A Brief History of the Marque
Giovanni Moretti began building motorcycles in Macerata using Ladetto, DKW and JAP engines.
In 1947 they developed a 250cc horizontally opposed twin with overhead valves and shaft drive, marketed as the Erfim.
Advertising of the day shows that they also used Alpino 48cc auxiliary engines.
