Horn sound

[ukjules]

It's taken me years and years to even remember to ask this question. I want a better horn sound on both my GS550 and GSX250.

So design criteria is: same fittings as standard (one single bolt to frame and one horn) and a deep blast of a horn sound.

Why? There are occasions when you wanna press the horn. I recently had an idiot van reversing almost into my GSX250 and the horn was not man enough to warn the driver.
And
The high pitch bleep of the original is not fitting for my bikes anymore.

My stock horns (11E) have screws that adjust the sound. You might want to tinker with yours.

Most aftermarket motorcycle horns are a one bolt design.

Maybe read up on the current loud horns, there's some fun ones out there.

Been there, van reversing up a steep hill at me from close range and nowhere to go although I had put myself in one of his blind spots.
There were two on the 850 a hi and lo notes.
Current ride needed a new one and I ended up with a generic aftermarket hi note.
It has the CE approved for bikes label and is loud enough to hurt at close range.
I seem to recall something about higher frequencies being more easily heard by more of the population.
That said I almost never use the horn. As the wildlife gurus say, never startle an animal of limited intelligence, you never know how they will react

If you happen to go with an aftermarket unit, be aware that it might have one or two electrical terminals. Your stock horn has two, so that would be a simple change. If your new horn has a single terminal, use your stock wires to trigger a relay. Run a (fused) wire from the battery to the input of the relay and a new wire to the single terminal on the horn. Use at least 14 gauge wire.

I have a pair of Bosch Peasant Warmers, fed via relay.
They work.

The Horns on my Motor Horn are air powered, and they are the loudest horns I have ever head. They look like miniature Trombone ends, one bigger than the other to get the two tones, and a big fan motor that pumps the air.

a lot to think about .
a) Ill try and adjust and see what the original can produce.
b) no good then it's look into all your answers. I need a good
phraarrrphhh sound ..,..
(this weekend it's fork seal / reasemble stripped and cleaned up rear brake
calipers / " horn".)

Plenty of loud horns out there, like the links show. Problem is, it's hard to find them that fit in an inconspicuous space, as the OEM's & don't look out of place. Also adjusting the OEM's can make a big difference. Hope it does for you.

There's a set screw on some. I can't recall but its for adjustments. Mine had a clear varnish as a thread locker which failed requiring adjustment and relock.
a relay on the circuit would help oem is a oddly fine wire.
also clean and polish the handlebar switch.
