The Aprilia RS 660 35KW is the A2 licence version of Aprilia's RS 660 sports bike, with its power restricted to suit the A2 limit. It uses a liquid-cooled 659cc parallel twin derived from the front cylinders of the RSV4.
It keeps the full electronics package, including a six-axis inertial platform and traction control. It can be de-restricted when the rider moves to a full licence. Rivals include the Yamaha R7 and Kawasaki Ninja 650.
