Inspired by the legendary Tuono V4 1100, infused with RS 660 innovation. The Tuono 660 Factory takes the essence of Aprilia racing and distils it into an agile, intrepid high-performance motorbike. A Euro 5+ 105-hp twin-cylinder engine combines with an ultra-lightweight structure for a category-topping power-to-weight ratio that delivers one of the most exhilarating rides you'll ever experience on the road. Impressive power is complemented by total control courtesy of fully-adjustable hlins suspension, Brembo brakes and the advanced a-PRC electronics suite.
