How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built for supermotard-style fun, flicking through city streets, tight backroads, and light urban stunting rather than any serious distance riding.
- Built for
- A tiny two-stroke supermotard, it's buzzy, revvy, and eager to be thrashed, rewarding an aggressive, playful riding style over smooth cruising.
- Not ideal for
- It's not for anyone wanting real highway speed, long-distance touring comfort, or a bike capable of carrying 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.
