How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built primarily for track riding and high-performance sport road use, with race-derived electronics and chassis geometry prioritizing outright speed and cornering precision.
- Built for
- A razor-sharp, race-bred superbike that rewards commitment and skill with explosive acceleration, crossplane-crank character, and pinpoint cornering ability.
- Not ideal for
- Not suitable for beginners, commuters seeking comfort, or riders wanting a relaxed upright touring or passenger-friendly experience.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.

Worked out in your browser - nothing is sent to usBased on the maker's published fuel consumption and tank size. Official figures come from a gentle lab test - most riders use 10-30% more fuel than this, so expect less range in real riding, and the last litres of a tank are reserve.
