Rider Profile

Best ForBest suited to intermediate-to-advanced off-road riders who already understand motocross bike behavior, as this is a race-focused machine with no electric start or road-going amenities.
PurposeBuilt purely for motocross racing and track-style off-road riding, not for commuting, touring, or general road use.
Rider FitDemands a fit, athletic rider comfortable standing and shifting body weight aggressively, given its tall 940 mm seat height, kick-only start, and light 104.5 kg race-ready mass.
CharacterA high-strung, razor-sharp 250cc four-stroke motocrosser that rewards precise inputs with explosive acceleration and pinpoint cornering agility on dirt.
Not Ideal ForNot for riders seeking comfort, passenger capability, highway touring, or an easy low-maintenance daily ride.

2015 Kawasaki KX 250F Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 945mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2015 Kawasaki KX 250F, 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.
