How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely as a motocross competition bike for closed circuits and tracks, with sharp handling and high-performance suspension rather than everyday usability.
- Built for
- A lightweight, race-bred single-cylinder machine defined by aggressive acceleration, precise cornering, and razor-sharp responsiveness over rough terrain.
- Not ideal for
- This bike is not suitable for riders wanting a comfortable commuter, a passenger-friendly machine, or a long-distance touring companion.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
