Review on Hella 002768821: Powerful Black Disc Horn Kit (24V), Universal Fit by Jerry Chembola

I was trying to replace the standard horn on a KTM 790 Adv R with a louder horn. The first attempt was a Fiamm horn, which was very loud until just a few drops of water hit it. I settled on a "disk" type horn, which should be waterproof. This horn is very loud, much louder than the original. My only issue was that the mounting screw on the horn was very short and I couldn't use it with the stock mount. I was able to install the horn by drilling a hole in the supplied bracket and then attaching the motorcycle bearing bracket to the supplied bracket with a screw. Very happy with the purchase.
