How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed as a compact naked sportbike, it excels at short, playful rides around town and light track-day style practice rather than serious performance riding.
- Built for
- Its inverted fork, mono-shock, double front discs, and sporty proportions give it a surprisingly premium, aggressive look and sharp handling feel for its tiny displacement.
- Not ideal for
- It is not suitable for highway travel, long-distance touring, carrying a passenger, or riders seeking real straight-line speed or power.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
