The Sting is a 125cc supermotard styled machine.

Eligible for European learners to ride in restricted form, it can be de-restricted to produce more power than the standard 10kW (14bhp). A liquid-cooled single-cylinder two-stroke design, it uses reed valve induction and has a large expansion chamber exhaust to improve power delivery.

The styling is borrowed from the firm's successful Duke supermotard, including the large, aggressive twin headlight nosecone. Massively stiff upside-down forks look like they're straight off a full works race machine, and a huge 320mm (12.6in) front brake disc with four-piston caliper gives superb stopping power. The Sting is fitted with 43cm (17in) spoked wheels with sticky sportsbike rubber.
