Rider Profile

Best ForThis bike suits intermediate to experienced off-road riders comfortable with a tall, light, competition-oriented enduro machine.
PurposeIt is built as a serious enduro/off-road competition bike for trails, motocross-style terrain, and technical riding rather than road use.
Rider FitThe tall 945mm seat height and light 98kg dry weight favor taller or more agile riders who can handle standing riding and technical maneuvers.
CharacterIt has the character of a sharp, purpose-built dirt weapon: light, responsive, high-revving, and eager to be thrown around on rough terrain.
Not Ideal ForThis is not a good fit for riders wanting a comfortable highway tourer, a passenger-friendly bike, or a beginner seeking a low, easy-to-handle machine.
