How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for sharp, playful cornering and sporty commuting rather than outright speed, thanks to its featherweight chassis and small-capacity engine.
- Built for
- A miniature GP-styled sportbike that rewards revving the engine hard and flicking through corners rather than relying on raw power.
- Not ideal for
- Not suited to riders wanting strong highway overtaking power, long-distance touring comfort, or two-up riding.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
