The ITOM brand made a major contribution to the popularity of light motorcycles in the 1950s and 1960s. Success was achieved on the racing circuits and the Grand Prix championships were entered until the factory machines of Honda and Kreidler became supreme. Production began in 1948, with Giuseppe Spotto at the helm and Silvano Bonetto as his right hand man.
The first product was an auxiliary motor for mounting on a bicycle. In 1950, the first light motorcycle was launched with a tubular frame. Shortly thereafter, a two-speed version was introduced. The Esperia was introduced in 1953 with a monocoque frame made of sheet steel. From 1954, the Astor type was supplied in various versions, from sport to competition. These ITOMs reached speeds of 110 km/h, unfaired.
In 1959 the ITOM Tabor was also introduced, a 65cc version with 3.5 hp, three gears and a top of 70 km/h. In 1965, the Astor 4M, the most famous ITOM, came out with four gears, 5.5 hp @ 10,000 rpm and a top of 97 km/h. In the late sixties, an off-the-road model appeared, the Sirio Cross.
In 1973, ITOM stopped producing its own engines, replacing them with Morini. ITOM was not a manufacturer but focused on the assembly of motorcycles / mopeds. Due to financial setbacks in other parts of the company, the motorcycle division was closed in 1975.
