wagner, 2003. pp. 124–25.</ref>

[[File:Harley Davidson Motor Company The Implement Age v16.jpg|thumb|Harley-Davidson works in 1911]]

In 1911, the company introduced an improved V-Twin model with a displacement of 49.48 cubic inches (811&nbsp;cc) and mechanically operated intake valves, as opposed to the "automatic" intake valves used on earlier V-Twins that opened by engine vacuum. It was smaller than earlier twins but gave better performance. After 1913, the majority of bikes produced by Harley-Davidson were V-Twin models.

In 1912, Harley-Davidson introduced their patented "Ful-Floteing Seat", which was suspended by a coil spring inside the seat tube.<ref>{{Cite book |last=Gingerelli |first=Dain |title=Harley-Davidson Museum Masterpieces |page=21 |chapter=1912 Model X–8–A |publisher=Motorbooks |location=Minneapolis, Minn. |year=2010 |url={{Google books |1c-d1dqD8DYC |Harley-Davidson Museum Masterpieces |plainurl=yes}} |chapter-url={{Google books |1c-d1dqD8DYC |Harley-Davidson Museum Masterpieces |page=20 |plainurl=yes}} |isbn=978-0-7603-3894-0 |lccn=2010014130}}</ref> The spring tension could be adjusted to suit the rider's weight, and more than {{Convert|3|in|mm}} of travel was available.<ref>{{Cite magazine |last=Plueddeman |first=Charles |title=Soul Survivor|magazine=[[Cycle World]] |date=July 1998 |volume=37 |issue=7 |page=73 |url={{Google books |dzSElH5E4AQC |Cycle World Magazine Jan 1998 |page=RA7-PA65 |plainurl=yes}} |editor-last=Edwards |editor-first=David |publisher=Hachette Filipacchi Magazines |location=Newport Beach, Calif. |issn=0011-4286}}</ref> Harley-Davidson used seats of this type until 1958.<ref>{{Cite book |last1=Gingerelli |first1=Dain |last2=Michels |first2=James Manning |last3=Everitt |first3=Charles |year=2010 |title=365 Motorcycles You Must Ride |page=91 |publisher=MBI Publishing |location=Minneapolis, Minn. |url={{Google books |Kabox9JS1OEC |title=365 Motorcycles You Must Ride |page=91 |plainurl=yes}} |isbn=978-0-7603-3474-4}}</ref>

By 1913, the yellow brick factory had been demolished and a new five-story structure had been built on the site which took up two blocks along Juneau Avenue and around the corner on 38th Street. Despite the competition, Harley-Davidson was already pulling ahead of [[Indian (motorcycle)|Indian]] and dominated motorcycle racing after 1914. Production that year swelled to 16,284 machines.

Harley-Davidson launched a line of bicycles in 1917 in hopes of recruiting more domestic customers for its motorcycles. Models included the traditional [[diamond frame]] men's bicycle, a [[step-through frame]] 3–18 "Ladies Standard", and a 5–17 "Boy Scout" for youth. The effort was discontinued in 1923 because of disappointing sales.<ref>Harley-Davidson Museum, Milwaukee, Wisconsin, various artifacts, ephemera, and placards. One placard states "''Harley-Davidson began as a motorcycle manufacturer unlike competitors such as Indian and Pope, which has [''sic''] previous histories in bicycling prior to building motorcycles. The many connections between bicycling and motorcycling prompted Harley-Davidson to begin selling bicycles in 1917. Despite heavy promotion, sales were disappointing and production was discontinued in 1923.''"</ref> The bicycles were built for Harley-Davidson in [[Dayton, Ohio|Dayton]], Ohio by the Davis Machine Company from 1917 to 1921, when Davis stopped manufacturing bicycles.<ref name="HeroBicycle">{{cite book |last=Youngblood |first=Ed |year=2003 |title=The Heroes of Harley-Davidson|url={{Google books|EsYzQ5W3d2sC|The Heroes of Harley-Davidson |page=137 |plainurl=yes}} |location=St. Paul, Minn. |publisher=Motorbooks International |page=137 |isbn=0-7603-1595-7 |access-date=April 19, 2014}}</ref>

Harley-Davidson, on the eve of World War II, was already supplying the Army with a military-specific version of its {{convert|45|cuin}} WL line, called the [[Harley-Davidson WLA|WLA]]. The A in this case stood for "Army". Upon the outbreak of war, the company, along with most other manufacturing enterprises, shifted to war work. Some 90,000 military motorcycles, mostly WLAs and WLCs (the Canadian version) were produced, many to be provided to allies.<ref name="wildthing">''[[Smithsonian (magazine)|Smithsonian]]'' magazine, August 2003, pp. 34 – "Wild Thing", Robert F.

Production of the WLA stopped at the end of World War II, but was resumed from 1949 to 1952 for use in the [[Korean War]].

The U.S. Army also asked Harley-Davidson to produce a new motorcycle with many of the features of [[History of BMW motorcycles|BMW's]] side-valve and [[Drive shaft|shaft-driven]] R71. Harley-Davidson largely copied the BMW engine and drive train and produced the shaft-driven 750&nbsp;cc 1942 and '43 [[Harley-Davidson XA]]. This shared no dimensions, no parts or no design concepts (except side valves) with any prior Harley-Davidson engine. Due to the superior cooling of the [[flat-twin]] engine with the cylinders across the frame, Harley's XA cylinder heads ran 100&nbsp;°F (56&nbsp;°C) cooler than its V-twins.<!-- The conversion template from °F to °C is a conversion of temperature values, and does not work for temperature differences.

