Rider Profile

Best ForThis is a high-strung, race-derived supermotard best suited to experienced riders comfortable with sharp power delivery and minimal rider aids.
PurposeBuilt for supermoto track days and aggressive twisty-road carving rather than commuting or long-distance travel.
Rider FitThe tall 918 mm seat height, minimal wind protection, and firm suspension demand a fit, confident rider with good leg length and core strength.
CharacterA raw, lightweight V-twin thumper-style machine that rewards aggressive, playful riding with razor-sharp handling and immediate throttle response.
Not Ideal ForNot a good fit for beginners, taller-distance tourers, or anyone seeking a plush, comfortable daily ride.
