Radiator Louver Mesh. This is where it all began, 30 years ago - Polisport started building aftermarket parts so that everyone could enjoy their bikes without worry and with even better looks and improved performance. Performance plastics kick-started its success and are still the core of Polisport. Protects the radiator without blocking the airflow. Can be easily clipped and unclipped on the radiator louvers without disassembling the radiator scoops. Polisport's meshes are designed to perfectly fit each radiator louver. Patented clip-on system. Note: ONLY compatible with Polisport radiator louvers, which are sold separately.
