How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for closed-course motocross racing and aggressive off-road riding, not for street use or transportation.
- Built for
- A light, high-revving, aggressive machine that rewards an active, attacking riding style with explosive acceleration out of corners and razor-sharp handling.
- Not ideal for
- Not suitable for commuting, touring, carrying passengers, or riders seeking comfort and low-maintenance street usability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
