How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's designed primarily for commuting, city riding, and learning the fundamentals of naked-sportbike handling and light cornering.
- Built for
- It has a peppy, high-revving twin-cylinder character that rewards spirited throttle use without delivering intimidating power.
- Not ideal for
- It's not the right choice for experienced riders seeking high-speed touring capability, big passenger comfort, or off-road ability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.

Worked out in your browser - nothing is sent to usBased on the maker's published fuel consumption and tank size. Official figures come from a gentle lab test - most riders use 10-30% more fuel than this, so expect less range in real riding, and the last litres of a tank are reserve.
