1973 Honda CB500K · Pistons and Rings Buying guide

Count packages per piston after confirming the size

A standard kit or ring set serves one piston. The individual Honda pin and two-clip pack have separate contents. Check cylinder wear and the existing piston assembly before deciding which of those purchase formats is needed.

Parts to consider

Standard 56 mm kit for one pistonOne kit includes the standard piston, rings, wrist pin and two retaining clips. The source specifies four kits to replace all four CB500K pistons; suitability depends on measured cylinder condition.View part

Check the retaining-clip package

The separate 15 mm clip listing supplies two Japanese-made clips against 94601-15000 and states that one pack serves one piston. It explicitly calls for four packs for a compatible four-cylinder engine. A complete standard piston kit already names its own pair of clips, so account for those contents first.

Rings do not establish the cylinder condition

The offered ring set is standard size and the piston kit is specified at 56 mm. Neither label determines whether a worn or previously machined bore can use them. Have the cylinder and retained piston assessed, then choose parts for that measured assembly instead of expecting new rings to correct every cylinder problem.

Buying questions answered

How many clip packs are specified for all four pistons?

The separate clip listing states eight clips, or four two-clip packs, for a compatible four-cylinder Honda engine. Check the contents of any piston kits being ordered, since each standard kit already includes two clips.

How should I choose and count pins when retaining the pistons?

The Honda pin is sold each, with four specified for complete CB500K replacement. Match the retained piston, pin diameter and references 13111-440-000 / 13111-286-000. If choosing the standard piston kit instead, its pin is already included.

Can I choose standard rings for an engine that has previously been rebored?

Confirm the actual bore size, wear and ring gap before ordering. The standard set is specified for 56 mm and one piston; its CB500K application does not establish suitability for an overbored cylinder. Four sets cover all four standard-size pistons.
