Rider Profile

Best ForBest suited to intermediate or experienced riders comfortable with a light, sharp-handling single-cylinder bike that demands active input.
PurposeBuilt for supermoto-style thrills, carving corners, and attacking twisty tarmac or trackdays rather than covering distance.
Rider FitTall seat height, minimal wind protection, and a firm, aggressive riding position mean it suits fit riders with good balance and stamina.
CharacterA raw, punchy single-cylinder motard that rewards aggressive, playful riding with razor-sharp steering and strong feedback.
Not Ideal ForNot a good fit for riders wanting a plush, relaxed commuter or long-distance touring companion.
