Rider Profile

Best ForThis is a competition-focused enduro machine best suited to intermediate through expert off-road riders who already know how to manage a light, torquey, high-strung single-cylinder dirt bike.
PurposeBuilt for serious enduro racing and technical trail riding, including Six Days-style multi-terrain competition, rather than street use or commuting.
Rider FitIts extremely low dry weight and tall 963 mm seat height reward an active, fit riding style and favor riders with good leg length and off-road strength over comfort-seeking or shorter riders.
CharacterIt has the character of a razor-sharp, aggressive racing tool: light, flickable, and eager to be thrown around technical terrain rather than cruised.
Not Ideal ForIt is not a good fit for new riders, commuters, passengers, or anyone wanting a comfortable, low-maintenance road or touring bike.
