Rider Profile

Best ForBest suited to riders with at least some off-road or dirt-bike experience, since the tall seat height and light, flickable chassis reward confident standing and body-positioning skills.
PurposeThis is a dual-sport built primarily for trail riding, technical off-road terrain, and green-lane exploration, with street legality as a practical bonus rather than its main focus.
Rider FitThe 935 mm seat height and 144 kg dry-oriented weight make it easy to muscle around off-road but demanding for shorter riders at a stop, who may struggle to flat-foot it.
CharacterA raw, mechanical single-cylinder enduro that feels light, torquey at low revs, and eager to be thrown into ruts, gravel, and single-track rather than cruised on smooth tarmac.
Not Ideal ForNot a good fit for riders wanting sustained highway speed, plush long-distance comfort, or a bike that carries a passenger with any real comfort.
