The item that I am selling is a great find!  This is a new in the package standard (STD.) size Piston Ring Set  (this is for the pair pictured..so you get 1 complete set for each piston..so 2 sets) for the 1968, 1969, 1970, 1971, 1972, 1973 Honda CB175 CL175 Scrambler, SL175, CD175.    This is a standard size (STD) 52mm ring set that fit a stock standard size Honda piston.  Perfect part of a restoration or freshen up of your tired motor.   This has the 2 compression rings and the 3pc lower oil control rings for both pistons, everything to get your pistons/ engine running nicely again.   Get your old bike up and running again. We only sell the best! This is a top-quality aftermarket item shipped new in the package.   Good stuff if you are riding or restoring or AHRMA racing one of these cool bikes.  That is it!
