Standard piston ring set for the stock bore on the Honda CB/CL450K twins and the CB500T twin. 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 to stagger the ring gaps according to the manual.
Set comes with 4 rings and the oil ring spacer. Sold individually, so you will need 2 sets per bike.
Be very careful when installing the cylinder over new rings, it's helpful to have the proper tool to keep the rings compressed as you lower the cylinder over the pistons. Try to use only plastic tipped tools to prevent from scratching aluminum surfaces.
