In 1950, Graham finished 3rd behind Italian Umberto Masetti (Gilera) and new star Geoff Duke (Norton) of England. He also competed in the 1950 International Six Days Trial held in Wales on an AJS 350. In 1951, Count Domenico Agusta approached Graham to ride for MV Agusta. Frustrated by a lack of development with the AJS, he joined the Italian team to ride and develop their 500 cc four-cylinder machines. Graham failed to score points for MV in the 500 cc class. While the MVs were very powerful, the handling was not as well sorted, and the bikes were considered a "handful". Agusta were not competing in the 350 cc class, so Graham rode a Velocette MkVIII KTT 350 in competition, finishing 6th in class and winning the Swiss Grand Prix. He also finished 8th in the 125 cc class in 1951
