How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built as a supermotard, designed for flickable handling on tight, twisty tarmac and light urban duties rather than long-distance cruising or serious off-road work.
- Built for
- Expect a raw, agile, single-cylinder character with strong torque feel low down, sharp steering, and a top speed that reflects its motard focus rather than outright speed.
- Not ideal for
- This is not the right bike for riders seeking high-speed touring comfort, pillion-friendly ergonomics, or serious long-distance highway cruising.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
