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.
