Fits butterfly style Keihin carburetors 1976 - 1987 (not CV!). Backing plate, K&N air filter and chrome top included. 5-1/2" diameter.
K&N's replacement air filters are designed to increase horsepower and acceleration while providing excellent filtration. These filters are washable and reusable and are custom designed to fit into your existing factory air box. Their drop-in design means adding performance is simple. With most motorcycles you simply remove the disposable air filter and replace it with a K&N. This will be THE LAST AIR FILTER YOUR VEHICLE WILL EVER NEED.
