How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It exists purely for competitive amateur motocross and off-road racing, designed to build race craft before stepping up to full-size 125cc+ machines.
- Built for
- The two-stroke single delivers a peaky, high-revving power delivery that rewards aggressive clutch and throttle work with sharp, flickable handling on rough terrain.
- Not ideal for
- It is not suitable for road use, daily commuting, passengers, or larger adult riders seeking a general-purpose motorcycle.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
