1966 Honda CB450K · Ignition Systems, Coils & Plugs Buying guide

Start with the coil bracket and its connections

Reference 30500-292-672 is one of the coil’s listed Honda replacements. Its attached wires and connector arrangement matter as much as that reference, particularly when an earlier repair has changed the ignition wiring.

Parts to consider

Honda CB Ignition Coil ~ Replaces 30500-292-672

Ignition coil with attached leadThe listed specification is 12V, single-output and 5-ohm primary resistance. Primary wires and a 19-inch spark plug wire are attached. Reference 30500-292-672 is included among its replacements; sold individually.View part

VB05F universal capAn aftermarket universal cap with the 1966 CB450K among its applications. Confirm the plug and lead connections on your motorcycle before choosing it; one cap is supplied per order.View part

YB05F plug capA separately listed aftermarket cap for CB450K restoration or custom work. Compare the installed plug terminal and lead before ordering this type. Sold individually; order the quantity required.View part

Allow for the replacement coil’s lead exit

For a beige Honda coil, the product description calls for mounting the replacement backwards because its wires exit differently. Compare the old coil’s orientation and the new lead path before ordering. The listing provides wire lengths and connectors to help with that comparison.

Avoid choosing a cap from its photo alone

The cap photographs help show the physical shape, but neither description supplies detailed resistance or terminal measurements. Confirm those requirements against your installed plug and lead. If the assembly has been modified, describe those parts when requesting help choosing between YB05F and VB05F.

Ignition ordering questions

What primary wire connections does the coil use?

The listing describes a 6.5-inch blue wire with a dual female bullet connector and a 5.25-inch black/white wire with a male bullet connector. Compare those details with the wiring on your motorcycle before planning the replacement.

Do the cap descriptions confirm their resistance values?

The current YB05F and VB05F descriptions do not state detailed cap resistance. Confirm the specification you need before ordering; the coil’s listed 5-ohm primary resistance is a separate specification and does not establish either cap’s resistance.

Does one coil order include a pair?

The coil is sold each, so one order supplies one coil with its attached wires. The cap listings are also sold each. Count the components you intend to replace and order those quantities separately.

Not sure which part you need?
