Polini history

It all started in the far away 1945.
Immediately after the post war period Italian people move mostly by bicycle.
The founder, Battista Polini, coming back from the front, opens his own workshop and he specializes in the manufacture of bicycles.
Soon the country recovers with pride, and on the thrust of the thriving industrial development, Italian inspiration and creativity soon give their results. One above all, the Vespa, an icon of design and at the same time symbol of rebirth.
Times change but philosophy doesn’t change and the passion that animates the Polini family too: the continuous search for new solutions to ensure the engines better performance, with the maximum safety and reliability as possible. It is also thanks to this commitment that Polini has become a world leader in the design and in the production of special parts for scooters and Maxi scooters.

The Largest Family of Engines for Paramotors

From 2009 Polini production is enhanced with the Polini Thor brand, the most complete range of 2 stroke paramotors engines on the market, from 86 cc to 280 cc for the many demands of flight. A winning choice that has allowed the company to win many national and world Titles in the different specialties.

All the Polini Thor engines, before being shipped all over the world, are tested on the bench tests, in order to ensure their perfect functioning.
