Rider Profile

Best ForThis is a full-blown motocross machine best suited to intermediate through expert off-road riders who already know how to manage a high-strung, clutch-dependent two-stroke-like power delivery from a modern 250cc four-stroke.
PurposeBuilt purely for closed-course motocross racing and aggressive off-road riding, not for transportation or general road use.
Rider FitIts light 109.2 kg wet weight and tall 955 mm seat height demand an active, standing riding style and reward riders with good fitness, leg strength, and confidence throwing the bike around.
CharacterSharp, flickable, and eager to change direction, with a stiff perimeter aluminum frame and race-tuned suspension geometry that favor jumps, berms, and rapid transitions over comfort.
Not Ideal ForThis is not the bike for commuting, highway travel, carrying a passenger, or riders wanting a plush, low-maintenance, easygoing ride.

2024 Kawasaki KX250 Rider Ergonomics Assessment

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

Feet:

At 960mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2024 Kawasaki KX250, 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.
