Rider Profile

Best ForBest suited to experienced riders who are comfortable with a tall, light, punchy single-cylinder bike that demands active input.
PurposeBuilt for sharp, flickable cornering fun on twisty tarmac and supermoto-style thrills rather than covering long distances.
Rider FitThe tall 910mm seat height and top-heavy single-cylinder vibration mean shorter or less fit riders may find it tiring and intimidating at a stop.
CharacterA raw, mechanical, big-single supermoto that rewards aggressive, engaged riding with immediate steering response and strong midrange torque.
Not Ideal ForNot a good fit for riders wanting plush comfort, pillion practicality, or effortless long-haul touring capability.
