Rider Profile

Best ForBest suited to intermediate and experienced off-road riders comfortable managing a peaky 2-stroke enduro powerband and tall suspension travel.
PurposeBuilt as a lightweight, competition-focused enduro machine for tight trails, technical terrain, and cross-country racing rather than road use.
Rider FitThe tall 963 mm seat height and dirt-bike ergonomics favor taller riders with good fitness and off-road riding skill.
CharacterA sharp, agile, purely dirt-oriented bike that rewards aggressive, active riding and precise throttle control typical of 2-stroke enduro machines.
Not Ideal ForNot suitable for riders wanting a comfortable commuter, highway tourer, or a bike for carrying passengers.

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.
