Federal regulations state that your bike should be equipped with a horn. They are installed on all factory motorcycles, but on custom bikes? Huh, huh. I know your argument (and mine). When riding, nobody will hear your horn anyway. Loud pipes save lives….Right? But if you want a better looking horn than the factory "bel"l (why it continues to be so ugly), or obliged to have one to be able to title your bike or whatever reason, you can use this chrome mini horn (at 2 1/2" it’s the smallest in the world) that you can dress with a choice of 3 different covers.
