[The Hack]

As I was changing the battery and had raised the petrol tank, I thought I should have a go at changing the feeble horn.

With the tank raised, it took me 10mins to install a Denali Sound Bomb Mini. I purchased the Mini with the Spade to BMW Canbus connector. Works like a dream. I just wanted something easy to install, something louder and deeper sounding that the stock horn and something that wasnt on show. The Denali Mini fitted the bill.

Fitting was simple, just had to use the Nut that came with the Denali to secure it to the BMW bracket.

Great info, I'm in the same camp. I want something thats easy to fit and isn't the embarrassing chirp of the oem horn.

My SoundBomb mini had been sitting on the garage shelf for a good few weeks, so decided to lift the petrol tank and fit it this weekend. The weather was suitably rubbish that working inside the garage seemed to be the best option.

I chose the Mini along with the CanBus connector as I was hoping it would be a straight swap with the original and mount in the same location hidden under the tank.

Unfortunately there is no way the SoundBomb Mini will fit in the same location as the original horn on my Urban GS, I cut the cable ties of all the cables in the vicinity of the horn so they could be moved out of the way, I also bent the mounting bracket as far as it would allow but there is no way the Mini will fit.

In the end I replaced the original horn while I consider if mount the mini in a different location or go for the full size SoundBomb considering i need to mount it in a different location anyway.

On a positive note the petrol tank was easier to remove than I was expecting, I guess I had been preparing for the worst. And it seemed like a good idea to replace the air filter while I had easy access. So not a completely wasted afternoon.

When I removed the original horn from Blitz (2015 Classic) Hack, I used the space to hold a simple automobile stock 12vdc horn relay to which I attached the original hot wire from the horn button so when I hit the horn button the relay clicks and closes contacts as long as I’m holding down the button. Then I ran a heavy gage insulated copper wire with an inline 20amp fuse (under the seat so its easy to change if needed) directly from the battery to the new auto relay, from there I split it into two wires of the same heavy gage one to each side of the oil cooler and mounted my dual horns. They are sooo loud... I love it. Saved my butt in traffic more times than I can count. In traffic I use my horns and flash my high beams dozens of times every time I ride (Very short beeps and flashes) every time I see a vehicle that I even remotely think has not seen me. I know it works, I’ve seen them Stop abruptly when they were going to turn casually right in front of me. People aren’t looking for bikes ....
Loud pipes, loud horns, flashing lights ..... Hell.. Wave your arms if that helps .. BE Seen !
Don’t get dead or injured thinking they’ll drive like you would and be paying attention ..
You Get Attention ! .....StayUpOn2 Take an active and aggressive part in your safety, there are way to many pre-occupied stupid four-wheeled nimrod drivers ...... BeWell .....Blitz
P.S. I also have a shelf where parts are sitting, ..I’m thinking about moving that relay to a new place to make room for a Gorilla Thieft Alarm with remote a pager .... this bike has NO space to add anything ... She’s beautiful ..... but ✌😎 Enjoyed your posts Hack ... stay at it Mate. View attachment 137832

Thanks for the detailed info Blitz, great idea to use that space for a relay, the dual horns on your oil cooler look awesome I'll need to decide if I attempt to replace the original again or go full out with something like you have done.

This is what I fitted. Straight swap, tank bolts loosened but not removed and some skinned knuckles but done in about 15 minutes and massively louder. The plug is the same so no splicing or changing of connectors.

Great tip thanks, if i decide to replace the OEM I'll definitely be going this route.
