Yes - loud - so go Denali Soundbomb Air Horn.I'm talking about hose yellow horns, that is the ones I removed and replaced with an air horn.
The Madstad windshield seems to be the go-to for better wind protection. I added a bracket to raise my windshield but, that didn't help much so then I added one of those clip-on toppers that adds another 3 inches and that helped with the buffeting noise. When my X300 was stock I was getting a lot of noise in my full-face helmet. I am convinced the Madstad is the way to go. The price is a bit steep, but it is what it is.Very happy with the Bad Boy air horn I now have. The shield is a Madstad.
Ah HA an X300--Photos will get your a free ticket to the technical how to forumIt is mounted in the stock location; the Bad Boy is bigger but not by a lot. It has the compressor and horn built together, all I did was used a small bracket as an extension of the stock bracket to move it a little lower and another bracket to firm up the mount to another bolt on the cowling. I will try and get a picture if it ever warms up here and I can get the bikes out.
