Are you considering replacing the stock horn with something louder, say like a FIAMM* High Tone Freeway Blaster Horn? I have a Freeway Blaster horn I took off my now sold Ducati Multistrada. The stock Multi horn was weak and wimpy sounding and not very loud. Comparatively, the FIAMM was much louder on the Multi.
However, I tested the Freeway Blaster against the stock Scrambler horn, and the Scrambler horn is actually more piercing and slightly louder than the FIAMM Freeway Blaster. Incidentally, they are both about the same size. I know there are other horn options, but I do not want something that does not fit in the stock location.
