Rider Profile

Best ForThis is a full-blown 250cc motocross competition bike best suited to intermediate and expert off-road riders, not casual beginners or road riders.
PurposeBuilt purely for closed-course motocross racing and aggressive off-road riding, not for commuting or general road use.
Rider FitIts tall 955mm seat height, lightweight 92kg dry chassis, and firm long-travel suspension demand good rider fitness, strong legs, and confidence standing on the pegs.
CharacterA high-strung, race-bred single-cylinder machine that rewards aggressive, committed riding with sharp handling and explosive throttle response.
Not Ideal ForThis bike is not suitable for new riders, highway travel, two-up riding, or anyone wanting comfort and low maintenance.

2005 Suzuki RM-Z 250 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 2005 Suzuki RM-Z 250, 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.
