Sterzi was in the motorcycle business prior to WWII, and manufactured engines and complete motorcycles from 1947 to 1959.
Originally from Palazzolo sull'Oglio, near Brescia, Vittorio Sterzi with his sons Aldo, Rodolfo and Joseph ran a business selling Dei and Bianchi motorcycles, as well as bicycles. They also manufactured parts for 98cc and 125cc Sachs engines.
Aldo Sterzi had gained considerable mechanical knowledge during the war and applied this to the business. By 1949 they had moved to Brescia and production was in full swing, offering Turismo, Turismo Lusso and Sport models capable of up to 90kph.
In 1954 the model range included 175cc four-strokes in modern frames with suspension front and rear, well-received by both press and public. Their engines were being used by other manufacturers including Benotto, Girardengo and Bonvicini, and by 1958 they were building German Hirth twostrokes under licence. That same year they produced a scooter and a three-wheeler of 160cc. Exports were booming, with machines going as far afield as Mexico and Argentina.
They were very active in motor sports and gained success in the Valli Bergamasche, the Giro Motociclistico d’Italia and the Coppa Augusta, competing against the likes of MV Agusta and Gilera.
Later engines included a 3-speed two-stroke 125cc Tourist model, and from the same period a 125cc SS with four speeds and increased horsepower.