Harley-Davidson replaced their American-made lightweight two-stroke motorcycles with the Italian [[Aermacchi]]-built two-stroke powered M-65, M-65S, and Rapido. The M-65 had a semi-step-through frame and tank. The M-65S was a M-65 with a larger tank that eliminated the step-through feature.

Harley-Davidson purchased full control of [[Aermacchi]]'s motorcycle production in 1974 and continued making two-stroke motorcycles there until 1978, when they sold the facility to [[Cagiva]], owned by the Castiglioni family.<ref name="EncycMoto 252" />

Revising stagnated product designs was a crucial centerpiece of Harley-Davidson's turnaround strategy. Rather than trying to mimic popular Japanese designs, the new management deliberately exploited the "retro" appeal of Harley motorcycles, building machines that deliberately adopted the look and feel of their earlier bikes and the subsequent customizations of owners of that era. Many components such as brakes, forks, shocks, carburetors, electrics and wheels were outsourced from foreign manufacturers and quality increased, technical improvements were made, and buyers slowly returned.

Harley-Davidson bought the "Sub Shock" cantilever-swingarm rear suspension design from Missouri engineer Bill Davis and developed it into its [[Softail]] series of motorcycles, introduced in 1984 with the FXST Softail.<ref name="HDCentury_FatherSoftail">{{cite encyclopedia|last=Field|first=Greg|editor=Darwin Holmstrom|encyclopedia=The Harley-Davidson Century|title=Father of the Softail|url=https://books.google.com/books?id=kUidavBaEbUC|access-date=December 26, 2012|date=September 1, 2002|publisher=MotorBooks International|location=St. Paul, Minn.|isbn=0-7603-1155-2|pages=242–243}}{{Dead link|date=November 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

Harley-Davidson's association with [[sport bike|sportbike]] manufacturer [[Buell Motorcycle Company]] began in 1987 when they supplied Buell with fifty surplus XR1000 engines.

===Claims of stock price manipulation===
[[File:HOG 5years.PNG|frame|Harley-Davidson, Inc. (NYSE:HOG) stock price (source: ZenoBank.com)]]
During its period of peak demand, during the late 1990s and early first decade of the 21st century, Harley-Davidson embarked on a program of expanding the number of dealerships throughout the country{{which|date=August 2024}}. At the same time, its current dealers typically had waiting lists that extended up to a year for some of the most popular models. Harley-Davidson, like the auto manufacturers, records a sale not when a consumer buys their product, but rather when it is delivered to a dealer. Therefore, it is possible for the manufacturer to inflate sales numbers by requiring dealers to accept more inventory than desired in a practice called [[channel stuffing]]. When demand softened following the unique{{why|date=August 2024}} 2003 model year, this news led to a dramatic decline in the stock price. In April 2004 alone, the price of HOG shares dropped from more than $60 to less than $40. Immediately prior to this decline, retiring CEO Jeffrey Bleustein profited $42&nbsp;million on the exercise of [[employee stock option]]s.<ref>{{cite web |url=https://www.sec.gov/Archives/edgar/data/793952/000122520804000684/xslF345X02/doc4.xml |title=SEC Form 4 |website=sec.gov |date=April 15, 2004 |publisher=US Securities and Exchange Commission |access-date=August 29, 2017 |archive-date=July 10, 2017 |archive-url=https://web.archive.org/web/20170710051225/https://www.sec.gov/Archives/edgar/data/793952/000122520804000684/xslF345X02/doc4.xml |url-status=live }}</ref> Harley-Davidson was named as a defendant in numerous [[class action]] suits filed by investors who claimed they were intentionally defrauded by Harley-Davidson's management and directors.<ref>{{cite web |url=http://www.glancylaw.com/amazing_case.php?caseid=125 |title=Glancy Binkow & Goldberg LLP – Attorneys at Law |website=Glancylaw.com |date=January 21, 2004 |access-date=January 5, 2009 |url-status=dead |archive-date=June 21, 2008 |archive-url=https://web.archive.org/web/20080621221725/http://www.glancylaw.com/amazing_case.php?caseid=125}}</ref> By January 2007, the price of Harley-Davidson shares reached $70.

===2008 financial crisis===
The [[2008 financial crisis]] and [[2008–2010 automotive industry crisis]] affected also the motorcycle industry. According to Interbrand, the value of the Harley-Davidson brand fell by 43 percent to $4.34&nbsp;billion in 2009. The fall in value is believed to be connected to the 66 percent drop in the company profits in two-quarters of the previous year.<ref>{{cite web |url=http://english.pravda.ru/business/companies/23-09-2009/109454-harley_davidson-0 |title=Harley-Davidson, Toyota and Porsche Brands Lose Value |access-date=October 1, 2009 |date=September 21, 2009 |publisher=Pravda.ru |archive-date=September 26, 2009 |archive-url=https://web.archive.org/web/20090926074555/http://english.pravda.ru/business/companies/23-09-2009/109454-harley_davidson-0 |url-status=live }}</ref> On April 29, 2010, Harley-Davidson stated that they must cut $54&nbsp;million in manufacturing costs from its production facilities in Wisconsin, and that they would explore alternative U.S. sites to accomplish this.

