How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed for supermoto racing and aggressive, playful road riding on twisty tarmac rather than long-distance or utilitarian use.
- Built for
- A raw, high-revving big-bore single with race-derived suspension and brakes, giving it an intense, focused, and highly responsive personality.
- Not ideal for
- Not suitable for riders wanting plush comfort, pillion capability, long-range touring, or a forgiving, low-maintenance daily commuter.
