Fusi

Fusi & Co. S.p.A. Milano is a distinguished name in the world of motorcycles, renowned for its storied history that began with its establishment by Achille Fusi. Initially, the company collaborated with FN Motorcycles before launching its own line under the RAS brand in 1932, primarily utilizing FN parts. These early motorcycles featured engines from various sources, including the 175 cc JAP engines produced under license in Italy and Burman gearboxes made under Fiat licenses.

By 1933, Fusi began integrating Italian engines into some of their models. Following Achille Fusi's passing, Luigi Beaux assumed leadership of the company. By 1934, their lineup included motorcycles equipped with 250 cc and 500 cc JAP engines, as well as 175 cc models powered by either JAP engines or engines manufactured by Fusi themselves. Post-1936, the company transitioned to marketing its motorcycles exclusively under the Fusi brand, phasing out the RAS label.

In 1937, Fusi garnered attention with the introduction of a 500 cc powered tricycle designed for light goods transport. In the same year, Fusi acquired Catelli e Fiorani in Pesaro, a company noted for producing CF motorcycles, which were subsequently rebranded as Fusi motorcycles. In 1941, Fusi unveiled the M 25 CFS model, featuring a 248 cc four-stroke engine. This model laid the foundation for future products, including sport bikes that were continuously updated and manufactured throughout the 1950s.
