1972 Honda CB450K · Starter & Charging System Buying guide

Compare a single circuit component with a rotor-and-control kit

The solenoid references Honda 35850-375-000 / 35850-286-027. The separate rectifier specifies a female connector. Hot Shot controls and rotor kits distinguish lead-acid from lithium-ion batteries; the rotor kits include a new rotor and combination control with the existing stator retained unless it tests bad.

Parts to consider

Honda CB Starter Solenoid Relay ~ Replaces 35850-375-000 Replacement starter solenoid relaySolenoid referencing Honda 35850-375-000 / 35850-286-027 and listed for the 1972 CB450K. Compare mounting and retained circuit connections.

Choose the battery version before the repair package

The standard controls and kit exclude lithium-ion batteries. Lithium versions exclude standard lead-acid use and specify 14V ±0.2, requiring confirmation against the battery manufacturer’s requirements. Apply that choice whether buying a control alone or a rotor kit; neither package removes the battery-specific check.

Review starter service parts at their actual locations

The brush set names Mitsuba two-brush starters and two 12 × 14 × 6mm pieces with different lead insulation. The terminal boot references 32411-230-000, and the starter seal has separate references with a 60 × 1.4 size label. Match each component directly rather than treating them as a complete starter rebuild kit.

Comparing starting and charging repair scopes

Does the rotor kit replace the existing stator as well?

Both kit descriptions itemize a rotor and combination rectifier/regulator, and state use of the existing stator unless it tests bad. A new stator is not listed as supplied. Assess the stator retained on the motorcycle before deciding what additional repair components are required.

What specifications matter when fitting the lithium control in a tight space?

Its stated dimensions are 54mm length, 57mm width and 35mm height. Compare the mounting and available space alongside wiring connections. It is lithium-only with 14V ±0.2 set point, which also needs confirmation for the battery; physical clearance does not settle that requirement.

Does the solenoid listing confirm every terminal detail for changed wiring?

It gives the replacement references and application without a complete terminal or mounting drawing. Compare the retained attachments and circuit connections, then confirm missing dimensions required by altered wiring. The model application cannot identify every solenoid connection used during previous modifications.
