Rider Profile

Best ForThis is a specialist competition trial bike best suited to riders with prior off-road or trials experience, though the light weight makes it approachable for committed beginners under instruction.
PurposeBuilt purely for technical trials competition and obstacle riding, not for straight-line speed or general road use.
Rider FitIts extremely low dry weight of 68 kg and slim chassis reward active standing riding and body-weight shifting rather than raw strength.
CharacterA featherweight, high-torque-feel single-cylinder two-stroke that thrives on precise throttle control and momentum management over rocks, logs, and steep sections.
Not Ideal ForThis bike is not for riders wanting a comfortable seat, highway capability, passenger carrying, or any form of touring or commuting.
