1974 Honda CB550K · Piston & Rings Buying guide

Rings only or complete pistons

The full kit names a piston, rings, pin and pair of clips. The ring sets instead cover rings for one piston. Their shared standard-size references do not make the ring-only purchase another complete piston package.

Two ring set choices

Both ring sets reference 13011-374-000 and standard size, with one-piston coverage. The premium option expressly identifies Japanese manufacture. Neither description establishes an oversize alternative, so select by the required size and package rather than expecting the premium label to cover a different bore.

Piston pins and clips

The genuine Honda pin listing names 13111-440-000 and 13111-286-000, with CB550K application. Its description does not state a supplied pack quantity. The complete piston kit already names a pin and pair of clips; compare those contents before ordering a separate replacement pin.

Piston questions

How many ring sets do I need for the 1974 CB550K?

Four. Each standard ring set contains the rings for one piston, and both ring set listings say four sets are required to rebuild all the pistons in the four-cylinder engine.

What bore size is the standard piston kit?

The kit is listed as standard size, 58.5mm, for the CB550K from 1974 to 1978 and the CB550F. It includes the piston, rings, piston pin and two pin clips for a single cylinder.

Does the piston kit already include a pin and clips?

Yes. Its written contents name a piston, rings, piston pin and pair of clips for one piston. The separate genuine Honda pin is an additional hardware choice, so check for duplication when planning the order.
