Description
Set of 2 standard piston ring sets for the stock bore Honda CB/CL/SL350K twins. If you’re just freshening up your top end and having the cylinders honed, install a fresh set of rings to ensure a tight fit. 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.
Superior tensile strength, ductility and elongation compared to steel rings.
FCD is even stronger than regular cast iron.
FCD is used in many automotive parts, which require strength and durability.