==Motorcycle engines==
[[File:Harley Davidson.jpg|thumb|upright|{{convert|1450|cc}} V-twin]]
{{Main|Harley-Davidson engine timeline}}

The classic Harley-Davidson engines are [[V-twin engine]]s, with a 45° angle between the cylinders. The [[crankshaft]] has a single pin, and both [[piston]]s are connected to this pin through their [[connecting rod]]s.<ref name="wfwvmg" />

This 45° angle is covered under several [[United States Patent and Trademark Office|United States patents]] and is an engineering tradeoff that allows a large, high-torque engine in a relatively small space. It causes the cylinders to fire at uneven intervals and produces the choppy "potato-potato" sound so strongly linked to the Harley-Davidson brand.

To simplify the engine and reduce costs, the V-twin ignition was designed to operate with a single set of points and no distributor. This is known as a dual fire ignition system, causing both spark plugs to fire regardless of which cylinder was on its compression stroke, with the other spark plug firing on its cylinder's exhaust stroke, effectively "[[wasted spark|wasting a spark]]". The exhaust note is basically a throaty growling sound with some popping.
The 45° design of the engine thus creates a plug firing sequencing as such: The first cylinder fires, the second (rear) cylinder fires 315° later, then there is a 405° gap until the first cylinder fires again, giving the engine its unique sound.<ref>{{cite web|url=http://auto.howstuffworks.com/harley3.htm|title=Howstuffworks 'The Harley Sound and Mystique'|work=auto.howstuffworks.com|date=September 17, 2003|access-date=April 27, 2008|archive-date=February 23, 2008|archive-url=https://web.archive.org/web/20080223115625/http://auto.howstuffworks.com/harley3.htm|url-status=live}}</ref>

Harley-Davidson has used various ignition systems, including the early points and condenser system on Big Twins and Sportsters up to 1978, a magneto ignition system used on some 1958 to 1969 Sportsters, an early electronic with centrifugal mechanical advance weights on all models from mid-1978 until 1979, and a later electronic with a transistorized ignition control module (more familiarly known as a black box or a brain) on all models 1980 to present.

Starting in 1995, the company introduced Electronic Fuel Injection (EFI) as an option for the 30th anniversary edition [[Electra Glide]].<ref name="H-D timeline 1990s">{{cite web|url=http://www.harley-davidson.com/wcm/Content/Pages/H-D_History/history_1990s.jsp?locale=en_US |title=HarleyDavidson – Timeline 1990's|work=harley-davidson.com|access-date=April 27, 2008|archive-date=October 3, 2008|archive-url=https://web.archive.org/web/20081003125510/http://www.harley-davidson.com/wcm/Content/Pages/H-D_History/history_1990s.jsp?locale=en_US|url-status=dead}}</ref> EFI became standard on all Harley-Davidson motorcycles, including Sportsters, upon the introduction of the 2007 product line.<ref>{{cite web|url=http://www.nightrider.com/biketech/motorcycle_efi_basics.htm|title=Harley-Davidson Motorcycle Fuel Injection Explained|work=nightrider.com|access-date=April 27, 2008|archive-date=October 7, 2018|archive-url=https://web.archive.org/web/20181007143229/http://www.nightrider.com/biketech/motorcycle_efi_basics.htm|url-status=live}}</ref>

In 1991, Harley-Davidson began to participate in the Sound Quality Working Group, founded by Orfield Labs, Bruel and Kjaer, [[TEAC Corporation|TEAC]], [[Yamaha Motor Company|Yamaha]], [[Sennheiser]], SMS and Cortex. This was the nation's first group to share research on psychological acoustics. Later that year, Harley-Davidson participated in a series of sound quality studies at Orfield Labs, based on recordings taken at the [[Talladega Superspeedway]], with the objective to lower the sound level for EU standards while analytically capturing the "Harley Sound".<ref>{{Cite web |title=Products {{!}} Orfield Laboratories Inc |url=https://www.orfieldlabs.com/products |access-date=2022-07-22 |website=www.orfieldlabs.com}}</ref><ref>{{Cite journal |last1=PIerson |first1=Richard G. |last2=Bozmoski |first2=Alexander J. |date=2003 |title=Harley-Davidson's 100th anniversary: The sound of a legend |url=https://www.semanticscholar.org/paper/Harley-Davidson's-100th-anniversary%253A-The-sound-of-a-Pierson-Bozmoski/ |journal=Sound and Vibration |volume=37 |pages=14–17 |via=Semantic Scholar}}</ref> This research resulted in the bikes that were introduced in compliance with EU standards for 1998.

On February 1, 1994, the company filed a [[sound trademark]] application for the distinctive sound of the Harley-Davidson motorcycle engine: "The mark consists of the exhaust sound of applicant's motorcycles, produced by V-twin, common crankpin motorcycle engines when the goods are in use". Nine of Harley-Davidson's competitors filed comments opposing the application, arguing that cruiser-style motorcycles of various brands use a single-crankpin V-twin engine which produce a similar sound.<ref>{{cite web|url=http://www.bc.edu/bc_org/avp/law/st_org/iptf/articles/content/1998101101.html|title=The Trademark Registrability of the Harley-Davidson Roar: A Multimedia Analysis|work=bc.edu|access-date=April 27, 2008|archive-url=https://web.archive.org/web/20100604001508/http://www.bc.edu/bc_org/avp/law/st_org/iptf/articles/content/1998101101.html|archive-date=June 4, 2010|url-status=dead}}</ref> These objections were followed by litigation.

