1974 Honda CB450K · Electrical Buying guide

Build the repair around the equipment already fitted

The headlight plug gives a Honda reference; the coil lists primary resistance, mounting spacing and wire lengths. Starter brushes specify the motor design and supplied pair. Charging controls have battery restrictions that remain separate from lamp, ignition and starter-component compatibility.

Parts to consider

Honda CB750 / CB550 / CB500 / CB450 Headlight Plug ~ OEM Style ~ Replaces 33130-300-003

Headlight plug under its Honda referenceOEM-style lamp plug referencing 33130-300-003 for the stated CB450K application. Compare the retained lamp termination and wiring interface. The description does not supply complete terminal dimensions or identify this as an entire wiring-harness replacement.View part

Honda CB Ignition Coil ~ Replaces 30500-292-672

Coil with documented primary and lead detailsIndividually sold 12V single-output coil, 5-ohm primary, approximately 80mm mounting centres and attached wires. The plug lead is 19 inches. Compare all connector paths and the reversed-mounting instruction when replacing a beige Honda coil.View part

Honda CB Starter Motor Brush Set ~ Replaces 31201-292-158

Specified pair for a Mitsuba starterSet of two 12 × 14 × 6mm brushes for Mitsuba two-brush starters, with one insulated and one non-insulated lead arrangement. References 31201-292-158 / 31201-MG9-004. Match the motor and removed brushes before selecting the pair.View part

Keep lamp mounting work with the chosen repair scope

The stock-style headlight package lists lamp, case, trim and wiring/hardware, but its CB450K instruction requires old headlight mounting bolts. Compare the retained supports and those fasteners before choosing it. A plug-only repair has its own electrical interface and does not identify the wider structural repair.

Check battery requirements before a charging-system change

Lithium Hot Shot controls specify 14V ±0.2, subject to confirmation for the battery, and exclude standard lead-acid batteries. Standard versions are for lead-acid only. Identify the battery actually installed and choose a consistent control or rotor-kit version for that requirement.

Electrical interfaces and supplied components

What needs comparing when an aftermarket lamp was installed previously?

Identify its electrical termination and mounting separately. The OEM-style plug lists 33130-300-003 without a full terminal drawing, while the stock-style lamp assembly has a specific CB450K bolt-reuse requirement. Confirm the missing details needed by the lamp and supports now fitted.

How can I plan coil and plug-cap purchases together?

The coil is sold individually with wires attached; plug caps are separate individually sold choices. Identify the connections and electrical requirements of the ignition being retained. The coil description does not itemize a supplied cap, and neither cap listing states its resistance value.

What should I record before ordering brushes for an unidentified starter?

Establish the motor design, removed brush dimensions and insulated/non-insulated lead arrangements. The offered pair is specified for Mitsuba two-brush motors at 12 × 14 × 6mm. Confirm that identification before using the motorcycle application to select internal motor parts.

Not sure which part you need?

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