How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for motocross and off-road competition, excelling at jumps, berms, and technical terrain rather than any road use.
- Built for
- A sharp, high-revving single-cylinder engine paired with a featherweight chassis gives it razor-sharp agility and instant throttle response for aggressive riders.
- Not ideal for
- This is not a fit for commuters, touring riders, passengers, or anyone seeking a comfortable, road-legal, low-maintenance motorcycle.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
