1975 Honda CB550F · Starter & Charging Buying guide

Separate starter service from charging repairs

A starter brush set and a combined rectifier/regulator address different systems. Check the installed starter construction for brushes, then identify battery chemistry and mounting requirements before choosing a charging unit.

Check the motor before ordering brushes

The featured pair is for a Mitsuba two-brush starter and contains one insulated-lead brush and one non-insulated-lead brush. Compare the fitted motor and the stated brush dimensions before ordering. A solenoid fault or damaged cable needs a different repair from worn starter brushes.

Battery chemistry decides the regulator choice

The lithium-only unit has a 14 V ± 0.2 V set point and must be checked against the battery manufacturer’s requirements. It is not for a standard lead-acid battery. Both combined units may need custom mounting; plan the location and clearance while preserving the motorcycle’s starter safety circuit.

Buying questions

Does the brush set include both brush types?

Yes. It contains two 12 × 14 × 6 mm brushes: one with insulated leads and one with non-insulated leads. Confirm the installed motor is the specified Mitsuba two-brush type before choosing the set.

Which regulator should I choose for a lithium battery?

The lithium-only option uses a 14 V ± 0.2 V set point. Compare that value with your battery manufacturer’s charging requirements before selecting it. Its lithium label does not establish suitability for every battery sold as lithium.

Will the combined regulator use the original mounting without changes?

Custom mounting may be required. Compare the unit’s dimensions, 80 mm mounting centres, plugs and available space before ordering. Follow the product instructions and retain the starter safety circuit when planning the revised location.

Not sure which part you need?

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