Rider Profile

Best ForThis is a serious competition enduro machine best suited to experienced off-road riders comfortable with a tall, light, high-strung race bike.
PurposeBuilt purely for enduro racing and technical off-road riding, not as a road or all-round machine.
Rider FitThe tall 925mm seat height, minimal seat padding, and kick-start-only setup demand good fitness, leg length, and off-road riding skill.
CharacterA featherweight, high-revving single-cylinder racer with razor-sharp handling, huge suspension travel, and a raw, focused competition feel.
Not Ideal ForThis bike is not suitable for riders wanting a comfortable commuter, a passenger-friendly tourer, or a beginner-friendly first motorcycle.
