Here is a great find. This is a new in the package ring set  (complete set of rings for both (2) pistons) for the  1974 1975 1976 1977 1978 1979 1980 1981 1982 1983 and 1984 Yamaha XS650 motorcycles.  If you are looking to replace your rings on your stock original size Yamaha piston, then this is the correct part for you. This is correct for OE part # 447-11610-00.  This is a standard 75mm size (STD) ring set.  Top quality aftermarket item.  This has the 2 compression rings and the lower 3pc oil control ring, everything to get your piston compression back where it should be. . A great deal!  These also interchange with the European Yamaha 533 part # XS650 piston rings.  These will not fit the early model 1970-1973 Yamaha pistons.  Get your old bike up and running again. We only sell the best!
