The Aprilia RS660 is a motorcycle produced by Italian manufacturer Aprilia since 2020. The machine finished second in the UK National Sportbike Championship, a new race series for 2024.[2]
In 2019 Aprilia displayed two sports prototypes, the RS 660 and the Tuono 660, at the 2019 EICMA show. The two were intended to fill a void in the range from the Noale manufacturer, to be able to compete with Japanese companies in the medium-displacement motorcycle sector. Designed as a smaller version of the new RSV4 1100, it shares its lines and chassis, the result of a project born in Piaggio Group Style Center.[3] [4]
The engine, a 659 cm³ twin-cylinder with a double overhead camshaft and connecting rod pins at 270°, is capable of delivering 100 HP of power maximum at 10500 rpm and 67 Nm of torque at 8500 rpm. The frame is an aluminum double beam contributing to a total weight of 169 kg dry. The shock absorbers are adjustable with 41 mm upside-down Kayaba front forks. Electronics are the dedicated Marelli APRC sports system, which gives five performance settings, eight-level traction control, anti-wheelie, ABS, three levels of engine braking, and ride-by-wire throttle control.[5]
In the spring of 2022, the factory version was introduced, which brought a technical update.[6] At the end of the year, a version called RS 660 Extrema was introduced, with modifications to the chassis for track use and lightening of some parts, reducing the weight to 166 kg.[7]
