In 1958, responding to the new Italian Road Law (Italian: Codice della strada), which closed highways for motorcycles of 125 cc or less, the company released a 150 cc version of the MV Agusta 150 RS (Rapido Sport). Its 10 hp engine accelerating the motorcycle up to 110 km/h, allowed it to stay in the stream (the most popular car of those times — the Fiat 500 — had a lower maximum speed). The same engine, detuned to 7 hp, was also installed on the small three-wheeled scooter Centauro. This machine with a load capacity of 350 kg already had a cab.
