Rider Profile

Best ForBest suited to skilled or dedicated novice trial riders who have specifically trained in balance, clutch control, and standing bike handling techniques.
PurposeBuilt purely for competitive and recreational trials riding, tackling rocks, logs, steps, and technical obstacles at near-walking pace rather than for any kind of speed or distance travel.
Rider FitExtremely light and low-seated, it rewards active standing riding and core-driven balance far more than raw strength, making it accessible to a wide range of body types but demanding in technique.
CharacterA featherweight, razor-responsive machine with a punchy two-stroke and premium Ohlins/Tech suspension tuned for millimeter-precise obstacle control rather than outright power delivery.
Not Ideal ForThis is not the bike for anyone wanting a comfortable seat, highway speed, luggage capacity, or a passenger, since it has no real seat, no touring range, and a tiny fuel tank.
