How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a supermoto for tight, technical roads and track days where flickable handling and strong brakes matter more than outright top speed.
- Built for
- A punchy, single-cylinder hooligan machine that feels eager, direct, and playful, encouraging sliding and hard braking into corners.
- Not ideal for
- Not a good fit for riders wanting long-distance comfort, pillion capability, or a smooth, vibration-free ride.
