Rider Profile

Best ForBest suited to experienced riders who are comfortable with a light, sharp-reacting bike that demands active input.
PurposeBuilt for supermoto thrills - carving corners, wheelies, and aggressive street or track riding rather than long-distance travel.
Rider FitA tall seat height and firm, minimal suspension travel mean shorter or less fit riders may find it physically demanding over time.
CharacterA raw, high-revving single-cylinder hooligan bike that rewards precision and punishes hesitation.
Not Ideal ForNot for riders seeking a plush, comfortable ride for touring or relaxed daily commuting.
