Rider Profile

Best For	This bike suits experienced off-road riders comfortable with a peaky two-stroke powerband and tall, minimalist enduro ergonomics.
Purpose	Built purely for technical enduro and trail riding, not for road use or general commuting.
Rider Fit	Its tall 950mm seat height and lightweight 96kg dry chassis demand decent rider fitness and leg length but reward agility over brute strength.
Character	A raw, lightweight two-stroke enduro weapon that thrives on aggressive throttle input and quick direction changes through tight, technical terrain.
Not Ideal For	Not suitable for riders seeking comfort, passenger capability, highway touring, or a forgiving low-maintenance daily ride.

At 940mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2005 GAS GAS EC 125, 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.
