Rider Profile

Best ForThis is a purebred motocross weapon best suited to experienced off-road or track riders comfortable with a peaky 2-stroke powerband and no electronic aids.
PurposeBuilt exclusively for closed-course motocross racing and aggressive off-road riding, not general transportation.
Rider FitThe tall 38.4-inch seat height, light 227 lb wet weight, and firm suspension demand an athletic rider who can stand, shift weight, and absorb jumps and rough terrain actively.
CharacterA raw, high-strung 2-stroke that rewards precise clutch and throttle control with explosive acceleration and razor-sharp handling on the track.
Not Ideal ForThis bike is not for commuters, passengers, touring riders, or anyone seeking comfort, low seat height, or road-going practicality.