====Düsseldorf-Test====
An extreme endurance test of the Revolution engine was performed in a dynamometer installation at the Harley-Davidson factory in Milwaukee, simulating the German [[Autobahn]] (highways without general speed limit) between the Porsche research and development center in Weissach, near Stuttgart to [[Düsseldorf]]. An undisclosed number of samples of engines failed, until an engine successfully passed the 500-hour nonstop run.

==Model families==
Modern Harley-branded motorcycles fall into one of seven model families: Touring, Softail, Dyna, Sportster, Vrod, Street and LiveWire. These model families are distinguished by the frame, engine, suspension, and other characteristics.

===Touring===
{{See also|Harley-Davidson FL}}
[[File:Harley-Davidson Road King in Switzerland (2022).jpg|thumb|Harley-Davidson Road King]]
[[File:PolizeiHarley.JPG|thumb|Hamburg Police [[Harley-Davidson FL#Electra-Glide|Electra Glide]]]]
Touring models use Big-Twin engines and large-diameter telescopic forks. All Touring designations begin with the letters FL, ''e.g.'', FLHR (Road King) and FLTR (Road Glide).

The touring family, also known as "dressers" or "baggers", includes Road King, Road Glide, Electra Glide and Street Glide models offered in various trims. The Road Kings have a "retro cruiser" appearance and are equipped with a large clear windshield. Road Kings are reminiscent of big-twin models from the 1940s and 1950s. Electra Glides can be identified by their full front fairings. Most Electra Glides sport a fork-mounted fairing referred to as the "Batwing" due to its unmistakable shape. The Road Glide and Road Glide Ultra Classic have a frame-mounted fairing, referred to as the "Sharknose". The Sharknose includes a unique, dual front headlight.

Touring models are distinguishable by their large saddlebags, rear coil-over air suspension and are the only models to offer full fairings with radios and [[Citizens Band radio|CBs]]. All touring models use the same frame, first introduced with a Shovelhead motor in 1980, and carried forward with only modest upgrades until 2009, when it was extensively redesigned. The frame is distinguished by the location of the steering head in front of the forks and was the first H-D frame to rubber mount the drivetrain to isolate the rider from the vibration of the big V-twin.
[[File:harley.electraglide.750pix.jpg|thumb|Electra Glide "Ultra Classic"]]
The frame was modified for the 1993 model year when the oil tank went under the transmission and the battery was moved inboard from under the right saddlebag to under the seat. In 1997, the frame was again modified to allow for a larger battery under the seat and to lower seat height.

In 2006, Harley introduced the FLHX Street Glide, a bike designed by Willie G. Davidson to be his personal ride, to its touring line.<ref>{{cite web|url=http://www.brainbucketmag.com/News/article/sid=408.html|archive-url=https://web.archive.org/web/20070929090553/http://www.brainbucketmag.com/News/article/sid=408.html|url-status=dead|archive-date=September 29, 2007 |last=Newbern |first=Michael |title=First Ride: 2007 FLHX |date=August 8, 2006}}</ref>

In 2008, Harley added [[anti-lock braking system]]s and cruise control as a factory installed option on all touring models (standard on CVO and Anniversary models).<ref name="ABS">{{Cite press release |title=ABS Option on All Harley-davidson Touring and VRSC Models |publisher=Harley-Davidson |date=July 9, 2007 |url=http://www.harley-davidson.com/CO/NEW/en/PressRelease_date.asp?locale=en_US&bmLocale=en_US&HDCWPSession=vHLgG6cQLh81Jl9BDmTDST1frXYC02vTcXyzfQGn090yRDvTJyQb!-1996869500!400212047&id_in=1244&dspmm=7&dspyy=2007&FROM=NewsARCHIVE |access-date=September 26, 2007 |url-status=dead |archive-url=https://web.archive.org/web/20080220062801/http://www.harley-davidson.com/CO/NEW/en/PressRelease_date.asp?locale=en_US&bmLocale=en_US&HDCWPSession=vHLgG6cQLh81Jl9BDmTDST1frXYC02vTcXyzfQGn090yRDvTJyQb!-1996869500!400212047&id_in=1244&dspmm=7&dspyy=2007&FROM=NewsARCHIVE |archive-date=February 20, 2008}}</ref> Also new for 2008 is the {{convert|6|usgal|adj=on}} fuel tank for all touring models. 2008 also brought throttle-by-wire to all touring models.

===Softail===
{{Main|Softail}}

[[File:Evb-my hog.jpg|thumb|2002 [[Softail]] Heritage Classic]]
These big-twin motorcycles capitalize on Harley's strong value on tradition. With the rear-wheel suspension hidden under the transmission, they are visually similar to the "hardtail" [[Chopper (motorcycle)|choppers]] popular in the 1960s and 1970s, as well as from their own earlier history. In keeping with that tradition, Harley offers Softail models with "Heritage" styling that incorporate design cues from throughout their history and used to offer "Springer" front ends on these Softail models from the factory.

;Designation
Softail models utilize the big-twin engine (F) and the Softail chassis (ST).
* Softail models that use 21-inch (530&nbsp;mm) Front Wheels have designations that begin with FX, ''e.g.'', FXSTB (Night Train), FXSTD (Deuce), and FXSTS (Springer).
* Softail models that use 16-inch (410&nbsp;mm) Front Wheels have designations beginning with FL, ''e.g.'', FLSTF (Fat Boy), FLSTC (Heritage Softail Classic), FLSTN (Softail Deluxe) and FLS (Softail Slim).
* Softail models that use Springer forks with a {{convert|21|in|mm|adj=on}} wheel have designations that begin with FXSTS, ''e.g.'', FXSTS (Springer Softail) and FXSTSB (Bad Boy).
* Softail models that use Springer forks with a {{convert|16|in|mm|adj=on}} wheel have designations that begin with FLSTS, ''e.g.'', FLSTSC (Springer Classic) and FLSTSB (Cross Bones).

