Rider Profile

Best ForThis is a demanding, kick-start-only big-bore enduro best suited to experienced off-road riders comfortable with a tall, lightweight, high-compression single.
PurposeBuilt for serious enduro and cross-country off-road riding rather than road use, blending motocross-derived performance with just enough road-legal equipment to link trails.
Rider FitThe tall 940mm seat height, firm suspension, and kick-start big single demand a fit, confident rider with good off-road technique and leg strength.
CharacterRaw, torquey, and purpose-built, this machine rewards aggressive, skilled riding with sharp handling and strong off-road capability rather than comfort or refinement.
Not Ideal ForThis is not a good fit for beginners, shorter riders, or anyone wanting a comfortable, low-maintenance road or touring bike.
