How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for aggressive sport riding and spirited backroad or track use rather than practical transportation.
- Built for
- A snarling, lightweight two-stroke twin with a peaky power delivery that rewards precise throttle control and revels in fast, flowing corners.
- Not ideal for
- Not a good fit for new riders, pillion-focused riding, long-distance touring, or anyone wanting smooth, low-maintenance daily transport.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
