How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for supermoto thrills, tight cornering, and tearing up twisty backroads or track days rather than long-distance travel.
- Built for
- A razor-sharp, high-strung street hooligan that rewards aggressive riding with go-kart-like agility and instant throttle response.
- Not ideal for
- Not a good fit for riders seeking a plush, low-effort commuter or a machine capable of comfortable multi-day touring with a passenger.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
