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. Double soft rubber ribs provide an excellent fit to keep water, bugs and dirt out of your exhaust system. Convenient plastic handle. 2-Stroke version fits most two-strokes. 4-Stroke version fits most four-strokes. Sold individually.
