1976 Honda CB550K · Piston & Ring Sets Buying guide

Confirm size before choosing piston components

The complete piston kit and separate ring sets are priced by one piston. A standard-size listing is a buying specification, not proof that a previously rebuilt engine still uses standard parts.

Check what the piston kit already supplies

The 58.5mm kit includes a piston, rings, pin and a pair of clips for one piston. If those are the parts you need, compare its contents before separately ordering rings or a pin. Confirm the required size before counting kits for the whole repair.

A reference number is only one check

The ring listings both reference 13011-374-000 and describe standard-size sets for one piston. Compare those details with the fitted piston and its measured condition. The listing reference does not prove the existing engine has never been bored or fitted with replacement pistons.

Common ordering questions

How many pistons does one kit cover?

The 58.5mm kit covers one piston, with rings, pin and a pair of clips. The listing says four kits cover all pistons; choose the quantity for the actual scope of your confirmed repair.

Does one ring set cover the whole engine?

No. Both standard-size ring listings describe rings for one piston, with four sets specified for all pistons. Confirm the fitted piston size and count the pistons needing rings before ordering multiple sets.

Can standard-size parts be chosen from the year alone?

No. The year identifies the listed application but does not reveal previous engine work. Check the current piston and cylinder measurements against the standard-size parts before ordering; an uncertain bore needs confirmation first.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
