Rider Profile

Best ForThis is a competition motocross machine best suited to intermediate and advanced off-road riders who already understand how to manage a high-strung, kick-start-only race bike.
PurposeBuilt purely for motocross track riding and racing, not for commuting, road use, or general recreational riding.
Rider FitTall 955mm seat height, no electric start, and a stiff, aggressive suspension setup demand good rider fitness, strong legs, and confident bike control.
CharacterA lightweight, single-cylinder four-stroke racer with a peaky powerband and razor-sharp handling designed for jumps, berms, and hard acceleration out of corners.
Not Ideal ForNot suitable for riders wanting a comfortable daily commuter, a passenger-friendly bike, or a long-distance touring machine.

2010 Suzuki RM-Z250 Rider Ergonomics Assessment

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

Feet:

At 955mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2010 Suzuki RM-Z250, 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.