===Dyna===
{{Main|Harley-Davidson Super Glide}}
[[File:Harley-Davidson 18.jpg|thumb|2005 Dyna [[Harley-Davidson Super Glide|Super Glide]] Custom]]
Dyna-frame motorcycles were developed in the 1980s and early 1990s and debuted in the 1991 model year with the FXDB Sturgis offered in limited edition quantities. In 1992 the line continued with the limited edition FXDB Daytona and a production model FXD Super Glide. The new DYNA frame featured big-twin engines and traditional styling. They can be distinguished from the Softail by the traditional coil-over suspension that connects the swingarm to the frame, and from the Sportster by their larger engines. On these models, the transmission also houses the engine's oil reservoir.

Prior to 2006, Dyna models typically featured a narrow, XL-style 39mm front fork and front wheel, as well as footpegs which the manufacturer indicated with the letter "X" in the model designation. This lineup traditionally included the Super Glide (FXD), Super Glide Custom (FXDC), Street Bob (FXDB), and Low Rider (FXDL). One exception was the Wide Glide (FXDWG), which featured thicker 41mm forks and a narrow front wheel, but positioned the forks on wider triple-trees that give a beefier appearance. In 2008, the Dyna Fat Bob (FXDF) was introduced to the Dyna lineup, featuring aggressive styling like a new 2–1–2 exhaust, twin headlamps, a 180&nbsp;mm rear tire, and, for the first time in the Dyna lineup, a 130&nbsp;mm front tire. For the 2012 model year, the Dyna Switchback (FLD) became the first Dyna to break the tradition of having an FX model designation with floorboards, detachable painted hard saddlebags, touring windshield, headlight nacelle and a wide front tire with full fender.  The new front end resembled the big-twin FL models from 1968 to 1971.

The Dyna family used the 88-cubic-inch (1,440&nbsp;cc) twin cam from 1999 to 2006. In 2007, the displacement was increased to 96 cubic inches (1,570&nbsp;cc) as the factory increased the stroke to {{convert|4.375|in|mm|1}}. For the 2012 model year, the manufacturer began to offer Dyna models with the 103-cubic-inch (1,690&nbsp;cc) upgrade.  All Dyna models use a rubber-mounted engine to isolate engine vibration. Harley discontinued the Dyna platform in 2017 for the 2018 model year, having been replaced by a completely-redesigned [[Softail]] chassis; some of the existing models previously released by the company under the Dyna nameplate have since been carried over to the new Softail line.<ref name="First looks">{{cite magazine |url=http://www.cycleworld.com/2018-harley-davidson-softail-lineup// |title=2018 Harley-Davidson Softail Cruiser Lineup |magazine=[[Cycle World]] |access-date=August 24, 2017 |year=2017 |archive-date=August 23, 2017 |archive-url=https://web.archive.org/web/20170823214634/http://www.cycleworld.com/2018-harley-davidson-softail-lineup |url-status=live }}</ref>

;Designation
Dyna models utilize the big-twin engine (F), footpegs noted as (X) with the exception of the 2012 FLD Switchback, a Dyna model which used floorboards as featured on the Touring (L) models, and the Dyna chassis (D). Therefore, except for the FLD from 2012 to 2016, all Dyna models have designations that begin with FXD, ''e.g.'', FXDWG (Dyna Wide Glide) and FXDL (Dyna Low Rider).

===Sportster===
{{Main|Harley-Davidson Sportster}}

[[File:2003 HD XL1200C Anniversary Edition.jpg|thumb|2003 Harley-Davidson XL1200 Custom Anniversary Edition
]]
Introduced in 1957, the Sportster family were conceived as racing motorcycles, and were popular on dirt and flat-track race courses through the 1960s and 1970s. Smaller and lighter than the other Harley models, contemporary Sportsters make use of 883&nbsp;cc or 1,200&nbsp;cc Evolution engines and, though often modified, remain similar in appearance to their racing ancestors.<ref>{{cite web|url=http://www.motorcycleclassics.com/motorcycle-reviews/harley-davidson-sportster-1000.aspx|title=1972–1985 Harley-Davidson Sportster 1000|publisher=Motorcycle Classics|access-date=May 21, 2010|date=March–April 2010|author=Richard Backus|archive-date=May 22, 2010|archive-url=https://web.archive.org/web/20100522134006/http://www.motorcycleclassics.com/motorcycle-reviews/harley-davidson-sportster-1000.aspx|url-status=live}}</ref>

Up until the 2003 model year, the engine on the Sportster was rigidly mounted to the frame. The 2004 Sportster received a new frame accommodating a rubber-mounted engine. This made the bike heavier and reduced the available lean angle, while it reduced the amount of vibration transmitted to the frame and the rider, providing a smoother ride for rider and passenger.<ref>[http://www.motorcyclecruiser.com/roadtests/2004_harley_davidson_sportster/ ''Motorcycle Cruiser'' First Ride: 2004 Harley-Davidson Sportster Motorcycles] {{Webarchive|url=https://web.archive.org/web/20081201115222/http://www.motorcyclecruiser.com/roadtests/2004_harley_davidson_sportster/ |date=December 1, 2008 }}.

