Denali SoundBOMB 120dB Horn

Brilliant for saefty

This horn is very, very loud. I fitted this on to the rack of my 1200GSA behind the left hand pannier. It gets the attention of drivers who would otherwise not have heard or ignored you. I hooked this up to my HEX Ezcan and the installation was very simple other than having to make a bracket to fit it to my pannier rack. I changed bikes to a 1250GS and the only place I found to mount it was inside the fork legs. Denali offer a fitting bracket to do this and which is an easy fit if a little cramped. Great service as usual by SBS

Blows your ears off

Have been wanting to upgrade my bike horn for ages, as all stock horns are SAD :( you just can't be heard by other road users. After doing some research I just had to go for the Denarli sound bomb. It says 120db on the box but in some sound metered tests, it reached 124db!, I thought it would be tricky to install, my local bike dealer quoted me £150.00 to wire it in and fit it!, but thanks to YouTube, there is plenty of good advice, and I fitted it myself in approx 30 minutes. I most definitely recommend buying the wiring harness, sold separately which keeps everything simple, the only tricky bit was routing the wires, but once I had that sorted, it was a really neat job with the help of cable ties. I'd also recommend buying a dedicated bracket for your make and model of bike, which will make the horn kind of blend in with your machine, just do a search online. They also make a single horn version but it doesn't sound as good as the twin does, now when I'm out riding I can definitely be heard...BLAHHHHHHHH

Essential bit of kit

This can stop sleepy drivers in their tracks and certainly gives them a wake up call ! It is also useful at motorway speeds to let drivers know you are right there when they try to pull into your lane without looking. Factory fitted horns are pathetic by comparison, this is actually very effective, Second one I have bought, first one failed after a bit over 1 year of all weather use, probably clogged with salt and road dirt, might be possible to clean but haven't had time yet. One bit of advice, get the extra wiring harness which is sold separately, it is well worth it and makes fitting much easier.

Quality aftermarket horn

This is a good horn which I bought to increase safety (more likely to be heard by drivers at motorway speeds). Service from SBS exemplary as usual.

Producing an ear splitting 120 decibels of sound, the Denali SoundBomb is four times louder than the standard motorcycle horn. The Denali SoundBomb was designed for those who want to be heard, but still want to maintain a stylish look. Thanks to its compact design and black housing, the SoundBomb will practically disappear once installed. The unique design of the SoundBomb horn features a rugged, moulded clamp that mechanically mates the compressor to the acoustic unit, making it virtually indestructible even in high vibration applications.

Questions and Answers

  • Would this be compatible to use on my car using the plug and play harness thanks

    August 28, 2018

    It's just a positive and negative spade terminal so should be a simple case of swapping the wires.

  • Can this horn be fitted as a direct replacement using the two factory connectors or does it require a relay? Regards Geoff

    October 2, 2017

    The Denali SoundBOMB 120dB Horn requires a relay, which is supplied with the product. If you are looking for a horn that can be fitted as a direct replacement for the OEM Horn, try the Denali SoundBOMB Mini 113dB Horn. (Quick Find Code: 341283)
