Aprilia lures would-be sportbike riders to the Italian side with its all-new RS 660 ($11,299). The RS 660 leverages Aprilia’s production superbike technical know-how to build a more functional real-world middleweight. Unlike the dedicated supersport segment (think Japanese-made 600cc bikes), the RS (acronym for RennSport) isn’t designed for competition. Instead it’s made for street bikers who want a capable sportbike for the modern world.
