1972 Honda CL450K5 · Signals & Reflector Parts Buying guide

Check each lighting mount and sealing surface

Compare the installed housing before choosing its gasket, and check the reflector’s 6 mm thread separately from its rubber base. For a rear stay, identify the bracket shape and mounting details first.

Identify the lamp before ordering its gasket

The signal gasket uses reference 33443-268-671 and is associated with a particular lens and lamp family. Compare the housing and seating outline on the bike. Replacement signals installed in the past may need a different gasket even when their outside appearance is similar.

Treat reflector and stay mounts individually

The screw-on reflector has a stated 6 mm thread; its rubber base is a separate product with reference 33743-341-670. The linked rear stay is sold individually. Those facts establish different purchase checks, not a combined mounting kit or a guaranteed match for altered brackets.

Buying questions

Does the 6 mm reflector thread establish its thread pitch too?

The current description specifies 6 mm without a pitch value. Confirm the complete thread match at the installed mounting point rather than supplying a pitch by assumption or forcing a similar-looking fitting.

Can I choose the gasket from the turn signal’s outer shape alone?

Compare the lens seating edge and housing as well as appearance. An aftermarket or substituted lamp may look similar while using a different gasket; identify the actual assembly before purchasing the sealing piece.

Is the linked rear stay supplied as a left-and-right set?

It is sold individually, and the product asks buyers to confirm shape, side and mounting details. Inspect the supports on the bike and order only the verified quantity for the positions being repaired.
