Frequently Asked Questions

Which Honda headlight-reflector bolt does this replace?

It replaces Honda OEM 90120-377-000 at the headlight-stay or front-reflector mounting location on the compatible CB750, CB550, CB500 and CB400 models shown.

How many 90120-377-000 reflector bolts are included and required?

One bolt is included. The listed left-and-right reflector arrangement uses two per motorcycle, so two are required when replacing both sides.

What should be compared before installing the reflector bolt?

Match thread diameter, pitch, shoulder or unthreaded length and the original washer or rubber-base arrangement. Tighten it only enough to secure the reflector without crushing the rubber or damaging the bracket.
