As powerful as thunder, as light as a cloud Two universes collide... The legendary Tuono V4 1100 meets the advanced technology of the RS 660 to create the TUONO 660, a motorbike destined to shake up the way you look at the world. Introducing the Tuono 660, the new generation of a versatile naked sport bike. Fun, easy and a heart-breaker on the aesthetics front, its potent combination of power and extraordinary lightness delivers a truly breathtaking and unique riding experience. Like the RS 660, the Aprilia Tuono 660 boasts an incredible weight to power ratio. Its wet weight of just 183 kg for 95 HP is a record-breaker in its category and makes for an accessible naked sport bike suitable for any rider both on the road and track. With five riding modes, of which three provide road options and two are designated for the track, there's plenty of choice for all riding styles and levels of rider, made even more enjoyable by the customizable and easy-to-use electronic instrument panel. Choose from Concept Black, Iridium Grey and the rather special Acid Gold, until now only available on the RS 660, but already setting new standards of style and aesthetics in the motorcycling world.
