Raced: 1959-1961 and 1964 season
Following an initial experiment in 1955 that combined two 125 cc cylinders, a new engine was created. The results were remarkable. It victoriously debuted in the German Grand Prix on June 14, 1959 with C. Ubbiali. In February 1966 in Spain, G. Agostini raced it again, taking its final win.
