How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's designed primarily as an approachable everyday commuter and learner-friendly naked bike rather than a performance or adventure machine.
- Built for
- The parallel-twin engine and steel diamond frame give it a mellow, predictable, and easygoing character rather than an aggressive or thrilling one.
- Not ideal for
- It's not the right choice for riders seeking high-speed thrills, serious touring range, or any off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
