How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed for playful, nimble city riding and light supermoto-style fun rather than any serious speed or distance work.
- Built for
- A tiny, high-revving two-stroke supermoto that rewards eager throttle use and sharp cornering lines over outright pace.
- Not ideal for
- Not a fit for riders wanting highway speed, long-distance touring capability, or a passenger-friendly setup.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
