1977 Honda CB550K Handlebar Switches

1977 Honda CB550K · Handlebar Switches Buying guide

Compare each switch side and its wire path

These are separate black left and right control assemblies. The left has a locator pin and an internal wire path; both listings provide linked instructions to review against the motorcycle’s existing arrangement.

Compare the handlebar before choosing the left side

The left switch is described with wires passing inside the handlebar and a built-in locator pin. Check the installed bar’s openings and the previous switch arrangement before ordering. A replacement or custom bar should not be assumed to provide the same wire path or locating arrangement.

Read the correct model’s wiring notes

The right switch lists outside-handlebar wiring and includes a separate connection note for the CB400F. That note is not a stated CB550K requirement. Compare your own connectors and use the linked product instructions rather than transferring a wiring modification from another model’s application.

Common buying questions

Are the left and right assemblies sold as one pair?

They are separate product listings for the clutch and brake sides. Choose the side that needs replacement, or review both individually when replacing the pair; the left and right wire paths are not described the same way.

Does the left switch use outside handlebar wiring?

Its description states that the wiring runs inside the handlebar and notes a locator pin. Compare the existing bar and wire openings before purchasing. The outside-wiring description belongs to the right brake-side assembly shown separately.

Are printed instructions included with these switches?

Both product listings provide a link to product instructions. They do not explicitly state that printed instructions are supplied in the package. Read the linked instructions before ordering and confirm anything unclear about your existing control and connector arrangement.
