How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built for nimble, playful sport riding on twisty roads and around town rather than outright speed, thanks to its tiny two-stroke engine and sportbike ergonomics.
- Built for
- It has the look and handling feel of a proper sportbike shrunk down, with sharp steering and a lightweight chassis that rewards revving the small two-stroke engine hard.
- Not ideal for
- It's not the right choice for anyone needing real highway speed, long-distance comfort, or the ability to comfortably carry a passenger.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
