How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built for learning sharp, precise cornering technique and having fun on twisty roads at accessible speeds rather than for outright straight-line performance.
- Built for
- It behaves like a miniature race replica, rewarding high revs and a light touch with sharp, eager handling despite modest power.
- Not ideal for
- It's not for taller riders, highway commuters, or anyone needing to carry a passenger or luggage over distance.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
