How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed as a nimble supermoto-style street bike, blending a lightweight chassis and sticky 17-inch wheels for sharp handling over long-distance comfort or off-road capability.
- Built for
- A characterful, torquey single-cylinder engine paired with a light 171kg chassis gives it a raw, direct, go-kart-like feel typical of late-90s supermotos.
- Not ideal for
- This is not the right bike for riders seeking a smooth, wind-protected long-distance tourer or a machine with genuine off-road suspension travel.
