Rider Profile

Best ForThis is a high-strung competition motocrosser best suited to experienced off-road riders who are comfortable with a tall, aggressive, powerful dirt bike.
PurposeBuilt purely for motocross racing and rough off-road use, not for street riding or commuting.
Rider FitThe tall 998mm seat height, minimal cushioning, and hard-hitting single-cylinder power delivery demand good rider fitness, leg length, and off-road technique.
CharacterA lightweight, razor-sharp, high-revving racer that rewards aggressive riding with explosive acceleration and pinpoint cornering ability on dirt.
Not Ideal ForThis bike is not suitable for new riders, daily street commuting, passengers, or long-distance touring comfort.
