1972 Honda CB450K Coil Leads, Plug Caps & Contact Points

Choose ignition components for your 1972 CB450K by their own electrical, connection and mounting details. The coil provides a measured lead layout; the plug caps give fewer specifications. Identify the point side and condenser separately before calculating the parts needed for the service.

1972 Honda CB450K · Ignition Systems, Coils & Plugs Buying guide

Use coil specifications without extending them to plug caps

The individually sold coil is 12V, single output and 5-ohm primary, with attached wiring. Both cap choices are aftermarket parts sold each without stated resistance values. Contact points identify separate left and right references, while the condenser names its own replacement references.

Parts to consider

Honda CB Ignition Coil ~ Replaces 30500-292-672 Single-output coil with measured leads12V coil, 5-ohm primary and 19-inch spark plug wire, sold each with leads attached. Mounting centres are approximately 80mm. Compare its wiring and bracket arrangement, including the reversed-mounting note for a beige Honda coil.View part Universal Motorcycle Spark Plug Cap ~ VB05F Aftermarket cap with connection checksVB05F spark plug cap sold each for the listed Honda applications. Its description asks for electrical and connection checks without supplying cap resistance or full terminal dimensions. Match it to the plug, lead and ignition being used.View part Honda CB500/CB450 Spark Plug Cap ~ YB05F Aftermarket cap for restoration or custom workYB05F cap sold individually and described for restoration or custom work.

Compare the complete attached-wire layout

The coil specifies a 6.5-inch blue wire with dual female bullet connector and a 5.25-inch black/white wire with male bullet connector. Assess those lengths alongside its 19-inch plug wire and mounting orientation. Where a bracket or harness has changed, confirm the paths and connections needed by the retained ignition.

Build a point and condenser order from individual parts

The left point references 30204-292-003 / 30204-292-154 and the right point 30203-292-003 / 30203-292-154. The condenser uses 30250-369-004 / 30280-292-672 / 30280-292-671. Read supplied quantities before treating these separate descriptions as a combined pair or service kit.

Selecting ignition leads and service components

Does a matching cap name establish its resistance?

Neither cap description gives a resistance value. Confirm the requirement for the plug, ignition lead and ignition system being retained before choosing between them. Do not infer a value from the cap designation or use the coil’s primary resistance as a cap specification.

What should I compare if the coil bracket was changed?

Check the approximately 80mm mounting centres and the wire exits against that bracket, then compare all stated lead lengths and bullet connectors with the retained wiring. The listing’s beige-coil replacement note changes mounting orientation; bracket spacing alone cannot resolve the lead route.

Can I identify both point sides from one replacement reference?

The left and right products have distinct 30204-292 and 30203-292 references. Compare the component and side being repaired and confirm each purchase’s supplied quantity. The shared motorcycle application does not turn one point listing into an explicit two-sided package.
