When it comes to quality performance scooter parts, MALOSSI is the long-standing
industry leader for price, selection, and quality. All Malossi components are
made 100% in Italy. All final manufacturing, assembly, and research and

tuning and manufacturing the best performance carburetors in the region under
the tutelage of his mechanically accomplished father, Armando. In 1957, with the
vision of Ugo, Malossi was formally born. Ugo's son and daughter are the active
managers of the company and they share in their father's passion and vision to
