    2007 R1200RT - Looking for built-in second horn lead

    Can anyone point me to the (supposed) second horn lead in the harness of my 2007 R1200RT? I would assume it’s in the same general area as the existing horn lead? I’ve done some looking, but it seems that the harness is bundled pretty tightly, and I don’t want to randomly start cutting zip ties...

    2016 R1200 RT - horn shorts out?

    Another discovery on the new-to-me 2016 R1200 RT. Yesterday a driver runs a red light in front of me (very common in the San Fran Bay area these days) and I give her a loud blast on the horn, and the horn dies after about three seconds. Didn't work again until I turned the motor off and back on...

    Two for One Quick Cheap Easy Horn Upgrade

    It is no secret the horns on these bikes are pathetic. I found a quick cheap easy solution. I bought a new pair of BMW 535 horns, HELLA 012010881 Black 12V BX Trumpet Horn Kit. The kit includes a pair of horns with one rated 400Hz and a second rated 500Hz. The set of horns on Amazon cost...

    Hella Supertone horns.. obnoxious looking but they work!

    So about two weeks ago I had an individual in a brand new white and chrome Kia SUV thingy decide that my presence on the public road could be ignored. As he proceeded to turn into the road from the side street and deciding he needed to take up the majority of my lane and over the white painted...

    Denali air horn on R1200RS - Who's done this?

    I got a Denali (Twisted Throttle) air horn for Christmas and will be installing it along with a pair of Clearwater Darla's, the Canbus, the horn switch option and a mini Billie bar for the back of the bike. I'm likely going to put the Darla's on the forks but will hook them through the horn so...

    Fuse failure, turnsignal, brakelight, horn circuit, 76 R90/6.

    It (the problem) started after the bike went dark after going over a parking lot speedbump at 4 mph. A local Airhead specialist was able to correct starting and running issue, but the fuse on the turnsignal circuit blows, some times right away, other times 200 miles into a ride. 59000 on the...

    Bosch Horn - no rivets, how does it come apart?

    Next winter project - Fix the horn.... Found many links on how to take apart the Bosch horns that are riveted together... but none for the style that I have. I've taken the nut off the back and have tried to unscrew/pry the front cover off, but it's seems to be very solid. It looks as though...

    Stebel horn update

    I've installed over 20 Stebel airhorns on mostly BMW sport bike and G/S restorations and rebuilds. From a performance perspective, you can't ask for a better life saving upgrade to a motorcycle. Easy to install and it flat out works to keep the cages from crushing you. BUT The physical design...

    K75 Mystery: horn fuse blowing. Why?

    Dear Fellow Flying Brickheads: You kindly answered some questions I had about lowering a1994 K75 I've just bought to fit my frame. So I did - got Hagon shocks installed and the forks lowered some and all that is good. Got the work done in Dubai, and then drove the bike home to Abu Dhabi -...

    Horn Relay Ground Problem

    I have a 1977 BMW R100S equipped with dual Bosch horns and a relay. The original relay had 2 #87 posts but many years ago I had to replace the relay with one that had only one #87 post. The ground post was #85 on the original relay and I used #85 on the new relay and it seemed to work. The...
