Sweet!! I finally got around to installing this thing on my R1200GSA LC... For a clean install I took some of the plastic down and actually replaced the original horn.. no splicing, I ordered a pigtail that fits right into the original horn wiring and made a clean mess of the wires. (part is called Horn wiring kit for BMW bikes with Can-Bus wiring from Nippy Normans.com) I also separated the compressor from the horn it's self and was able to mount the compressor with a home made bracket to the original horn mount, the horn it's self snaps right onto the front suspension remote reservoir or one of the down tubes (if you're not worried about clearance). With all the plastic back on the bike, no one will know.... until their ears hear the train that is me bearing down on them!!
Wiring on the BMW R1200GSA LC is as such:
Relay terminal 87 to + on compressor
Relay terminal 85 to Brown OEM horn lead
Relay terminal 86 to Green OEM horn lead
Relay terminal 30 to + on battery
Great, loud horn. I ride a vintage Kawasaki that does not have loud pipes. Since a large percentage of MC accidents happen at intersections I cover the horn button when approaching. I have had to warn a couple to see the invisible - a bike headed their way.
It does not work when the bike has been sitting. I think it must draw enough more amps that the bike needs to be running and the battery fully charged. (Posted on 6/28/14)
like most everyone else, I found this thing to be VERY LOUD! a great safety device on a bike, I've already scared the hell out of 2 braindead wandering cagers in the 1st week. easy to install with the wiring kit. I also bought one of these horns for my car and it's just as effective. well worth the money. (Posted on 6/4/14)
Instructions and owners guides for many products can be downloaded from the Aerostich website at: www.aerostich.com/catalog-pdfs - the horn instructions can be directly found at this link: http://tank.aerostich.com/pdf/prod_guides/3830_3831_3837_Horns_rev0608.pdf (Posted on 6/2/14)
I think it is -- the last one I bought and installed sure was. So when my wife got a new car with a horn about as loud as a mouse's whisper I ordered this Cannon. Pleased as punch I was the day that I came up with an excuse for her to take my truck and leave the car with me, at the house, so I could install the horn when she wasn't around to ask what I was doing. But when I opened the package I found the horn, the wires and relay -- but no instructions. I can figure out the horn's + and - , but how about helping with a "pin-out" of the relay so I'd know which wire goes where? If it's in the package - it's well-hidden. Her car is still mewling and whispering but certainly not startling any but the most timid. What do I need to do to be told which goes where? Thanks. (Posted on 5/28/14)
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)
