2023 Aprilia® RS 660 Extrema, Aprilia has brought just one new model, or variation of a model, to EICMA 2022. But that one model is the bestselling sportbike for the Italian firm. The 2023 RS 660 Extrema version is based on the RS 660 platform, but adds a number of carbon fiber components that bring the weight down to 366 pounds dry for an attractive power-to-weight ratio, given the 100 hp produced by the 660's parallel twin.
A street-legal SC-Project exhaust system also helps bring the weight down thanks to a silencer in carbon fiber. The mounting bracket for the exhaust bracket also allows for the removal of the passenger pegs. Both the front fender and bellypan are high-quality carbon fiber. The RS 660's electronic suite now includes a new quickshifter software that allows the rider to select GP-style upside-down shifting pattern quickly and easily.
