Rider Profile

Best ForThis is a youth-oriented trials machine best suited to young or beginner riders learning balance, clutch control, and obstacle technique.
PurposeBuilt purely for low-speed technical trials riding over rocks, logs, and steep terrain rather than any kind of speed or distance riding.
Rider FitIts tiny 42 kg dry weight and low 600 mm seat height make it extremely manageable for smaller or lighter riders, including children and teens.
CharacterA nimble, featherweight, no-frills trials bike designed to reward precise throttle and balance skills rather than outright performance.
Not Ideal ForThis is not suitable for anyone wanting road use, highway speeds, carrying a passenger, or long-distance touring comfort.
