Description

The Società Anonima Frera, founded in Varese (Italy) in 1904, was an important Italian motorcylce manufacturer. After the First World War the company enlarged the production range and took part in sports competitions obtaining various seccesses. Between 1926 and 1932 it developed new models including the Sport K3 motorcycle equipped with the 250 cm³ air-cooled single-cilinder engine.
