How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for closed-course motocross racing and serious off-road competition, not for general transportation.
- Built for
- A raw, lightweight, high-revving two-stroke racer that rewards aggressive riding with sharp agility and explosive acceleration on the track.
- Not ideal for
- This is not the right bike for commuting, touring, carrying a passenger, or riders seeking comfort and ease of use.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
