Rider Profile

Best ForThis is a competition-grade motocross machine best suited to intermediate through expert off-road riders comfortable with a tall, aggressive, race-ready motorcycle.
PurposeBuilt purely for motocross and off-road competition, excelling at jumps, berms, and technical terrain rather than any road use.
Rider FitThe tall 958 mm seat height, firm suspension, and light but demanding standing-riding ergonomics call for good fitness, leg length, and core strength.
CharacterA sharp, high-revving single-cylinder engine paired with a featherweight chassis gives it razor-sharp agility and instant throttle response for aggressive riders.
Not Ideal ForThis is not a fit for commuters, touring riders, passengers, or anyone seeking a comfortable, road-legal, low-maintenance motorcycle.
