About Polini: Polini has been on the scene since 1945, and is rumored to have built a big bore kit for the first Vespa before Piaggio even knew they were going to build the prototype. They have built on their long history of adding power and performance to vintage Vespa scooters by continually coming out with performance parts for modern Vespas, Honda Ruckus and Yamaha Zuma scooters.
