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