How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for motocross racing and hard off-road riding, excelling on tracks and rough terrain rather than street use.
- Built for
- Sharp, high-revving, and razor-responsive, it rewards committed, active riding with explosive acceleration and precise cornering manners.
- Not ideal for
- It is not suited for commuting, touring, passengers, or casual low-speed street riding due to its lack of lights, mirrors, and road-going comfort features.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
