Ferrari has a history with MV Augusta:
"The F4 engine is a liquid cooled inline four cylinder (4-stroke) with two overhead camshafts (
DOHC), 16 radial valves, electronic multipoint injection, induction discharge electronic ignition and following capacity variants: 749.5 cc, 998 cc and 1078 cc. The engine was derived from the 1990–1992
Ferrari Formula One engine. Early in the design process Ferrari engineers assisted in the development of the engine. MV (Cagiva at the time) quickly deviated from the Ferrari design, but they kept one important feature, the radial valves. The F4 engine is unique in the sense that it is the only radial valved motorcycle engine currently in production."
