Rider Profile

Best ForThis is a full-size open-class motocross weapon best suited to intermediate through expert riders comfortable with aggressive power delivery and a tall, firm chassis.
PurposeBuilt purely for motocross racing and hard off-road riding, excelling on tracks and rough terrain rather than street use.
Rider FitIts 38-inch seat height, lightweight 243 lb wet weight, and race-oriented ergonomics demand good rider fitness, leg length, and standing-riding technique.
CharacterSharp, high-revving, and razor-responsive, it rewards committed, active riding with explosive acceleration and precise cornering manners.
Not Ideal ForIt is not suited for commuting, touring, passengers, or casual low-speed street riding due to its lack of lights, mirrors, and road-going comfort features.
