How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's designed as a small-capacity supermotard for zipping through city streets, tight corners, and short playful rides rather than sustained high-speed travel.
- Built for
- It has a nimble, flickable, go-kart-like character with sharp steering geometry and minimal weight, rewarding playful riding over straight-line speed.
- Not ideal for
- It's not suited for riders seeking highway touring, high-speed cruising, serious off-road adventure, or carrying a passenger in comfort.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
