How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for motocross competition and off-road riding, excelling on tracks and rough terrain rather than pavement.
- Built for
- A sharp, aggressive, high-revving single-cylinder bike that rewards precise inputs with explosive acceleration and razor-sharp handling.
- Not ideal for
- Not suitable for riders wanting a comfortable commuter, a passenger-friendly bike, or anything resembling relaxed street or long-distance touring.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
