1966 Honda CB450K · Electrical Buying guide

Choose the component that matches the repair

The ignition coil comes with attached wires, while plug caps have their own listings. The cable clip is retaining hardware with a different job. Identify the repair first so the order covers the component you need.

Match the front clip to the existing cable arrangement

The front cable clip holds stop-switch wires against the cable and references 45465-270-000. Compare the existing clip, cable and wire routing before choosing it. The description does not provide cable or wire diameters, so confirm the dimensions if those components have been changed.

Compare the coil’s attached wiring

The replacement coil supplies its plug wire and primary wires. Check those lengths, connectors and the approximately 80 mm mounting centres against your installation. The caps are separate choices; identify the existing plug terminal and lead connection before deciding which type to order.

Electrical parts questions

Will the clip suit a replacement cable or changed controls?

Compare the replacement cable, wire routing and existing clip with the listed retaining part. Reference 45465-270-000 identifies its application, but the description gives no cable or wire diameters. Confirm those measurements before selecting it for an altered installation.

Will the new coil mount in the same orientation as my old one?

The listing specifically notes backwards mounting when replacing a beige Honda coil because the wires exit differently. Compare your old coil, bracket and lead path with the replacement specifications; a previous owner may have fitted a different coil.

Which cap should I choose if the plugs have been changed?

Identify the plug terminal and ignition lead first. YB05F and VB05F are separate aftermarket cap choices, and their descriptions do not provide all connection measurements. Send the fitted plug and lead details if you cannot confirm the match.

Not sure which part you need?

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