Choose a 1981 CB650C handlebar switch by side, connector arrangement and the controls actually installed. Both selected assemblies route their wiring outside the handlebar. That matters when comparing a modified loom or handlebars that place the switches farther from their original positions.
1981 Honda CB650C Custom · Left & Right Bar Switches Buying guide
Compare the two switch harnesses before buying either side
The left clutch-side and right brake-side assemblies have separate functions and references. Trace those functions with the wiring diagram and check the mounting before assuming a similar connector makes a replacement compatible.
The product descriptions specify wiring outside the handlebar for both assemblies. Compare cable reach and mounting with the actual bar and controls. A route that pulls or pinches during steering needs correction; do not rely on model identity to verify modified cockpit dimensions.
Use circuit function to match connections
The two sides have different jobs and harnesses. Compare the correct product instructions and motorcycle diagram before connection. Record previous splices and changed plugs so a replacement switch is not connected by color alone to an unknown modified circuit.
Left & Right Bar Switches questions
Are left and right assemblies sold as one package?
They are separate product entries. Select the side being repaired, or order both only after matching each assembly’s mount and electrical connections.
Are these intended for internally routed handlebar wiring?
The selected products are described with wiring outside the bar. Compare that arrangement with the motorcycle and any custom handlebar before ordering.
What if my old plugs have been replaced?
Map the circuit functions using the proper wiring diagram and compare the replacement harness. A changed connector requires deliberate electrical matching rather than assuming the original plug layout survives.
