    Horn and Bracket for the 1976 R75/6 Restoration Project

    I have been making some excellent progress in the restoration of the R 75/6 that I bought 5 years ago. Plan to have it ready to feel the wind later this spring.

    When I bought it it had a Vetter Fairing and a horn and bracket that didn't look right and now I am on the hunt to find a proper setup. Does anyone have a factory picture showing the horn and bracket that could be posted here so I know what I am in the hunt for. Have looked in the BMW parts book and they show two different part #'s and styles, but no bracket.

    Rick -

    I would say, if you have some time ( ), look at the rebuild sites/links in this thread:

    http://forums.bmwmoa.org/showthread....es-with-Photos

    looking specifically at the /6 ones. Sorry, there's no specifics about how detailed the threads are, but I think you can quickly go through them to see how relevant they might be to your needs. HTH...

    Rick,

    You will find some good pictures of the bracket and horn here.

    Kurt and Brook,

    Thank you for the response, as I had not the foggiest idea what the bracket looked like, as when I bought it the old girl she was wearing a Vetter fairing and the horn bracket was attached to the oil cooling fin housing. Saw some pictures on line and I believe they were from Brooks web page, but only saw where the horn hung. Took my metal working skills into the shop and found a flat piece of 1/8" X 1" flat bar and started my bends so it looked like what I saw. It was only after getting it fitted did I see the picture Brook posted after coming to the house from the shop after dinner. Guess mine was to fancy, but I wanted to make sure I cleared the front timing cover if I have to remove it.

    The Hella horn is the one that was originally on the machine and I guess the next thing I have to do next is put a battery in her to see if she will even light up. This will be the first time around for me, but never thought twice when restoring Brits bikes. Will say a prayer when I turn the key on!

    This is what it looked like prior to installing.

    Again, Thank you to the both of you for guiding me through the world of the Airhead Unknown.

    horn mountin

    Look at the hyperlink that Brook posted. There is a REASON that BMW used several thin pieces of a 'springy' metal, to mount the horn. Some models were a bit different.
    Besides the mount vibration help, the use of the stock type multiple thin pieces will make the horn considerably louder, than a home-made single thick piece of metal.
    BMW has used a couple types of that sort of mounting, with one type having the metal pieces somewhat separated. They all work OK.

    Note that BMW has used various horns, and many look similar. Some have an adjustment, which may require a bit of touch-up as the horn gets old, wears, etc.
    The adjustment is for sound and current draw.

    I saw this response to myself awhile ago from Snowbum and really had to think about the comment.

    Fast forward, I got a shipment in from Moto-Bins from the UK with two of the BMW small thin brackets. Couldn't wait to take the bracket I fabricated, put the new ones Moto-Bins sent and I jumped when I hit the horn button. The sound was very loud, clear and crisp in comparison to the farting sound I was getting before.

    Thank you Snowbum!
