A supermoto-styled 125 two-stroke, sold in Europe in a learner-restricted form that could be de-restricted for more power. It is a liquid-cooled single with a large expansion chamber, and its styling borrows from KTM's Duke supermoto, with a twin-headlight nose, upside-down forks, a 320 mm front disc and 17-inch spoked wheels.
