Rider Profile

Best ForThis is a specialist trial machine best suited to riders with dedicated trial skills or those actively learning technical balance-based riding, not general-purpose motorcyclists.
PurposeBuilt purely for competitive and recreational trial riding, focused on tackling obstacles, steep terrain, and technical sections at very low speeds rather than covering distance or achieving top speed.
Rider FitIts extremely light dry weight and low seat height make it easy to manhandle, hop, and balance, favoring agility and standing-based control over seated comfort.
CharacterA featherweight, high-revving two-stroke with razor-sharp low-speed response, precise hydraulic clutch control, and suspension tuned for slow, technical, momentum-less maneuvering rather than flowing speed.
Not Ideal ForThis bike is not suitable for anyone wanting a comfortable commuter, a highway tourer, a passenger-carrying machine, or a bike focused on outright speed.
