I have what might be a silly question. Where is the horn located on a 1982 Honda cm450c? I know what it's supposed to look like and I have the shop manual downloaded. But for the life of me I cannot find it and I cannot find it in the shop manual.

On most Hondas of that era, the horn was located either on the front forks just below the headlight, or on the frame just below the gas tank.
I'll bet if you look in that area, you'll find it.

Press the button and follow the noise :smile:

It should be at the front of the frame, just below the steering head.

Maybe is has been removed from the bike?

Well I can't find it anywhere so they must have took it off. I didn't think to check that before I bought it but if the wires are there I can put a new one on it.
I have a friend that is a retired mechanic and an ex motorcycle rider. Maybe he can show me where it should be so, I can at least, find where to plug the wires in at.
Thanks for the response.

Do these look like the right wires?:

Is the horn button still on it? If it is, put your multimeter on those wires and hit the button. If those are the correct wires, and it does look possible, you'll see the results or lack of then. Even if it doesn't show anything on the meter it could still be the correct wires with a possible blown fuse. I don't know what else might be on that circuit so it could be possible a different horn was put on at some point as well and it too removed.

Thanks. I put a multimeter to the leads, turned on the key, pressed the button, and nothing happened. I also did an OHM reading and got nothing on that as well. So it looks like it does not have a short. I may just buy a cheap horn, try to plug it in and see if that works.
I've often heard talk about fuses on a bike. I may look in the repair manual to see where they are located. Maybe someone here could help me with that problem? Where are the fuses located on a motorcycle?
There have been a couple of times, when I wished I had a horn, to alert a four-wheeler coming out of a side road. They apparently did not see me coming because, they turned out right in front of me, or misjudged my speed. Fortunately I had enough intuition to slow down some before they turned.
So a horn may not be a big deal but a minor useful safety issue, at best.

Fuses are usually near the battery under a side cover. If there is one black wyre to the missing horn, then it grounds to the frame. If there are two wyres ( wot it looks like ) then it is grounded back to the battery. One of those wyres should go to the button, the other to a common ground.

Also, check the horn button too. If you have the old style little black horn button, those usually go bad before the horns themselves. If you do have the little black style button, and you're ordering a new horn, I'd recommend ordering a new button and spring too. They're cheap and if you plan on keeping the bike for a while, order two because the horn button is the same part number as the starter button. I think I have three or four of them in stock myself because when we were kids with little cash, we'd switch them out so we wouldn't need to use the kick starts. :)

Thanks the button is red I don't know if it is a replacement or not.

I just looked up your bike on Babbitt's Honda online. They have excellent diagrams. The wires you show in the picture are probably the horn wires because that is the location shown in the diagram. I looked up your headlight too, you have a sealed beam and it would be a easy swap for a H-4 reflector lens setup. I have posted links in your light thread.
