Rider Profile

Best ForThis is a specialist machine best suited to experienced riders who understand supermoto handling and a punchy single-cylinder power delivery.
PurposeBuilt for supermoto competition and aggressive backroad or track riding where sharp handling and light weight matter far more than outright comfort.
Rider FitExpect a tall, firm, motocross-derived seating position with minimal wind protection, demanding good fitness and confidence standing on the pegs.
CharacterA high-strung, race-bred single with premium suspension components that rewards an active, committed riding style with razor-sharp cornering ability.
Not Ideal ForNot a sensible choice for riders wanting relaxed daily commuting, long-distance touring, or carrying a passenger in comfort.
