Rider Profile

Best ForThis is a youth-oriented trial machine intended for children and young beginners learning balance and control under adult supervision.
PurposeBuilt purely for low-speed technical trials riding over obstacles, rocks, and slow-balance challenges rather than any kind of speed or distance riding.
Rider FitIts tiny 42 kg dry weight and 600 mm seat height make it extremely manageable for small, lightweight young riders rather than adults.
CharacterA featherweight, nimble trials trainer with a punchy little liquid-cooled two-stroke and a simple 2-speed gearbox designed for precise, controlled throttle response.
Not Ideal ForThis bike is not suitable for adults, highway use, touring, passengers, or anyone seeking real speed or comfort.
