How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's designed to deliver sportbike styling, sharp handling, and racetrack aesthetics in a small, restricted-capacity package rather than outright performance.
- Built for
- It has the personality of a miniature superbike, mimicking the RSV4's aggressive styling and handling feel while being accessible and confidence-inspiring for new riders.
- Not ideal for
- It's not suitable for riders wanting real highway speed, long-distance touring comfort, or two-up passenger practicality.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
