Rider Profile

Best ForThis is a race-bred enduro machine best suited to intermediate or advanced off-road riders who can handle a light, high-strung two-stroke.
PurposeBuilt for desert racing, enduro competition, and technical off-road trails rather than road use or commuting.
Rider FitIts very light dry weight and tall, narrow ergonomics reward an active standing riding style but demand decent fitness and leg strength for standing over rough terrain.
CharacterA punchy, high-revving two-stroke single with premium suspension components that gives sharp, aggressive, and highly responsive handling on loose and uneven surfaces.
Not Ideal ForNot a good fit for riders wanting a comfortable daily commuter, a passenger-friendly bike, or a machine suited to sustained highway touring.
