Rider Profile

Best ForBest suited to riders with at least some off-road or dirt-bike experience, since the tall seat height and light, nimble chassis reward confident standing-up riding.
PurposeBuilt for trail riding, technical enduro trails, and low-speed off-road exploration rather than any kind of road speed or distance work.
Rider FitThe tall 920mm seat height and lightweight but top-heavy standing riding position favor taller or more agile riders comfortable throwing their weight around off-road.
CharacterA purist lightweight enduro machine that prioritizes suspension travel, low weight, and maneuverability over outright power or refinement.
Not Ideal ForNot for riders wanting highway comfort, passenger capability, or any real straight-line performance.
