The small Italian manufacturer based in Rastellino and Panzano has a complex history. The firm's initials are from the names Mario Lorenzoni (financier), Gianni Ribuffo (rider) and Paolo Marcheselli (engineer). Formed in 1973 the company built a 125cc two stroke twin GP machine powered by Yamaha. They also build a 50cc GP motorcycle. Later, in collaboration with ex-Benelli Works Mechanic Eugenio Lazzarini, LGM built a 50cc GP motorcycle based on a Kreidler engine. In 1980 Eugenio Lazzarini won the World Championship on this motorcycle, entered as an Iprem."
