How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for supermoto-style thrills, tight cornering, and flickable street or track riding rather than long-distance travel.
- 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.
