Rider Profile

Best ForBest suited to intermediate or experienced riders who appreciate a light, sharp-handling machine that demands active input.
PurposeBuilt for supermotard thrills, tight cornering, and flickable fun on twisty tarmac rather than covering long distances.
Rider FitIts tall seat height and lightweight, top-heavy-feeling standing riding position favor taller or more agile riders comfortable with a dirt-bike-derived stance.
CharacterA sharp, playful, high-revving single-cylinder machine that rewards aggressive riding and quick direction changes.
Not Ideal ForNot the right choice for riders wanting a comfortable, low-maintenance, long-distance touring companion.

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

Feet:

At 900mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2003 GAS GAS SM 250, with a relaxed knee angle of around 145 degrees and a forward-leaning 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.
