Rider Profile

Best ForBest suited to riders with dedicated trials skill or those actively learning the discipline, as this is a purpose-built competition tool rather than a general-purpose bike.
PurposeBuilt specifically for technical trials competition and obstacle riding, prioritizing extreme low-speed control over any kind of speed or distance capability.
Rider FitIts featherweight dry weight and tall, slim chassis reward an active, standing riding style and good balance far more than raw strength.
CharacterA precise, feather-light, high-revving two-stroke instrument designed for balance, throttle control, and momentum management over obstacles.
Not Ideal ForNot suitable for anyone wanting road use, highway speed, touring comfort, or a passenger-carrying machine.
