Rider Profile

Best ForThis is a raw, high-strung motocross machine best suited to riders who already have solid off-road experience and can manage a peaky two-stroke power delivery.
PurposeBuilt purely for motocross competition and rough terrain, not for street riding or commuting.
Rider FitExpect a demanding, physical ride with a tall, firm seat, aggressive stance, and no wind or weather protection, requiring good strength and stamina.
CharacterA lightweight, snappy, and aggressive 1980s two-stroke motocrosser that rewards an active riding style and rewards throttle control on jumps and berms.
Not Ideal ForNot suitable for new riders, daily commuting, passengers, or anyone wanting comfort or long-distance touring capability.
