In 1959, the Italian Highway Code was revised, prohibiting motorcyclse with a displacement less then 150cc from using the motorway. MV answered the challenge in 1959 by rolling out a motorcycle that dispaced 150,1cc. With its duplex cradle frame built up from tubes and pressed steel, a fuel tank that bid the top of the cilinder, and a dual seat, it closely resembled the “ Centomila “ 125cc. The most obvoius visual difference was the 150’s dual exhaust tips. MV used the system to reduce back the pressure and increase power. Speaking off power, this Rapido Sport 150 was rated at 10HP at 6.400 rpm, and its 4-stroke engine used an 8:1 compression ratio and a dellort MB 20B carburator to feed power to the 4-speed gearbox. The 150 had a very long commercial succesful life, finally ceasing production in 1970!
