Set of 2 standard piston ring sets for the stock bore Honda CB/CL/SL350K twins.

Make sure the Letter stamped on the top two rings are facing up when installing them and stagger the ring gaps according to the manual. Set comes with 4 rings and the oil ring spacer. Features: Ductile Iron Casting (FCD) is superior to OEM rings which were sometimes made from steel.
