1971 Honda CL450K4 · Starter & Charging Parts Buying guide

Choose the charging component after identifying the battery

The offered combined units separate standard lead-acid and lithium-ion use. The linked kits also include a rotor, while the linked brush set applies to a specified two-brush starter arrangement.

Keep the two battery versions distinct

The lead-acid combination unit and lead-acid rotor kit exclude lithium-ion batteries. The lithium versions exclude standard lead-acid batteries and specify a 14 V ±0.2 V setpoint. Obtain the lithium battery maker’s confirmation that this setpoint is suitable before choosing either lithium product.

Check what the larger kit adds

Each linked charging kit contains a rotor plus a combination rectifier/regulator and is described for use with the existing stator if serviceable. The brush set instead contains two 12 × 14 × 6 mm brushes, one with insulated and one with non-insulated leads, for Mitsuba two-brush starters.

Buying questions

Does the separate combined rectifier/regulator include a new rotor?

The rotor is explicitly included in the linked charging kits. The separately featured combined units are distinct products, so choose the kit only when the repair calls for its stated rotor-and-regulator contents.

Is a 14 V lithium setpoint automatically suitable for any lithium battery?

No. The lithium product descriptions require confirmation against the battery’s charging requirements. Ask the battery manufacturer about the stated 14 V ±0.2 V setpoint before selecting a lithium charging unit or kit.

Can the starter brushes be chosen from the motorcycle model alone?

Check the motor itself. The linked set specifies a Mitsuba two-brush starter, 12 × 14 × 6 mm brushes and different insulated/non-insulated leads; compare those details if the starter has been replaced.

Not sure which part you need?
