Rider Profile

Best ForThis is a competition-focused motocross machine best suited to experienced off-road riders comfortable with high-revving, aggressive powerbands and race-style handling.
PurposeBuilt purely for motocross racing and off-road competition, not for street use or general recreation.
Rider FitThe tall 960 mm seat height, kick starter, and stiff race suspension demand good rider fitness, strong legs, and off-road riding skill.
CharacterA lightweight, high-strung V2 four-stroke motocrosser with premium suspension components and race-bred chassis geometry designed for aggressive jumps and cornering.
Not Ideal ForThis is not suitable for commuting, touring, passengers, or riders seeking comfort, as it is unlit, unregistered for road use, and has no touring amenities.

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 2010 Aprilia MXV 4.5, 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.
