In the early development days of what we know now as the MV Agusta F4 motor, Ferrari was heavily involved in it's design. The motor they were working on was basically four cylinders taken from the 1990-1992 era Ferrari formula one car motor. This car was not very successful, Alain Prost called it a garbage truck (and was then quickly fired for the remark), so it didn't take long for the engineers at Cagiva to change the design looking for horsepower.
