I just upgraded my old 1977 Suzuki horn to two FIAMM horns from princess auto (high & low tone) so now instead of meeep meep I get freaking railway train horn. Gotta be the best $18.00 X 2 I have spent on my restoration. Installed last night, already saved my bacon this morning as some guy in an suv decided my lane should be his. Can't understand why on current model bikes most of the horns are so pathetic.
