Rider Profile

Best ForBest suited to intermediate or experienced riders who are comfortable with a light, high-strung single-cylinder machine that demands active riding input.
PurposeBuilt for supermoto thrills and razor-sharp cornering on tight, twisty tarmac rather than long-distance travel or heavy off-road work.
Rider FitThe tall seat height, minimal weight, and firm suspension favor taller, fitter riders who can comfortably handle a physical, aggressive riding position.
CharacterA raw, playful, and punchy machine that rewards aggressive throttle and brake inputs with immediate, go-kart-like responses.
Not Ideal ForNot a good fit for riders seeking plush comfort, pillion capability, or a relaxed long-haul touring experience.
