How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for playful, sharp-handling supermoto antics on tight tarmac circuits, car parks, and mini-track days rather than any kind of serious speed or distance riding.
- Built for
- A light, nimble, high-revving two-stroke supermoto with premium-feel components like an upside-down fork and adjustable monoshock, designed purely for grin-inducing agility over outright pace.
- Not ideal for
- Not a fit for riders wanting real highway speed, long-distance touring comfort, passenger carrying, or genuine off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
