Rider Profile

Best ForThis is a competition-focused 250cc two-stroke motocrosser best suited to experienced or advanced off-road riders, not beginners.
PurposeBuilt purely for closed-course motocross racing and aggressive off-road riding, not for street use or transportation.
Rider FitIts tall seat height, minimal weight, and race-tuned suspension demand strong physical fitness, good bike control, and confidence standing on the pegs.
CharacterA light, high-revving, aggressive machine that rewards an active, attacking riding style with explosive acceleration out of corners and razor-sharp handling.
Not Ideal ForNot suitable for commuting, touring, carrying passengers, or riders seeking comfort and low-maintenance street usability.

At 965mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with cannot reach comfortably on the 2006 Kawasaki KX 250, with a cramped knee angle of around 85 degrees and an upright riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
