1972 Honda CL450K5 · Starter & Charging Parts Buying guide

Separate charging choice from starter repair scope

The combined regulators have opposing battery restrictions. A separate rectifier and starter terminal cover address other needs, while linked brush and rotor-kit products require their own equipment and contents checks.

Choose the charging package deliberately

The standard combined regulator and linked rotor-plus-regulator kit are for lead-acid batteries only. The featured lithium-ion unit instead excludes lead-acid batteries and specifies 14 V ±0.2 V, subject to battery-manufacturer confirmation. After resolving the battery requirement, compare the actual harness connections and mounting arrangement.

Identify the starter before buying brushes

The linked brush set is for Mitsuba two-brush starters and contains two 12 × 14 × 6 mm brushes, one with insulated leads and one with non-insulated leads. Compare the starter fitted to the bike. Its external terminal boot is a separate protective component, not an internal repair kit.

Buying questions

Does the linked charging kit include a replacement stator?

Its stated contents are a rotor and combination rectifier/regulator; the description anticipates retaining the existing stator if serviceable. Establish that stator’s condition and exact application before assuming the kit covers every charging-system repair.

Can the lithium-ion unit be chosen before selecting the battery?

First confirm the battery manufacturer accepts its 14 V ±0.2 V setpoint. The product is lithium-ion-only and excludes standard lead-acid use, so a planned battery change must be resolved before the regulator order.

Will any starter labeled for this model accept the linked brush set?

Identify the motor itself. The brush set specifies a Mitsuba two-brush starter and given brush dimensions; a replacement starter fitted in the past may have different internal parts despite the motorcycle retaining its model identity.
