1978 Honda CB750A · Piston & Ring Sets Buying guide

Select rings by the measured size and repair quantity

Confirm the piston and cylinder requirements before choosing standard or oversize rings. Then count the positions included in the repair and identify any separate pin or retention-hardware needs.

Parts to consider

1976-78 Honda CB750 Piston Ring Set ~ Standard Size Standard piston ring setThe standard-size listing supplies rings for one piston and names reference 13011-392-004. It specifies four sets for all four pistons.View part 1976-78 Honda CB750 Piston Ring Set ~ 1st Oversize +0.25mm First-oversize ring setA +0.25mm ring set for one piston, listed for the CB750A Hondamatic.

Choose size from the engine assessment

Keep the measurement and piston markings with the repair notes. Model year cannot establish the size inside an engine that may have been rebuilt. Compare that assessed requirement with the exact ring product before ordering.

Keep pins and clips separate from the ring order

The piston pin has its own replacement reference, and the clip listing specifies two 15mm clips per packet. Neither turns the ring set into a piston kit. Inspect the pin and retention components, then choose their quantities independently of the number of ring sets ordered.

Common questions

How many pistons does one ring set cover?

Each of the three ring descriptions says one piston per set and four sets for all four pistons. Base the order on the actual repair scope. A ring set is not described as including a piston, pin or clips.

Does the guide specify the original bore dimension?

No bore dimension is stated in these ring listings. Standard and the two oversize descriptions are the available product designations. Establish the installed piston and cylinder measurements before selecting, rather than borrowing a bore figure from another CB750 model.

Are pin clips supplied with the piston pin?

The pin and clip packet are separate listings. The clip packet explicitly supplies two 15mm clips; the pin description identifies its replacement reference without listing clips as contents. Review both descriptions before deciding what the inspected repair needs.
