How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's designed as an affordable, sporty-looking commuter for short urban trips rather than any kind of serious performance machine.
- Built for
- It mimics full-size sportbike styling and a six-speed gearbox in a tiny two-stroke package, giving a playful, revvy feel despite minimal outright power.
- Not ideal for
- It's not for riders wanting real speed, highway touring capability, or the ability to carry a passenger any real distance.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