In the 2007 model year, Harley-Davidson celebrated the 50th anniversary of the Sportster and produced a limited edition called the XL50, of which only 2000 were made for sale worldwide. Each motorcycle was individually numbered and came in one of two colors, Mirage Pearl Orange or Vivid Black. Also in 2007, electronic fuel injection was introduced to the Sportster family, and the Nightster model was introduced in mid-year. In 2009, Harley-Davidson added the Iron 883 to the Sportster line, as part of the Dark Custom series.
In the 2008 model year, Harley-Davidson released the XR1200 Sportster in Europe, Africa, and the Middle East. The XR1200 had an Evolution engine tuned to produce {{convert|91|bhp|abbr=on}}, four-piston dual front disc brakes, and an aluminum swing arm.  ''[[Motorcyclist (magazine)|Motorcyclist]]'' featured the XR1200 on the cover of its July 2008 issue and was generally positive about it in their "First Ride" story, in which Harley-Davidson was repeatedly asked to sell it in the United States.<ref>{{Cite magazine |last=Cathcart |first=Alan |date=July 2008 |title=First Ride: 2008 Harley-Davidson XR1200 – Get Sporty!|magazine=[[Motorcyclist (magazine)|Motorcyclist]]|pages=49–53|publisher=Source Interlink Magazines}}</ref>
One possible reason for the delayed availability in the United States was that Harley-Davidson had to obtain the "XR1200" naming rights from Storz Performance, a Harley customizing shop in Ventura, Calif.<ref>{{cite web|url=http://www.motorcycleclassics.com/motorcycle-reviews/2009-harley-davidson-xr1200.aspx|title=2009 Harley-Davidson XR1200|publisher=Motorcycle Classics|access-date=August 20, 2009|date=September–October 2009|author=Richard Backus|archive-date=October 20, 2009|archive-url=https://web.archive.org/web/20091020111135/http://www.motorcycleclassics.com/motorcycle-reviews/2009-harley-davidson-xr1200.aspx|url-status=live}}</ref> The XR1200 was released in the United States in 2009 in a special color scheme including Mirage Orange highlighting its dirt-tracker heritage. The first 750 XR1200 models in 2009 were pre-ordered and came with a number 1 tag for the front of the bike, autographed by [[Kenny Coolbeth]] and [[Scott Parker (motorcyclist)|Scott Parker]] and a thank you/welcome letter from the company, signed by Bill Davidson.{{Citation needed |date=July 2009}} The XR1200 was discontinued in model year 2013.

In 2021, Harley-Davidson launched the Sportster S model, with a 121&nbsp;hp engine and 228 Kg ready-to-ride weight.<ref>{{Cite web|url=https://www.harley-davidson.com/gb/en/motorcycles/sportster-s.html|title=2022 Sportster S &#124; Harley-Davidson United Kingdom|website=Harley-Davidson|access-date=July 20, 2021|archive-date=July 20, 2021|archive-url=https://web.archive.org/web/20210720095312/https://www.harley-davidson.com/gb/en/motorcycles/sportster-s.html|url-status=live}}</ref> The Sportster S was one of the first Harleys to come with cornering-ABS and lean-sensitive traction control.<ref>{{Cite web|url=https://www.motorcyclenews.com/news/new-bikes/harley-davidson-sportster-s/|title=Harley-Davidson Sportster S unveiled with new chassis, new engine and new £14k pricetag|access-date=July 20, 2021|archive-date=July 20, 2021|archive-url=https://web.archive.org/web/20210720095309/https://www.motorcyclenews.com/news/new-bikes/harley-davidson-sportster-s/|url-status=live}}</ref> The Sportster S is also the first model under the Sportster nameplate since 1957 to receive a completely new engine.

;Designation
Except for the street-going XR1000 of the 1980s and the XR1200, most Sportsters made for street use have the prefix XL in their model designation. For the Sportster Evolution engines used since the mid-1980s, there have been two engine sizes. Motorcycles with the smaller engine are designated XL883, while those with the larger engine were initially designated XL1100. When the size of the larger engine was increased from 1,100&nbsp;cc to 1,200&nbsp;cc, the designation was changed accordingly from XL1100 to XL1200. Subsequent letters in the designation refer to model variations within the Sportster range, e.g. the XL883C refers to an 883&nbsp;cc Sportster Custom, while the XL1200S designates the now-discontinued 1200 Sportster Sport.

===VRSC===
{{Main|Harley-Davidson VRSC}}
[[File:Harley 5-06.jpg|thumb|2003 VRSCA V-Rod]]
Introduced in 2001 and produced until 2017,<ref name="Last">{{Cite magazine |title=Smart Money Muscle Bikes |last=Smith |first=Jerry |magazine=[[Motorcyclist (magazine)|Motorcyclist]] |pages=106–107 |date=May–June 2017}}</ref> the VRSC muscle bike family bears little resemblance to Harley's more traditional lineup. Competing against Japanese and American muscle bikes in the upcoming [[power cruiser|muscle bike/power cruiser]] segment, the "V-Rod" makes use of the revolution engine that, for the first time in Harley history, incorporates [[overhead cam]]s and liquid cooling. The V-Rod is visually distinctive, easily identified by the 60-degree V-Twin engine, the radiator and the [[Hydroforming|hydroformed]] frame members that support the round-topped air cleaner cover. The VRSC [[Automobile platform|platform]] was also used for factory drag-racing motorcycles.

