When RSD set out to create an air cleaner, we wanted to make something that improved performance as well as the look of a bike. We ended up revolutionizing what an air cleaner can be in both function and aesthetics. The Venturi Air Cleaner features the best in filtration and flow from industry leader K&N. It is a proven high performance bolt on part that drastically improves the looks of your machine. Our revolutionary backing plate promotes smooth air flow into the carb/throttle body while also providing hidden internal crank case breathers and our new tight seal oil separator insures a clean, leak free ride. Manufactured from Billet Aluminum in the USA, the Venturi is a jewel for the side of your bike.
