1982 Honda CB750SC · Piston Rings & Clips Buying guide
Record the piston marking and finished bore size before ordering. Standard, plus 0.25mm and plus 0.50mm rings are distinct choices, and none should be selected simply to compensate for an unmeasured worn cylinder.
Standard piston ringsRings for one piston. Four sets service all four pistons; select after measuring the bores.View part
First-oversize piston ringsPlus 0.25mm ring set for one piston; four sets are needed for all four pistons.View part

A four-cylinder rebuild takes four one-piston ring sets, all matched to the actual piston and bore combination. If machining is planned, agree the finished size with the machinist before ordering. Keep the standard and oversize options separate in your parts list.
The related pin-clip pack contains two 15mm clips. Clips are not piston rings and their pack quantity does not change the number of ring sets needed. Check what your selected piston package already supplies before adding separate retaining pieces.
Each ring set contains rings for one piston. Four sets cover all four pistons; a partial repair needs the number appropriate to the pistons being serviced, in the measured size.
Ring choice must match the assessed bore and piston. Have wear and machining needs measured before buying. An oversize label is not a substitute for checking the finished cylinder and piston combination.
The ring products describe rings for one piston. Pin clips are available separately in packs of two. Check the exact contents of any piston kit rather than treating rings and clips as one package.
