This is a new in the package 5pc Clutch Friction Disc Set for the Yamaha AT125 and CT175 models made in 1969 1970 1971 1972 1973 1974. A hard item to find.  Start enjoying your bike...get the back tire spinning..not your clutch! If your clutch feels jerky or slipping this is the fix. This is an easy swap for the home mechanic to do..or get your local shop to help you.  Your bike probably still has the old original clutch plates in it! The top-quality new clutch friction discs set is an important part of getting your engine power to your back wheel smoothly..and allow you to enjoy the trails, woods or track. Your clutch disc set will be mailed to you new in the package. Top quality aftermarket item. Correct replacement for part #437-16321-00 which was superseded by #3HA-16321-00. Great if you are riding, restoring, racing one of these cool Yamahas.  That's is it! We only sell the best. This is a great companion to the Engine gasket set and crankcase seal kit we also have on our website.  Thank you, and look forward to doing business with you!
