The MV's first racing success came later with the 125cc DOHC four-stroke engine. The 1950 season and 1951 season were development years. Racing efforts only produced a fifth-place finish at the Dutch TT in 1950. The 1951 results were only slightly better. The 1952 season saw the introduction of telescopic forks, full width alloy brake hubs and a sleek fuel tank on the 125 cc race bike. Britain's Cecil Sandford piloted the new MV 125 to a 1952 Isle of Man TT victory and went on to win MV Agusta's first world championship. And in September that year Leslie Graham made Count Agusta the happiest man alive by winning MV's first 500 cc Grand Prix, on the hallowed asphalt of Monza, beating Gilera's Umberto Masetti by 58 seconds. Giuseppe Commendatore Gilera was so incensed that he lodged a protest, claiming MV's engine was oversize. It wasn't.
