• Sport — the rider leans forwards into the wind and the weight of the upper torso is supported by air pressure as long as the motorcycle is travelling at speed, typically above 50 mph (80 km/h). The footpegs are below the rider or to the rear. The reduced frontal area cuts wind resistance and allow higher speeds. However, at low-speed this position throws the weight of the rider onto the arms instead, and this is quickly tiring to the wrists of unfamiliar riders. Moreover, the sports position makes it more difficult for the rider to look around and foot through traffic. Many sport bikes have narrow, swept-back handlebars, or clip-ons (short stubs clamped to the telescopic fork tubes). Following the style of racing bikes, most have full-fairings and often come with almost complete engine enclosure, although motorcycles with a sport riding position are becoming more diverse with the marketing of factory naked bikes, streetfighters, retro cafe racers, and other blends of styles, having varying riding positions somewhere in the range from sport to standard.
• Standard — the rider sits upright or leans forwards slightly. The feet are below the rider, not too far to the front or back. These are straightforward, versatile motorcycles that are not too specialised for one task, but don't excel in one area either. The standard posture is used with touring and commuting as well as dirt and dual-sport bikes, and is good for beginners. The rider enjoys the benefits of freedom of head movement, good visibility in all directions, and easier use of the feet while moving through stationary traffic.
• Cruiser — the rider sits at a lower seat height with the upper torso upright or leaning slightly rearwards. Legs are extended forwards, sometimes out of reach of the regular controls on cruiser pegs. The low seat heights can be a consideration for new or short riders. Handlebars tend to be high, and wide. Harley-Davidsons are exemplars of this style. 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 types of motorcycles can do.
Factors of a motorcycle's 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.
