Rider Profile

Best ForThis is a youth trials machine built for kids and very small novice riders just learning bike balance and control, not for adults of any skill level.
PurposeIt exists purely for low-speed technical trials riding, teaching throttle and clutch control over obstacles rather than speed or distance.
Rider FitThe tiny 24.4 inch seat height and 132.2 lb dry weight make it sized specifically for young children with minimal strength or inseam.
CharacterIt behaves as a lightweight, nimble, torquey little trials tool that rewards smooth precise inputs over aggressive riding.
Not Ideal ForIt is not suitable for adults, highway use, touring, or anyone wanting speed or passenger capability.
