How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for zipping through twisty roads and city streets with sportbike styling and a playful, lightweight chassis rather than for outright speed.
- Built for
- A pint-sized sport bike with race-inspired running gear, a peppy two-stroke engine, and go-kart-like agility that punches above its small displacement.
- Not ideal for
- Not the right choice for riders wanting sustained highway speeds, long-distance touring comfort, or off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
