=== Chassis ===
The [[chassis]] are made of [[41xx steel|chromoly]] tubing.<ref>[http://www.haase.it/download/Haase26-CH-11.pdf Example of a CIK-FIA homologation form] – Chassis, 2005</ref><ref name="chassis">[http://www.cometkartsales.com/store/chassis/cpa/images/margayparts/margay17top.jpg Technical picture of a racing chassis] {{webarchive|url=https://web.archive.org/web/20080411105033/http://www.cometkartsales.com/store/chassis/cpa/images/margayparts/margay17top.jpg |date=11 April 2008 }} – [[Margay Products Inc.|Margay]] chassis</ref> There is no [[suspension (vehicle)|suspension]], so chassis have to be flexible enough to work as a suspension and stiff enough not to break or give way on a turn. Kart chassis are classified in the United States as "Open", "Caged", "Straight" or "Offset". All [[Commission Internationale de Karting]]–, [[Fédération Internationale de l'Automobile]]–, or CIK-FIA-approved chassis are "Straight" and "Open".
*Open karts have no roll cage.
*Caged karts have a [[roll cage]] surrounding the driver; they are mostly used on dirt tracks.
*In Straight chassis, the driver sits in the center. Straight chassis are used for [[#Sprint|sprint racing]].
*In Offset chassis, the driver sits on the left side. Offset chassis are used for left-turn-only [[Oval track|speedway]] racing.

The stiffness of the chassis enables different handling characteristics for different circumstances. Typically, for dry conditions, a stiffer chassis is preferable, while in wet or other poor traction conditions, a more flexible chassis may work better. Temperature of the track can also affect handling and may prompt additional chassis adjustments. The best chassis allow for stiffening bars at the rear, front and side to be added or removed according to race conditions.<ref>{{Cite web|url=https://www.kartpartsdepot.com/product_p/007.htm|title=Free It Up - When Too Much Grip Is A Problem|website=www.KartPartsDepot.com}}</ref>

Braking is achieved by a [[disc brake]] mounted on the rear axle. Front disc brakes are used in most shifter kart classes and are increasingly popular in other classes; however, certain classes do not allow them. Shifter karts have dual master cylinders, one for the front and one for the rear, and are adjustable to allow for front/rear bias changes.

Professionally raced karts typically weigh {{convert|165|to|175|lb|kg|abbr=on}}, complete without driver. [[Avanti Kart|Avanti]], Tony Kart, [[Jarno Trulli|Trulli]], [[Birel]], [[CRG (kart manufacturer)|CRG]], [[Gillard (kart manufacturer)|Gillard]], [[Intrepid Kart|Intrepid]], [[Monaco Kart|Remo Racing]], Kosmic, [[Alex Zanardi|Zanardi]] or [[Fernando Alonso|FA Kart]] and [[EKS Motorsport|EKS]] are a few well-known examples of the many European manufacturers of race-quality chassis. Emmick, Coyote, Bandit, Shadow, MGM, Titan, PRC and [[Margay Products Inc.|Margay]] are American companies producing kart chassis.
