Horn Upgrade?

Just got my '17 1200GSA yesterday and took it out for a spin this PM. In checking out everything I could think of, I discovered that the the horn sounds like one of Little Bo Peep's lost sheep. What recommendations for a horn that would wake the dead or stir the cell phone texter? Thanks, JD

I've got a Denali sitting on my workbench and will probably make it a winter project to install it on it's own dedicated circuit off my PDM60 or a separate automotive style relay. There are lots of "how to's" around on the installation.

I've got the Stebil version of this same horn installed on my KLR and it's capable of causing bowel evacuations in nearby offenders.

I fitted my soundbomb about six weeks ago, and other than a quick test had no reason / occasion to use the horn until the other day.

Going down a road in a 30 mph area, I approach a section with a T junction joining the road (i.e. I have right of way). As I approach, there’s a car wanting to turn into the junction from the road I’m on, so I have my eyes on that car, whilst there’s also a large van looking to come out of the junction so I also have my eyes on that as well.

The guy in the large van slows down to an almost stop about 3 yards from the junction but has his eyes and left arm on the passenger seat, sorting something out. He doesn’t stop though and suddenly moves forward over the remaining 3 yards. I have no idea if he’s moving out or not.

Hit the horn. His head spun round like Linda Blair in the Exorcist, a dropped mouth and his eyes wide open!

All happened in a moment, I could then return my eyes on the car wanting to turn in - he’s staying put, great, on I travel on without breaking speed.

Now, I’ve no idea if van man would have pulled out. But it was a moment that brought home to me the reason why changing your horn should be among the first of the mods you do to a bike: loud horns probably save lives.

If you buy the ridiculously overpriced canbus connector for bmws that Denali supply then, as others have said, the Denali is an easy plug and play fit. Denali also sell a bracket for the GS for fitting the standard soundbomb between the forks (though it needs to be at about a 20 degree angle to ensure fork clearance).

I have found that I use my upgraded horn most often when on the interstate to stop cars from coming into my lane. If they are accelerating to merge it is easy to get into their blind spots. If I still had the stock horn, I know they would never hear it. Always thought the GS had meep meep horns so the sheep in the road when doing adventures in the Andes wouldn't stampede when you need to get past them. All the BMW's seem to have terrible stock horns now. My 2003 RT had a real horn as stock but it had a real tool kit with it too!

SoundBomb installation is very easy if you use an ezCAN. No relay or trigger wire required, no tapping into the wiring harness, old horn stays in place and is functional, and both horns are controlled by the horn button. If you so desire you can have your non-OEM auxiliary lites flash when the horn is used.

Denali : regular or split?

2 models are available: the regular one and the split one (2 part) ... Which one for my 2016?

Thanks

ezCAN is a device that allows you integrate accessories into the motorcycle’s electrical system (CANBus). It allows you to use the existing switches to things like auxiliary lights, horn and heated gear. It requires no splicing or tapping into the bike’s wiring harness. It replaces things such as fuse blocks and power distribution units and greatly reduces the number of wires needed since relays and on/off switches are not required. It is the cat’s pajamas.

Pterodactyl -

Twisted Throttle now has an updated "SmartCan" version of the HexCan. I think they both do the same thing, the Smart Can just has a much simplified install, for which they charge a premium. For Example, no ballast on the horn or lights, for the post above. The supplied wiring has really good quality connectors on both ends, no fuss fitting the SmartCan. You do have to use splicing to fit the rear modulating tail light, I'll shrink wrap it. The battery rings are even preattached. The hangers for the Denali D-4 lights and Soundbomb are nice powdercoated steel.

Bottom Line - You Trade Cash for Saved Time and a Cleaner Install.

CANsmart and HexCAN, IIRC, are both developed and made by the same group in SA that produce the GS-911. The CANSmart was offered for the Denali light system.

In my application of aux lights, horn and two other low amp draw accessories the HexCAN works flawlessly and a massive improvement over my previous experience with conventional fuse blocks.

At the risk of being a spoiler, I received a Denali Soundbomb for Christmas from my sister-in-law. It died in less than a year. I contacted Denali and they wouldn't honor their warranty without the original purchase receipt, which she no longer had. I have a friend who had a similar experience with the Soundbomb. So, I won't buy from Denali again. Just my $ .02 worth.

In California I never bother using my horn since the other driver interprets it as you see them and will avoid letting them hit you.
I've had people change lanes on the highway into me while I was on the horn and they were looking out the side window right at me the entire time and just kept coming.
If anything I want a horn that is about half as loud as the stock unit, so I can use it to alert a driver that's texting that the light has turned green, but I don't want to upset them with a loud horn and get shot.

Air horn?

I have an air horn, but I am a little ambivalent about it. It is so loud that I am afraid to use it in traffic because I think it will startle people and perhaps cause them to do something dangerously erratic. It definitely makes people jump and is really quite annoyingly loud. I think if I did it again I might consider one of the louder electric options that could be used with the existing mounts and wiring. I wish I could select which horn to use (I left the factory horn in the circuit.)

I was hoping that the loud horn would deter animals (deer, cattle, etc) that I might see on the road far in front of me, but though it gets their attention, they just stare at me, then only scatter as I get very close.

Most people on GSs seem to use the Denali Sound bomb, but I'm not a fan due to the size. I installed a set of Hella hi/low horns purchased on Amazon for $25. They are compact and easliy mounted them up under my beak using my running light brackets. They come with the same femaie connector socket as the original horn so the connections remains water tight.

I wanted the wiring to look and function as if original equipment, so... I went to a local dismantler, took one of the horns with me and found that the pigtails from a Mini Cooper use the same male connector, $2 later they were mine. I clipped the original single connection, grafted my new pair of connectors with the appropriate length wiring to each horn and they work flawlessly. I programmed my Ezhex to flash my Clearwaters when I use the horn, very pleased with the volume and no issues.

Ditto. It's a cheap and easy improvement on the horn BMW stupidly and unforgivably supplied with the GS/GSA, sounding more like a choir boys wet flatulence than a device to wake the odd blind and asleep 4 wheeler.

That said it still isn't a patch on the 2018 K1600 GTL OEM horns which are superb and put the fear of Christ up the occasional dozy donkey. And so I'll be installing a Denali Sound Bomb this winter (sadly the GTL horns don't fit my GSA) with a set of Denali D3 lights to again ward of Kamikaze 4 wheelers and friends. If the lights don't wake em up a combination of strobing lights and a horn from the SS United States will ;-)
