How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A dedicated youth motocross racer built for closed dirt circuits, jumps and berms - pure competition, not transport.
- Built for
- 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.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
