Rider Profile

Best ForThis is a competition motocross machine best suited to intermediate and advanced off-road riders who already understand how to manage a high-strung, kick-start-only race bike.
PurposeBuilt purely for motocross track riding and racing, not for commuting, road use, or general recreational riding.
Rider FitTall 955mm seat height, no electric start, and a stiff, aggressive suspension setup demand good rider fitness, strong legs, and confident bike control.
CharacterA lightweight, single-cylinder four-stroke racer with a peaky powerband and razor-sharp handling designed for jumps, berms, and hard acceleration out of corners.
Not Ideal ForNot suitable for riders wanting a comfortable daily commuter, a passenger-friendly bike, or a long-distance touring machine.
