How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built for short, sharp sportbike-styled fun around town and on twisty backroads rather than outright speed.
- Built for
- It has the look and stance of a full-size sportbike shrunk down into a nimble, playful 50cc package.
- Not ideal for
- It's not the right choice for experienced riders wanting real power or for anyone planning long-distance touring.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
