Rider Profile

Best ForThis is a cross-country race machine best suited to experienced off-road riders comfortable with a tall, aggressive competition bike.
PurposeBuilt for cross-country and enduro-style racing, prioritizing light weight, high-revving power delivery, and serious suspension travel over comfort or practicality.
Rider FitThe 954 mm seat height and firm long-travel suspension demand good rider fitness, leg length, and stamina, especially over long off-road stints.
CharacterA raw, high-strung single-cylinder racer that rewards an active, aggressive riding style and punishes passive throttle input.
Not Ideal ForThis is not a good fit for new riders, commuters, or anyone wanting a comfortable, low-maintenance road-going machine.
