Topic: Decent replacement horns

[toomanybikes]

Seems like both horns on my '78 750F are toast. Running 12v directly from a battery does nothing.

Most of the horns on Amazon are now super cheap, small, and have the connectors in the wrong orientation with no way to rotate the mounting tab.

Are there any aftermarket replacement horns that are roughly the same size and will work with the existing mounting bracket and wiring? Looking on ebay, Honda seems to have used the same horn with the '90's CB750 as well.

You get what you pay for, most China parts are junk

Sometimes moisture gets in there and the diaphragm gets stuck.
The earlier horns could be taken apart but that one looks crimped.
That screw is is sort of a volume adjustment. You might try running it in and out a couple of times. It might unstick the horn. Might.

Says sold out but these may work. Japan is on holiday now but might be worth checking

Wow, $240 for a pair of horns! I like keeping it original, but not at that cost.

My CB750 K6 got dual snail horn for safety. They wake up bad car drivers.

Cheap chinese stuff still working after 10 years. A relay is needed.  Bike parked in warm dry garage when not ridden.
Something like these

Voxbell horns are a true classic and were standard in the 50s and 60s on many Lancia's and Alfa Romeo's. Moto Guzzi also had them. It has a wonderful sound (115dB). I would describe the sound as 'class and distinction'. The set draws 10A, so you need a relay and a separate 15A fuse. When I bought them, they were quite cheap. They have this nice sound you would hear on Alpine roads back then. Looks nice too. They were quite easy to fit once I had bent two brackets myself. They are a joy and I feel safer.

Thanks all. I'm going to give these a try https://www.amazon.com/dp/B0CM42KP49?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

Benefits are:
1. Same diameter as OWM
2. Mounting tab is bolt on in rear, so I'll be able to rotate or replace wit the OEM tab to get proper position. I'll post a pic if they are successful

I prolly have an OEM spare if you want to go that route.

Thanks, I'll let you know how the aftermarket ones work out.

For posterity, these Neoget horns seem to be decent replacements. The mounting tabs are the right size and can be rotated to the best position. The connectors can be bent to a decent position and didn't snap. They fit with the existing plastic parts, etc. They are a little deeper than OEM, so they stick out a little further, but it's OK. A two-pack is under $20 on Amazon, at the moment.
