NPR brand OEM standard piston rings for the Honda DOHC CB750's. Sold individually, so you will need 4 sets per bike. 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 ring is facing up when installing them and stagger the ring gaps according to the manual.
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.
Made in Japan.
