RS 660 Extrema is the sportiest version among the RS 660 models, featuring a range of racing elements that enhance its dynamic qualities and reduce its dry weight to just 166 kg, setting a new benchmark in the power-to-weight ratio. The “Extrema” suffix unmistakably evokes another exceptional Aprilia from the early '90s: the RS 125 Extrema, one of the most powerful and fastest 125 cc bikes ever made.
