1970 Honda CB450K · Electrical Buying guide

Match the connection and the application of each part

The ignition switch specifies a round connector. The left bar switch specifies externally routed wiring. Charging products distinguish lead-acid from lithium-ion use. These details let you choose the appropriate component without assuming that one electrical purchase covers the surrounding installation.

Parts to consider

Honda CB Ignition Switch ~ Replaces 35100-303-007 Ignition switch with round plugRound six-hole, four-wire ignition switch, including Honda references 35100-303-007 / 35100-292-003 / 35100-292-013. Listed for the 1970 CB450K with a round harness connector; check the fitted plug.View part Honda CB Bar Switch Assembly ~ Left (Clutch) Side ~ Replaces 35250-300-033 Black left-side bar switch assemblyClutch-side switch assembly referencing Honda 35250-300-033. Its description explicitly routes the wiring outside the handlebar. Match the housing, wiring connection and routing to the installation you intend to retain.View part Honda CB Hot Shot Rectifier / Regulator ~ Replaces 31400-292-670 Charging control for a lead-acid batteryHot Shot combination rectifier/regulator intended for the existing stator and standard lead-acid batteries. Lithium-ion use is excluded. Compare the retained connections and installation before selecting this control.View part

Check supporting parts against the actual assembly

The front stop-switch sub-harness, starter battery cable and fork reflector each have separate product references. Match them to the component being repaired and inspect the retained attachment or wiring. A cable, switch or reflector name alone does not define every dimension needed for an altered motorcycle.

Carry the battery restriction into the complete order

Lead-acid and lithium charging versions have different stated battery applications. The lithium products specify 14V ±0.2, which needs confirmation against the battery manufacturer’s requirements. Choose the battery-compatible version whether buying a standalone control or a rotor and control kit.

Planning an electrical parts order

Which wiring route does the left bar switch specify?

The description says its wiring runs outside the handlebar. Compare that route with your handlebar and harness before ordering, especially if the current wires run internally. The description does not establish an internal-wiring conversion.

Can a matching coil bracket settle the ignition choice?

Check the electrical and lead specifications too. The coil is a 12V single-output unit with a 5-ohm primary and attached wires. Its mounting centres are approximately 80mm; compare those alongside the wiring and lead routing of the ignition fitted.

Does the lithium charging version suit every lithium battery?

The lithium products give a 14V ±0.2 set point and exclude standard lead-acid batteries. Confirm the specified set point with your lithium battery manufacturer before choosing the unit. The motorcycle application cannot answer that battery-specific requirement.

Not sure which part you need?

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