Rider Profile

Best ForThis bike rewards riders with intermediate to advanced off-road skill, as its tall seat height, minimal weight, and long-travel suspension are unforgiving of hesitant or novice inputs.
PurposeBuilt purely for competitive enduro and technical off-road riding, not as a general-purpose or commuting machine.
Rider FitThe tall 956 mm seat height and firm, long-travel suspension favor taller, fitter riders comfortable standing on the pegs for extended periods.
CharacterA lightweight, high-revving four-stroke enduro weapon that thrives on tight trails, rocky climbs, and technical single-track where agility trumps outright speed.
Not Ideal ForThis is not the right choice for riders wanting a comfortable daily commuter, a passenger-friendly bike, or long-distance paved touring.

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

Feet:

At 956mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with cannot reach comfortably on the 2025 GAS GAS Gas EC 350F, 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.
