A Brief History of the Marque
In 1955 the company founded in Borgo Piave di Latina (Società Motori Deca) built a 48cc four-stroke moped (ciclomotore) and a 100cc four-stroke twin with four-speed gearbox.
In 1957 they produced two lightweight motorcycles of 100 and 125cc - these were four-stroke twins built by joining two smaller engines together. These had a four-speed gearbox and suspension front and rear.
