Available in three colors (Concept Black, Iridium Gray, and Acid Gold), the Tuono 660 does away with the RS’s full side fairings. It also swaps out its passenger seat cover for an actual pillion. Lower final drive gearing will give the RS a much needed acceleration boost, especially in the taller gears. A variety of touring-friendly accessories, including fabric tank and tail bags that neaty integrate into the Tuono’s design. Curb weight remains unchanged at 403 pounds with its 4-gallon fuel tank topped off. The 2021 Tuono 660 will arrive in US Aprilia motorcycle dealerships this April.
