How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed primarily as a lightweight sportbike for spirited street riding, commuting, and entry-level track days rather than outright top-speed performance.
- Built for
- A playful, confidence-inspiring small-displacement sportbike that rewards smooth inputs and loves being flicked through corners.
- Not ideal for
- Not a good fit for riders seeking long-distance touring comfort, heavy passenger use, or high-speed highway cruising.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
