The motorcyclist's riding position depends on rider body-geometry ([[anthropometry]]) combined with the geometry of the motorcycle itself. These factors create a set of three basic postures.<ref name="msf-usa.org">{{cite web|url=http://www.msf-usa.org/imsc/proceedings/b-Smith-ThreeDimensionalAnalysisofRiderPosture.pdf|title=A Three Dimensional Analysis of Riding Posture in Three Different Styles of Motorcycle |date=March 2006 |publisher=[[Motorcycle Safety Foundation]] |access-date=31 January 2008 |archive-url= https://web.archive.org/web/20120327075412/http://www.msf-usa.org/imsc/proceedings/b-Smith-ThreeDimensionalAnalysisofRiderPosture.pdf |archive-date= 27 March 2012 }}</ref>

*Sport{{spaced ndash}} the rider leans forward into the wind and the weight of the upper torso is supported by the rider's core at low speed and air pressure at high speed.{{sfn|Davis|Anthony|2011|p=25|ps=&nbsp;"The [sportbike] rider posture is usually canted severely forwrd with his hands pressing onto the handlebar grips, which are designed to keep him over the gasoline tank, a position not intended to maximize comfort. This posture is aerodynamically efficient at high speeds, when wind assists the rider by supporting his body, but at lower speeds quickly results in rider fatigue and stressed wrists."}} The footpegs are below the rider or to the rear. The reduced frontal area cuts wind resistance and allows higher speeds. At low-speed in this position the rider's arms may bear some of the weight of the rider's torso, which can be problematic.
*Standard{{spaced ndash}} the rider sits upright or leans forward slightly. The feet are below the rider. These are motorcycles that are not specialised to one task, so they do not excel in any particular area.{{sfn|Maher|Greisler|1998}}{{sfn|Duglin Kennedy |2005|p=75}} The standard posture is used with [[touring motorcycle|touring]] and commuting as well as dirt and dual-sport bikes, and may offer advantages for beginners.{{sfn|Stermer|2006|p=16}}
*Cruiser{{spaced ndash}} the rider sits at a lower seat height with the upper torso upright or leaning slightly rearward. Legs are extended forwards, sometimes out of reach of the regular controls on cruiser pegs. The low seat height can be a consideration for new or short riders. Handlebars tend to be high and wide. The emphasis is on comfort while compromising cornering ability because of low ground clearance and the greater likelihood of scraping foot pegs, floor boards, or other parts if turns are taken at the speeds other motorcycles can more readily accomplish.{{sfn|Stermer|2006|p=10}}{{sfn|Duglin Kennedy|2005|p=71}}

Factors of a motorcycle's [[ergonomics|ergonomic]] geometry that determine the seating posture include the height, angle and location of footpegs, seat and handlebars. Factors in a rider's physical geometry that contribute to seating posture include torso, arm, thigh and leg length, and overall rider height.
