1973 Honda CB750K Handlebar Switches

The 1973 CB750K handlebar switch selection has separate left and right assemblies. Both are listed in black, but their wiring routes differ: the left listing runs inside the handlebar and the right listing outside. Check your bars and existing controls before ordering.

1973 Honda CB750K · Handlebar Switches Buying guide

Match the side and the wiring route

The left assembly serves the clutch side; the right serves the brake side and includes the side OFF/ON switch. Compare the actual handlebar and harness arrangement before selecting the assembly you need.

Account for the two wiring routes

The two assemblies are not described with the same cable routing. The left product specifies wiring inside the handlebar, while the right product specifies wiring outside it. Compare those details with the bars installed on your motorcycle, particularly where the controls or handlebars have been changed.

Use the application note for the right assembly

The right switch description names the 1973–75 CB750K as its direct-fit application and includes a side OFF/ON switch. Its notes for other models explain additional differences, but those are not instructions to modify a 1973 bike. Compare the listed assembly with the right-side control you intend to replace.

Common questions

Which assembly belongs on the left side?

The left assembly is labelled the clutch-side switch and is listed for the 1973–76 CB750K. Its description specifies wiring inside the handlebar. Compare that route with your fitted bars and the switch being replaced.

Does the right assembly use external wiring?

Yes. The right brake-side product explicitly says the wiring runs outside the handlebar. It also lists the 1973–75 CB750K as a direct-fit application. Confirm that this agrees with the motorcycle’s current control and wiring arrangement.

Is the side OFF/ON switch included on the right assembly?

The right assembly’s description includes the side OFF/ON switch. That is part of the listed assembly, not a separate selectable variant. Review its photographs and control layout alongside your existing switch before completing the order.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
