How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for motocross racing and track practice, not for trail riding, commuting, or general recreation.
- Built for
- A high-strung, rev-happy two-stroke that rewards aggressive clutch and throttle work with sharp, flickable handling on motocross tracks.
- Not ideal for
- Not for adult riders, highway use, long-distance touring, or anyone seeking a comfortable or forgiving first bike.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
