History: A teenage Giuseppe Gilera apprenticed at the Bianchi Motorcycle company as a mechanic. By 1909 he had designed and built his own motorcycle and started the Gilera Motorcycle Company in Arcore near Milan, Italy. Shortly thereafter he was winning races on motorcycles of his own design. He soon hired engineer and rider Piero Taruffi, who set a land speed record in 1935 of 152 MPH on the four-cylinder 500 CC bike.

The racing success continued after WWII with the new regulations for the 500 CC sporting class. The Gilera Saturno 500 was a success in the sporting class as well as winning the World Road Racing Championship for 500 CC bikes six times in eight years. 1950-1952-1953-1954-1955-1957. This while competing against AJS, BSA, Moto Guzzi and Norton. The Saturno also won the Isle of Mann TT for 500 CC bikes in 1955 and 1957.

The Gilera Saturno Sport was built from 1946 – 1958. About 6026 were built or just 500 bikes per year. Only 859 were produced in 1951.
