How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for motocross racing on closed circuits, jumps, and rough terrain rather than any form of street use.
- Built for
- A razor-sharp, lightweight, high-revving dirt weapon that rewards aggressive, athletic riding with explosive agility over jumps and rough tracks.
- Not ideal for
- It is not suitable for commuting, touring, passengers, or anyone seeking comfort, storage, or street-legal practicality.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
