Like many other Italian aftermarket companies, Malossi has humble beginnings as 
a small family business sprung from one man's passion. Mr. Ugo Malossi started 
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 
“Always improve.”
