I did get to this thread a year after the original post, but I would like to thank you for a great find.I changed the wimpy horn on my 1250GSA a while back and it turns out, it was the same OEM horn on the R18. There is a "plug & play" BMW car horn that fits perfectly and is louder and deeper. The part is: Clarton Horn P/N: CN-61338381271