In 2008, Harley added the anti-lock braking system as a factory-installed option on all VRSC models.<ref name="ABS" /> Harley also increased the displacement of the stock engine from {{convert|1130|to|1250|cc|cuin|abbr=on}}, which had only previously been available from Screamin' Eagle, and added a slipper clutch as standard equipment.

VRSC models include:
* VRSCA: V-Rod (2002–2006), VRSCAW: V-Rod (2007–2010), VRSCB: V-Rod (2004–2005), VRSCD: Night Rod (2006–2008), VRSCDX: Night Rod Special (2007–2014), VRSCSE: Screamin' Eagle CVO V-Rod (2005), VRSCSE2: Screamin' Eagle CVO V-Rod (2006), VRSCR: Street Rod (2006–2007), VRSCX: Screamin' Eagle Tribute V-Rod (2007), VRSCF: V-Rod Muscle (2009–2014).
VRSC models utilize the Revolution engine (VR), and the street versions are designated Street Custom (SC). After the VRSC prefix common to all street Revolution bikes, the next letter denotes the model, either A (base V-Rod: discontinued), AW (base V-Rod + W for Wide with a 240&nbsp;mm rear tire), B (discontinued), D (Night Rod: discontinued), R (Street Rod: discontinued), SE and SEII (CVO Special Edition), or X (Special edition). Further differentiation within models are made with an additional letter, ''e.g.'', VRSCDX denotes the Night Rod Special.

====VRXSE====
The VRXSE V-Rod Destroyer is Harley-Davidson's production drag racing motorcycle, constructed to run the quarter mile in less than ten seconds. It is based on the same revolution engine that powers the VRSC line, but the VRXSE uses the Screamin' Eagle 1,300&nbsp;cc "stroked" incarnation, featuring a 75&nbsp;mm crankshaft, 105&nbsp;mm Pistons, and 58&nbsp;mm throttle bodies.

The V-Rod Destroyer is not a street-legal motorcycle. As such, it uses "X" instead of "SC" to denote a non-street bike.  "SE" denotes a CVO Special Edition.

===Street===

In March 2020, a Harley-Davidson LiveWire was used to break the 24-hour distance record for an electric motorcycle. The bike traveled a reported 1,723&nbsp;km (1,079 miles) in 23 hours and 48 minutes. The LiveWire offers a Level 1 slow recharge, which uses a regular wall outlet to refill an empty battery overnight, or a quick Level 3 DC Fast Charge.

Every year since 1999, the team has selected two to five of the company's base models and added higher-displacement engines, performance upgrades, special-edition paint jobs, more chromed or accented components, audio system upgrades, and electronic accessories to create high-dollar, premium-quality customizations for the [[custom motorcycle|factory custom]] market.<ref>{{Cite news |url=http://www.motorcycle-usa.com/2011/07/article/2012-harley-davidson-cvo-first-rides/ |title=2012 Harley-Davidson CVO First Rides |work=Motorcycle USA |access-date=February 12, 2018 |archive-date=January 17, 2018 |archive-url=https://web.archive.org/web/20180117131156/http://www.motorcycle-usa.com/2011/07/article/2012-harley-davidson-cvo-first-rides/ |url-status=live }}</ref> The models most commonly upgraded in such a fashion are the Ultra Classic Electra Glide, which has been selected for CVO treatment every year from 2006 to the present, and the Road King, which was selected in 2002, 2003, 2007, and 2008. The Dyna, Softail, and VRSC families have also been selected for CVO customization.

==Environmental record==
The [[United States Environmental Protection Agency|Environmental Protection Agency]] conducted emissions-certification and representative emissions test in [[Ann Arbor, Michigan]], in 2005. Subsequently, Harley-Davidson produced an "environmental warranty". The warranty ensures each owner that the vehicle is designed and built free of any defects in materials and workmanship that would cause the vehicle to not meet EPA standards.<ref>[http://epa.gov/otaq/regs/roadbike/21-harley-pres.pdf Representative Emissions Test] {{Webarchive|url=https://web.archive.org/web/20090127003227/http://epa.gov/otaq/regs/roadbike/21-harley-pres.pdf |date=January 27, 2009}} March 9, 2005. Retrieved May 14, 2008</ref> In 2005, the EPA and the [[Pennsylvania Department of Environmental Protection]] (PADEP) confirmed Harley-Davidson to be the first corporation to voluntarily enroll in the One Clean-Up Program. This program is designed for the clean-up of the affected soil and groundwater at the former York Naval Ordnance Plant. The program is backed by the state and local government along with participating organizations and corporations.<ref name="vupxae">[http://www.yorksiteremedy.com/ Former York Naval Ordnance Plant] {{Webarchive|url=https://web.archive.org/web/20101129044601/http://www.yorksiteremedy.com/ |date=November 29, 2010 }} 2005.

Paul Gotthold, Director of Operations for the EPA, congratulated the motor company:
{{blockquote|Harley-Davidson has taken their environmental responsibilities very seriously and has already made substantial progress in the investigation and cleanup of past contamination. Proof of Harley's efforts can be found in the recent EPA determination that designates the Harley property as 'under control' for cleanup purposes. This determination means that there are no serious contamination problems at the facility. Under the new One Cleanup Program, Harley, EPA, and PADEP will expedite the completion of the property investigation and reach a final solution that will permanently protect human health and the environment.<ref name="vupxae" />}}
Harley-Davidson also purchased most of Castalloy, a South Australian producer of cast motorcycle wheels and hubs. The South Australian government has set forth "protection to the purchaser (Harley-Davidson) against environmental risks".

