The twin Stebel horns that came on the R75 are much louder than stock. They are a common upgrade for many bikes as a safety enhancement. Loud horns probably do save lives. However, the horns were mounted outboard on the down tubes which probably made them even more effective, but which made them a prominent visual element as well. Not to my liking, and since the bike is not to be a daily driver, not as critical for safety.
I had a modern 12v horn in the stash, which is also louder than stock. However, it also looked out of place. I settled on another chrome horn from the stash which looked much more stock, but sounds much more stock too. I removed the relay and wiring for the Stebel and returned to stock wiring to the horn. Looks good. Job done.
