Polini

Polini S.p.A. is an Italian manufacturer of tuning parts for motorcycles, mopeds, and scooters. Among other products, they produce cylinders and variators for both racing and road use. They also produce pocket bikes with 50cc up to 15 hp.
The company was founded when the Italian soldier Battista Polini returned from his service in World War II and started making bicycles, which sold very well. The first logo of the company was a ram, which was the coat of arms of Battista's battalion. When the first Vespa and Lambretta scooters emerged in the 1940s, manufacture of parts for these was started.
Today, Polini is owned by Battista Polini's three sons Carlo, Franco, and Piero. Tuning parts are manufactured for all major brands of scooters and motorcycles. Polini also produces a line of miniature folding scooters called SkAtE.
Polini's main competitor is Malossi, which is also based in Italy.
