Rider Profile

Best ForThis is a purebred competition enduro machine best suited to riders with real off-road experience, as its light weight, tall seat, and punchy two-stroke power delivery are unforgiving for beginners.
PurposeBuilt specifically for enduro racing and technical off-road riding, not as a general-purpose or road-oriented motorcycle.
Rider FitThe very low dry weight around 102 kg makes it easy to muscle over obstacles, but the tall 956 mm seat height and firm long-travel suspension demand decent height, fitness, and standing-riding stamina.
CharacterSharp, light, and eager, this bike rewards aggressive, active riding with instant response and superb agility on tight, technical terrain.
Not Ideal ForIt is not for commuters, passengers, highway touring riders, or anyone wanting a comfortable, low-maintenance road bike.

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

Feet:

At 956mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2026 GAS GAS Gas EX 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.