In August 2016, Harley-Davidson settled with the EPA for $12&nbsp;million, without admitting wrongdoing, over the sale of [[aftermarket (automotive)|after-market]] "super tuners".<ref>{{cite web |last1=Geuss |first1=Megan |title=EPA punishes Harley-Davidson for selling an aftermarket tuner that elevated emissions |url=https://arstechnica.com/cars/2016/08/harley-davidson-to-pay-12-million-for-emissions-spewing-aftermarket-tuners/ |access-date=August 19, 2016 |website=Ars Technica |date=August 19, 2016 |archive-date=August 18, 2016 |archive-url=https://web.archive.org/web/20160818235952/http://arstechnica.com/cars/2016/08/harley-davidson-to-pay-12-million-for-emissions-spewing-aftermarket-tuners/ |url-status=live }}</ref><ref>{{cite news |last1=Eaton |first1=Sabrina |title=U.S. EPA fines Harley-Davidson for emissions violations caused by 'super tuners' |url=http://www.cleveland.com/metro/index.ssf/2016/08/epa_cracks_down_on_harley-davi.html |access-date=August 19, 2016 |work=The Plain Dealer |date=August 19, 2016 |archive-date=August 18, 2016 |archive-url=https://web.archive.org/web/20160818183214/http://www.cleveland.com/metro/index.ssf/2016/08/epa_cracks_down_on_harley-davi.html |url-status=live }}</ref> Super tuners were devices, marketed for competition, which enabled increased performance of Harley-Davidson products.

From its founding, Harley-Davidson had worked to brand its motorcycles as respectable and refined products, with ads that showed what motorcycling writer Fred Rau called "refined-looking ladies with parasols, and men in conservative suits as the target market".<ref name="Rau 2007" /><ref name="Rau 2008" /> The 1906 Harley-Davidson's effective, and polite, muffler was emphasized in advertisements with the nickname [[Harley-Davidson Model 7D|"The Silent Gray Fellow"]].<ref name="Rau 2008" /><ref name="Hook 2002" /> That began to shift in the 1960s, partially in response to the clean-cut motorcyclist portrayed in Honda's "[[You meet the nicest people on a Honda]]" campaign, when Harley-Davidson sought to draw a contrast with Honda by underscoring the more working-class, macho, and even a little anti-social attitude associated with motorcycling's dark side. With the 1971 [[Harley-Davidson Super Glide|FX Super Glide]], the company embraced, rather than distanced itself from, [[chopper (motorcycle)|chopper]] style and the counterculture custom Harley scene.<ref name="100 Years" /> Their marketing cultivated the "bad boy" image of [[Motorcycle#Social aspects|biker]] and [[motorcycle club]]s, and to a point, even [[outlaw motorcycle club|outlaw or one-percenter]] motorcycle clubs.<ref name="Rau 2007" /><ref name="Rau 2008" />

===Origin of "Hog" nickname===
Beginning in 1920, a team of farm boys, including [[Ray Weishaar]], who became known as the "hog boys", consistently won races. The group had a live [[Hog (swine)|hog]] as their [[mascot]]. Following a win, they would put the hog on their Harley and take a [[victory lap]].<ref name="H-D timeline 1920s">[http://www.harley-davidson.com/wcm/Content/Pages/H-D_History/history_1920s.jsp?locale=en_US Harley-Davidson] {{webarchive|url=https://web.archive.org/web/20061029110149/http://www.harley-davidson.com/wcm/Content/Pages/H-D_History/history_1920s.jsp?locale=en_US |date=October 29, 2006}} – History</ref> In 1983, the Motor Company formed a club for owners of its product, taking advantage of the long-standing nickname by turning "hog" into the acronym HOG, for Harley Owners Group. Harley-Davidson attempted to trademark "hog", but lost a case against an independent Harley-Davidson specialist, The Hog Farm of West [[Seneca, New York]],<ref>{{cite web |url=http://www.the-hog-farm.com/another-victory.html |title=Decision at the U.S. Second Circuit Federal Court of Appeals N.Y.C.: Corporate Harley-Davidson LOST the Hog Trademark |publisher=The-hog-farm |date=January 15, 1999 |access-date=January 5, 2009 |archive-date=November 3, 2013 |archive-url=https://web.archive.org/web/20131103225753/http://www.the-hog-farm.com/another-victory.html |url-status=live }}</ref> in 1999, when the [[appeal|appellate panel]] ruled that "hog" had become a [[wikt:generic|generic term]] for large motorcycles and was therefore unprotectable as a trademark.<ref>{{cite web |title=Motorcycle manufacturer has no trademark right in 'hog' |publisher=News Media Update |url=http://www.rcfp.org/news/1999/0208k.html |access-date=December 13, 2007 |url-status=dead |archive-url=https://web.archive.org/web/20080221004252/http://www.rcfp.org/news/1999/0208k.html |archive-date=February 21, 2008 |df=mdy-all}}</ref>

===Bobbers===
Harley-Davidson FL "big twins" normally had heavy steel fenders, chrome trim, and other ornate and heavy accessories. After [[World War II]], riders wanting more speed would often shorten the fenders or take them off completely to reduce the weight of the motorcycle. These bikes were called "bobbers" or sometimes "choppers", because parts considered unnecessary were chopped off. Those who made or rode choppers and bobbers, especially members of motorcycle clubs like the [[Hells Angels]], referred to stock FLs as "garbage wagons".<ref>References:
