Rider Profile

Best ForThis bike suits experienced riders who are comfortable with a light, high-strung single-cylinder machine that demands active input.
PurposeBuilt for supermoto thrills, it excels at flickable cornering, tight city carving, and aggressive canyon or track-day riding rather than long-distance travel.
Rider FitThe tall seat height and minimal weight favor taller, fit riders who can confidently handle a top-heavy stance at stops and stand while riding.
CharacterExpect a raw, punchy, and playful character with sharp throttle response and razor-quick handling typical of a big-bore thumper supermoto.
Not Ideal ForThis is not the right choice for beginners, passengers, or riders seeking comfort, wind protection, or extended touring range.
