How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed as a lightweight sport-styled commuter and learner bike rather than an outright performance machine.
- Built for
- A nimble, sharp-handling small sportbike that rewards revving the little single and flicking it through corners rather than relying on outright power.
- Not ideal for
- Not suitable for riders wanting real highway speed, long-distance touring comfort, or off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
