Aprilia’s RS 660 represents the cutting edge of the new generation of middleweight sportbikes, where more accessible performance has replaced the razor-edge/maximum commitment speed of the old 600 supersport machines. Don’t misinterpret that to mean that the Aprilia is some fat and lazy motorcycle; with its 649cc 270-degree parallel-twin engine pumping out 100 hp at 10,500 rpm and 49.4 lb.-ft. of torque at 8,500 rpm propelling a bike weighing just 403 pounds fully gased, the RS 660 has plenty of excitement on tap. It just doesn’t require expert-level hands to extract it, nor a horse jockey’s flexibility to ride it, with ergonomics that are much more palatable for everyday street use. - Cycle World
