So, the other day my horn fell off. Somehow the bolt came loose and I heard the horn dragging on the ground. Luckily the wires held on, and the horn still works after a couple of miles on the freeway. The bolt being missing, I can't bring the whole bike into the hardware store to match up bolt size/ thread pattern. I was just wondering if anybody knows off hand what size bolt I need to reattach the horn, before I go in and blow 5 bucks on different sized bolts to find out

My OEM horn has the bolt stud attached to it, no way to fall off.
Were you talking about the nut instead?

I replaced that horn with the Denali Soundbomb Mini.
It looks like it might be an M5 x 0.8
Sorry. Forget that size, realized I have some screws/bolts that size and the nut is larger.

Awesome. Thanks for the info. How do you like the Denali?

Definite improvement over OEM! Although I’m sure it still pales in comparison to their airhorn version.

My install didn’t go without a hitch however, tested OK at first and then failed to make a sound on the first ride.
I had to remove it and use the adjustment screw until I got it making a sound again. Been perfectly OK ever since. No idea what happened.
