Rider Profile

Best ForThis bike rewards experienced off-road riders and suits intermediate riders looking to progress, as its light two-stroke power delivery and tall seat height demand real skill to control.
PurposeBuilt purely for serious enduro and trail riding, it excels at technical single-track, tight woods sections, and demanding terrain rather than any road-going use.
Rider FitThe very low dry weight and slim chassis make it easy to muscle over obstacles, but the tall 963 mm seat height means shorter riders may struggle to plant their feet confidently.
CharacterIts two-stroke engine gives a light, punchy, and revvy character with an eager, playful feel that thrives when pushed hard and flicked through tight terrain.
Not Ideal ForThis is not the right bike for commuters, passengers, long-distance tourers, or anyone wanting a comfortable, low-maintenance road-focused ride.
