Rider Profile

Best ForThis is a race-bred, high-strung two-stroke supermoto best suited to experienced riders comfortable with sharp power delivery and minimal rider aids.
PurposeBuilt for tight, technical circuits and supermoto competition where flickable handling and aggressive braking matter far more than outright top speed or range.
Rider FitExpect a light, compact, aggressive riding position with firm suspension and minimal seat padding, demanding active rider input and reasonable fitness.
CharacterA raw, punchy two-stroke single with premium suspension and brakes that rewards commitment and precision, delivering feedback and immediacy over refinement.
Not Ideal ForNot suited to riders wanting a plush, low-maintenance daily commuter or a comfortable long-distance touring companion.
