1979 Honda CB650 · Piston Rings & Pins Buying guide

Confirm bore size before counting ring sets

Standard-size rings, piston pins and retaining clips address different wear or assembly needs. A four-cylinder repair does not turn any one of these listings into a complete engine package.

Parts to consider

Buy rings for the measured engine

The featured ring set replaces reference 13011-426-004 and is standard size. Existing oversize pistons need a separately verified match. Ask the person measuring the cylinders to establish the required ring size before placing an order.

Separate pins from retainers

The genuine Honda pin is sold individually: four pins replace all four. The separate pack contains two 15mm clips, enough for one compatible piston; four packs supply eight clips for all four pistons. Match the piston and pin-retaining arrangement before ordering, especially with aftermarket pistons. Rings, pins and clips are separate products.

Buying questions

How many ring sets rebuild all four pistons?

Four. Each standard-size set contains rings for one piston. A partial repair may need fewer, but every piston being rebuilt must have the correct measured ring size.

Will standard rings suit a rebored engine?

Do not assume so. Check the bore measurement and piston markings first. The available standard-size set is not evidence that an altered engine still uses standard pistons.

Can I reuse piston-pin clips after removing them?

No. Replace piston-pin clips whenever they are removed. Confirm the 15mm size and reference 94601-15000 for the fitted pistons. Two clips serve one compatible piston; four packs provide eight clips for all four pistons.
