Rider Profile

Best ForThis is a full-blooded motocross machine best suited to experienced off-road riders with strong technical skill, not beginners or casual street riders.
PurposeBuilt purely for closed-course motocross racing and serious off-road competition, not for commuting or general road use.
Rider FitAt just 100 kg dry with a tall 950mm seat height and no passenger accommodation, it demands good rider fitness, height, and off-road bike control confidence.
CharacterA light, high-revving, race-bred single-cylinder four-stroke with premium WP suspension and a steel double-cradle frame, delivering sharp, aggressive, track-focused handling.
Not Ideal ForNot suitable for riders wanting comfort, highway touring capability, passenger carrying, or an easy first bike.

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

Feet:

At 950mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2024 GAS GAS MC 450F, 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.
