The new 4-cylinder short stroke engine with radial valve is the soul of the MV Agusta F4 RR. The engine is completely new and is inspired by MV Agusta’s experience in competition. Apart from the engine case castings, the arrangement of cylinders and a few other elements the 4 cylinder RR engine shares little with that of the previous F4 - 2012 MV Agusta F4 RR
