Rider Profile

Best ForFor young or lightweight racers progressing beyond minis; demands competent throttle and clutch control to manage its peaky two-stroke power.
PurposeA dedicated youth motocross racer built for closed dirt circuits, jumps and berms — pure competition, not transport.
Rider FitTiny and feather-light with a 750mm seat, 280mm ground clearance and long-travel WP suspension; sized for smaller riders on 17/14 wheels.
CharacterSharp, revvy and aggressive — a snappy liquid-cooled two-stroke that rewards commitment with explosive acceleration and razor agility.
Not Ideal ForNot for road use, commuting, touring or passengers; no lights, kick-start only, knobby tires and race-only intent make it street-illegal.
