Rider Profile

Best ForThis bike suits experienced off-road riders comfortable with a tall seat height, light dry weight, and aggressive enduro geometry.
PurposeBuilt as a cross-country enduro weapon, it excels at tackling trails, technical terrain, and competitive off-road riding rather than street use.
Rider FitThe 956mm seat height and 104.7kg dry weight demand a taller, fit rider who can manage the bike standing up over rough terrain.
CharacterIt rewards an aggressive, standing-up riding style with sharp, flickable handling and long-travel suspension tuned for absorbing harsh impacts.
Not Ideal ForThis is not a good fit for new riders, commuters wanting comfort, or anyone seeking a passenger-friendly or highway-capable machine.

At 956mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with cannot reach comfortably on the 2026 GAS GAS Gas EX 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.
