Horn stops working when hot - 1290R

Postby Plake » Wed Sep 14, 2016 8:38 pm

2016 SDR, 5 months old, 3k miles. Normally I don't drive in cities for any great distance but have had to twice this week. Both times the horn has completely stopped working when the temperature has reached about 93-94deg. Needed the horn a lot thanks to all of the crappy South London driving too.

Did a quick search and someone else mentioned this about 18 months ago. Anyone else noticed it happening or aware of a fix?

Bike's under warranty so let the dealer worry about it is the simple answer I guess.

Mine does the same, radiator gets hot and cooks it,rarely use it so put up with it.
Others have fitted aftermarket horns.

Mine used to do that. I just assumed it was a poor connection. Didn't worry about it since I rarely use it, not being an urban rider.
Its worked fine for some time now and reading Ic4's comment about the radiator, it occurs to me I did fit an Evotech rad guard a while back. Maybe a coincidence. Dunno..

Interesting, not just me then.

Bike'll be going in for a new tyre within a month or so and will see what the dealer says.

Mine does the same thing - quits completely when hot. I'd love to find a place to mount up a Denali Soundbomb but no place looks obvious without looking like my 1290R has grown a huge wart.

This is a new one to me - gonna try mine to see what happens.

Could it be as simple as insulating the mounts?

I think it's the fact that it sits right behind the radiator, the hot air kills the poor guy...

funny but I read this a few weeks ago but hadn't noticed it. last night was riding downtown with my wife on the back to go to dinner and it was pretty warm (around 90 degrees F). I was in some traffic and hit the horn and got nothing...

didn't try it again but it seems like I have the same issue. I'll go hit it this afternoon and see if it's working again or if it's cooked. The fan was on, oil temp was around 200 degrees F.

I instinctively revbomb instead of using my horn :twisted: ... Now I'm curious if my horn even works.

Anyone seen a good guide on how to fit a split Denali soundbomb onto the 1290R?

Bit of a disaster with the horn. Asked the dealer if they can fit a Denali Soundbomb for me. No problem, done it before they said.

Had it fitted 3 weeks ago. Had to use it that day, bloody loud which was great, but got a "General Failure" pop up that wouldn't go away along with other warning lights.

Had a look under the seat - lots of cut wires and insulating tape but nothing obviously loose. Took it back up to the dealer who called the next day to say that the ECU was "spiked" and needs replacing. They also said that in fact the Soundbomb is not compatible with the Superduke and this is what killed the ECU. Had to send up my keys for recoding.

Had a call last week to say that a new ignition switch is now needed, 7-10 day lead time... It's been 3 weeks off the road and counting. Gutting.

I'm going to say that your dealer screwed you on the install and tried to power it off the existing horn power wire. No way they should have done that with a horn that draws 18A!! It should have been installed off of a relay where the horn power wire is used for the trigger input and the horn gets it's power from a fused line to the battery. I've done this type of install on several CANBUS bikes with no problems at all.

My horn also wasn't working when the BIKE was hot, i told the bike workshop while the GT was in for its service. They checked it, and it worked. But while they had the tank off checking the air filter they moved it, but i can't see it now, but it works while the bike is hot and being ridden.

Took my bike in for it's 15000K check this past summer and tech said my horn was not working so he just swapped it out with a bike that was on the floor. Funny thing is I usually test my horn before I go for a ride and I remember it working.
My guess is that because the horn is right behind the radiator it gets quite hot and there is some expansion going on. If I remember correctly these types of horns have an adjustment screw at the back of the horn. If they are adjusted too tight you get nothing and if they are too loose you may hear a click or a very quiet or muffled horn. I used to adjust these screws on my japan bikes.
Not sure if our 1290's have the same adjustment screw. There is a black protrusion on the horn and my guess is it is a cover for the adjustment screw. May check it out this weekend.

Yeah, I've no doubt it was caused by the installation, not the horn itself. I said the bike had a CANBUS system to the tech who was going to be fitting the horn and I'm not certain he knew what that was. Anyway, the dealer aren't charging me for the repair so fair do's. Mistakes happen.

Fuk i must be blind, while washing my bike i came across the horn, in its new position, in front of the radiator, to one side. Out in the open, how could i have not seen it.

They installed a new ECU, then had to order a new ignition/key kit, then the bike "died" again soon after they managed to get it running. Apparently all of the diagnostic info is going to Austria but it now looks like its going to need a new wiring loom. Must be the installation surgery :( :( :(

KTM know this is a problem and will replace the horn under warranty. Bit pants though - if you're using your horn its probably for good reason and to have it fail on a brand new bike is unacceptable.....shouting and waving your arms around at the twat car driver about to take you out isn't going to cut it.

I went to use my horn when leaving a mates place early in the morning, i wanted to give him a curtesy toot, but no, the horn didn't work, it threw up a fault code, it was only 2 degrees, so heat wasn't a factor. a few Ks up the road i stopped, turned the bike off for 2 mins, but fault code stayed for the next 90K, then the bike was turned off for 30 mins, then when i turned ignition on, the fault code was gone. I haven't tried the horn since, i hope it works for warrant of fitness checks.
