1978 Honda CB750A · Horns & Buttons Buying guide

Separate the control button from the horn assembly

The button is a small control component, while the custom horn supplies the sounder and bracket. The custom description changes the mounting position to the frame centreline, so compare that layout with the installed arrangement.

Choose button repair by the small component needed

The button description supplies a spring and permits horn or starter use, but it does not name a complete switch housing or wiring assembly as contents. Match the component to the fitted control. A button replacement and a new horn are separate purchases, even when both relate to the same control function.

Review the custom mounting position before choosing the horn

The Joker Machine description places the horn on the frame centreline instead of the stock horn’s offset position. It lists a bracket and two gold screws. Compare that stated layout with the motorcycle’s actual mounting space and existing equipment; the product name does not establish unchanged stock positioning or electrical connection details.

Common questions

Is the button supplied with a complete horn?

The button listing describes a button with its spring, usable for horn or starter control. It does not list a horn sounder. The custom horn assembly is a separate product with its own bracket and mounting-screw contents.

What pieces are listed with the custom horn?

The Joker Machine horn description includes the small custom black horn, a CNC-machined bracket and two gold mounting screws. Compare those contents with the mounting work planned; the listing does not describe the small control button as supplied with that assembly.

Does the custom horn retain the described stock position?

Its description says the horn relocates to the frame centreline instead of the stock horn’s offset position. Treat that as a custom mounting choice and compare the actual motorcycle’s arrangement before ordering, without assuming the existing location remains unchanged.
