Rider Profile

Best ForThis is a serious offroad enduro machine best suited to intermediate and experienced riders comfortable with tall seat height, light weight, and aggressive suspension travel.
PurposeBuilt for technical trail riding, enduro competition, and rough terrain rather than pavement use.
Rider FitIts low dry weight and narrow chassis make it easy to muscle around obstacles, but the tall stance and firm long-travel suspension demand decent rider fitness and confidence standing on the pegs.
CharacterA raw, purpose-built dirt weapon with a torquey big-bore single, minimal creature comforts, and a chassis tuned purely for agility over rocks, ruts, and trails.
Not Ideal ForNot a good fit for riders wanting a comfortable commuter, a passenger-friendly bike, or sustained high-speed road touring.
