1973 Honda CB450K · Electrical Buying guide

Compare the supplied component with its surroundings

The coil specifies its primary rating and attached wire lengths. The headlight assembly names a halogen unit, case and trim, with an old-mounting-bolt requirement for CB450K. Front brake-switch wiring has a separate reference. Battery chemistry determines the suitable charging-control version.

Parts to consider

Honda CB Ignition Coil ~ Replaces 30500-292-672

Ignition coil supplied with attached leadsSingle-output 12V coil with 5-ohm primary resistance, a 19-inch plug lead and approximately 80mm mounting centres. Sold each. Compare the retained ignition and the stated beige-coil reversed-mounting instruction before selecting it.View part

Honda CB750 / CB550 / CB500 / CB450 Stock Type Headlight Assembly ~ Replaces 33100-341-701

Halogen lamp, case and trim assemblyStock-style assembly lists a seven-inch halogen unit, rim/retainer, plastic case and wiring/hardware. Its CB450K application says to reuse the old headlight mounting bolts. Check those fasteners and the supports remaining on the bike.View part

Honda CB Front Brake Light Switch Sub Harness ~ Replaces 35345-319-000

Wiring for the front brake-light switchFront switch sub-harness referencing Honda 35345-319-000. Compare its intended section with the actual switch and loom connections. The description supplies no full termination drawing or complete main-harness package.View part

Identify changed wiring before ordering by motorcycle year

A previous lamp, ignition or switch replacement may have altered a connector or mounting point. Compare the component now fitted with the replacement’s reference, measurements and named contents. Confirm missing connector details where necessary, rather than treating the motorcycle application as a wiring map.

Keep charging controls consistent with the battery

The lithium control specifies 14V ±0.2 and requires confirmation that this suits the battery. It excludes standard lead-acid batteries; the standard Hot Shot version excludes lithium. If changing battery type, review the charging parts already fitted as well as the version you intend to order.

Connections to check across the electrical order

What should I check when the original headlight bolts are missing?

The assembly’s CB450K instruction calls for the old mounting bolts. Establish the required attachment and replacement fasteners for the retained supports before ordering the lamp. Its general hardware list does not override that model-specific requirement.

Can a battery change affect which charging part I need?

Yes. Standard Hot Shot controls and charging kits are for lead-acid batteries; lithium versions exclude them and specify a 14V ±0.2 set point. Identify the battery and confirm its charging requirement before choosing the control or kit.

How can I check brushes when the starter was replaced?

Identify the actual motor first. The offered set is for Mitsuba two-brush starters, with 12 × 14 × 6mm brushes and one insulated plus one non-insulated lead arrangement. Compare the removed components instead of using the motorcycle year to identify the replacement motor.

Not sure which part you need?

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