How it rides
Editorial estimate from the spec sheet - not lab tested- Best for

- Built for
- A raw, single-cylinder supermoto that rewards an energetic, playful riding style with immediate throttle response and razor-sharp steering.
- Not ideal for
- Not a good match for riders wanting plush comfort, pillion-friendly ergonomics, or a relaxed high-mileage touring machine.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
