That Airhorn mounted out in the wind will gather bugs like they were good eatin.
RJ, I have to respectfully disagree. I've got the rivco air horns mounted on the crash bars on all my bikes and have never had any problem with bugs getting in them. Those covers do a good job. The covers have alot of bugs on them but the horn seems to stay clean. I've got over 100k on one and the horns work fine.
I mounted mine using a combination of the Rivco bracket, a chrome L bracket and a chrome bar clamp.


Mr Hook, Sir. Those covers are nice, but everytime I went on a road trip, someone stole them off of the bike at night, and NO, I was not in the bad part of town.
I was at a Bob Evans eating and the waitress came over and asked if that was my bike, told her yes and she said those guys took something off of your bike. Looked deeper and saw the horn covers were gone. Da Police couldn't of been of any help, but we called them anyway. They came and asked if I could identify them? Said, sorry I hadn't engraved them yet. They gave me a case # and took off.
