  • Racer X Films: 2019 KTM 150 SX

After over 30 years in the off-road parts business, we never stopped developing and improving our products. That’s why Polisport is an OEM supplier of some of the main motorcycle brands. We create exclusive technologies, constantly think of innovative products, and we always care for the customer. We make performance plastics!
