Easy to install., the hardest part was getting the cover off my battery and putting the hard wire back on the positive battery terminal as the bolt wasn't long enough , but I got it.It is very loud. Not crazy crazy loud and not quiet lol. Perfect level of volume just enough to get people's attention where they stop in their tracks. Worth the money.

Start to finish install 1:20 including putting it up on the lift. Only comment is the manufacturer should have put the fused wire on the inside of main horn frame (there's a hole too) to make the battery wire guided further away from the engine heat. Otherwise, sound is very loud but not obnoxious. My '14 H-D Limited horn was sounding muffled and often felt like it wasn't heard. This baby should change that quickly. Very pleased, recommended. Made in Italy for what it's worth.

First off this is not a plug and play like the box says or the Harley dealership said, you have to fish a hot wire to the positive terminal on the battery which is no big deal. It fit my HD 08 Ultra and is extremely loud, just what I was looking for, sounds like a fire truck. It looks great on the bike. Some Harley Davidson dealerships are selling this, they would not come off there $249 price so Amazon at $219 was a great price and had it next day.

Excellent product, easy to install, definitely loud! Why the cheap plastic easy-to-scratch plastic housing? For that price we should expect painted metal.

Just what I was looking for. This is very loud and will get drivers attention. I actually made some friends jump at a stop on a ride when they were not expecting the horn to sound. Looks great and easy to install. Stock wires plug in, just need to run the third wire to the battery.

This horn is pricey but it’s very loud and pretty. It looks pretty good on my SGS and was easy to install.
