1977 Honda CB750K Handlebar Switches

The two listed 1977–78 CB750K handlebar controls have different wire-routing arrangements. The right-hand assembly routes its wiring outside the bar; the left-hand assembly requires internal routing and has a locator pin. Check both the existing control and the handlebars before choosing a replacement.

1977 Honda CB750K · Handlebar Switches Buying guide

Check each control’s routing against the handlebars

Choose the brake-side or clutch-side control by its application and wire route. This matters particularly on replacement handlebars, where an externally wired right switch does not establish that the left switch will install the same way.

Check replacement bars before buying the left control

The left assembly’s description requires the wires to run inside the handlebar and notes a built-in locator pin. It also discusses bar preparation for installation. Compare your bars with those requirements and follow the product instructions rather than assuming a control will clamp onto any custom bar unchanged.

Keep other-bike installation notes in context

The right control’s listing also covers other Honda models with their own connector instructions. Its CB400F notes should not be treated as a requirement for the CB750K. Use the 1977–78 CB750K application and compare your existing plugs before planning wiring changes.

Questions about handlebar switches

Do the left and right assemblies both have external wiring?

The right-hand listing describes external wiring. The left-hand listing requires internal wiring and includes a locator pin. These differences are stated for the two featured assemblies, so compare both sides before ordering a pair for replacement handlebars.

Are these controls listed for the 1977 CB750K?

Both featured controls list the 1977–78 CB750K. The right assembly references 35130-404-671, while the left references 35200-404-671. Confirm the fitted controls and wiring if the motorcycle has been modified since manufacture.

Does the right switch require the CB400F connector modification on my CB750K?

The right assembly’s plug-removal and bullet-connector note is specifically for its CB400F application. The CB750K is a separate listed application. Compare the actual connectors and follow the instructions for your motorcycle before making any wiring alteration.
