Camshaft Piaggio OEM Aprilia RX/S 125 years 18-20, RS(4) 125 years 11-20, Tuono 125 years 17-20, intake models

The shaft rotates around its own axis, and the cams mounted on it convert this rotary motion into a short longitudinal motion. 
This longitudinal movement sets the valves in the engine in motion - the up and down corresponds to the opening and closing of the valves.

This item is an original Aprilia/Piaggio brand replacement part.
