Rider Profile

Best ForThis bike suits intermediate to experienced riders who are comfortable with a tall, light, and responsive off-road-focused machine.
PurposeBuilt primarily for serious enduro and trail riding, with excellent power-to-weight for technical terrain rather than sustained road use.
Rider FitThe tall 960 mm seat height and lightweight 110 kg dry weight demand decent rider height and off-road-oriented physical confidence rather than raw strength.
CharacterA sharp, agile, high-revving single-cylinder enduro that rewards an aggressive, standing-up riding style and quick direction changes.
Not Ideal ForNot a good fit for riders wanting a comfortable long-distance tourer, a passenger-friendly bike, or a low, easy-to-manage commuter.
