How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A pint-sized track-styled sportbike built for spirited backroad riding, carving corners, commuting, and learning proper sport riding skills.
- Built for
- A miniature superbike with real GP-inspired attitude - eager, revvy single that must be worked hard, delivering big-bike thrills at modest speeds.
- Not ideal for
- Not for those wanting outright speed, relaxed touring comfort, two-up practicality, off-road use, or a laid-back upright commuter.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
