1968 Honda CB450K · Gaskets & Mounting Hardware Buying guide

Separate the port seal from the retaining hardware

The listed gaskets replace references 18291-283-010, 18291-ME9-000 and 18291-MM8-880. They address the exhaust-port sealing component; neither description identifies supplied headpipe retainers or a complete mounting-hardware package.

Use the reference to confirm the sealing part

The product titles use headpipe wording, while the descriptions identify the exhaust-port gasket. Confirm that sealing position and the reference needed for your fitted exhaust. A matching general part name is not a substitute for identifying the exact joint and component you are replacing.

Check quantity and hardware on separate lines

Make one count for the port gaskets and another list for any missing or damaged mounting pieces. The individual and bulk listings specify gasket quantities, not complete hardware contents. This keeps a ten-pack choice from being mistaken for a complete set of exhaust mounting parts.

Buying questions

Can the gasket and retaining collar be treated as the same part?

No. These listings describe the sealing gasket at the exhaust port, not the separate pieces retaining or mounting the pipe. Identify the required hardware independently; buying a gasket does not establish that a collar or fastener is included.

What if I need fewer than ten gaskets?

The individual listing allows an order based on the number of pieces your job requires. The ten-pack is a separate package choice. Count the gaskets needed and compare the product quantities rather than assuming the pack matches one motorcycle’s requirement.

Does the bulk pack confirm a different gasket specification?

The two listings give the same Honda replacement references. Their stated difference is one piece versus ten per pack. Select by verified application and quantity; do not infer a different material or sealing specification from the bulk packaging.

Not sure which part you need?

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