Rider Profile

Best ForThis is a youth/beginner-oriented trials machine best suited to young or novice riders learning technical balance and control rather than experienced adult trials competitors, though its light weight also makes it approachable for smaller adults new to th
PurposeBuilt purely for low-speed technical trials riding over rocks, logs, and steep obstacles, not for any kind of straight-line speed or road use.
Rider FitIts extremely low dry weight of around 64 kg and low seat height make it very easy to manhandle, hop, and balance, favoring finesse and technique over strength.
CharacterA featherweight, purpose-built two-stroke trials bike with a responsive chassis and brakes tuned for precise, controlled obstacle navigation rather than outright performance.
Not Ideal ForThis bike is not suitable for riders wanting highway travel, passenger carrying, long-distance touring, or high-speed riding of any kind.
