I bought one of these about a couple of years ago. It has saved my life more than once. I commute daily on the freeways in northern California and split lanes. When someone tries to encroach on you this horn will DEFINITELY MOVE THEM BACK! Instead of the wimpy stock horn that caused people to look around for that annoying squeak, this thing draws their attention, snaps them into consciousness and has them looking for the 18 wheeler!
I lost the first one and ordered a second. The intervening week was shear terror for me without the protection the horn affords. YOU must get this thing for your safety.
Note, on the latest one, I epoxied the bolt to the braket so that it cannot vibrate/slide out. I mounted it on my Triumph Scrambler on the original horn bracket, just skewed to the side a bit. (Posted on 8/19/13)
Purchased a couple of months ago. Sourced another company's horn/headlight modulator but went with Aerostich horn due to Aerostich's reutation for only selling quality products and great custormer service - a thing's only as good as the folks selling it. Anyway, had modulator and horn professionally installed as my BMW R1200ST made placement tricky. My mechanic found a spot underfairing on one side. The horn is freaking loud. Use with proper discretion. Tip: In a higher-risk-than-usual traffic environment, know how to get your thumb to that horn buttion fast without fumbling. Practice if you have to Those reaction fractions will - along with a kitten-crapping loud horn - will make the difference! (Posted on 8/8/13)
I had one of these on my 2007 Honda Shadow 750, but where I initially mounted it, there was some contact between the horn and the back of the front fender on hard stops. Eventually, the trumpet piece fell off somewhere on my commute. When I got a replacement a couple weeks ago, I mounted it on the left engine guardbar, clear from any contact. Had to fabricate a bracket that I attached to a highway peg clamp - too easy. I got the replacement just in time, as I was riding that first weekend through town and had an SUV try to change lanes on top of me. The blast made him drop his cell phone and he almost overcorrected into the oncoming traffic. Now I'm working on turning the compressor from the first cannon into a portable tire inflator....

I wanted a louder-than-stock horn and this is it. It was too big to fit on my 2001 Bonneville, but I was able to disassemble it and mount the compressor under my seat and the horn on the frame without too much trouble, see description here:

I needed a better horn for my Aprilia Futura and this seemed to be the one to order. It certainly is bigger than the stock horn, so much so that I ultimately wound up mounting it inside the fairing and aimed down at the front wheel. Having the expensive installation kit was worth the money, incidentally. Anyway, it doesn't sound so much like a diesel train or truck as it does a 1958 Cadillac. In other words, it is, literally, nice AND loud. No disappointments; money well spent. (Posted on 3/15/13)
I had this on back order for months, and i'm glad I didn't give up on it. Stebel finally got things worked out and started shipping them again and I finally got mine in January 2013.
I was able to securely mount mine to the existing horn bracket on my 2005 ZX-6R which was surprising. I thought for sure I would have to bury it under a fairing and fabricate a bracket for it. It was a tight fit though, and when the wheel is at full turn to the right, it does touch ever so slightly but not enough to cause the horn to move. But since the stock horn bracket has a bushing to allow some flex even it if touched it wouldn't be a problem. I did need to add a single bolt through the top hole of the mount part of the horn to help lock in the screw that is included and ensure that it didn't come off.
I ride my bike hard in the curves, do wheelies and even like to catch some air over the railroad tracks by my house. I haven't had a single problem with it...and even the most distracted driver hears me now. The other day at the train crossing after the train honked, I laid on the horn button and it was loud enough to get the conductor to stick his head out and look to see where it was coming from. I did it again and his head was quickly replaced by a thumbs up...
Of all of the various upgrades on my bike this is hand down my favorite. I'll be putting one on every vehicle I own from now on... (Posted on 1/28/13)
