DENALI Split SoundBOMB 120dB Horn


The DENALI Split SoundBomb comes in a “two-piece” design and produces an earsplitting 120 decibels of sound. That’s about 4 x louder than a standard motorcycle horn!

Product Description

DENALI’s Split SoundBomb is one thing, and one thing only, it is massively loud! The 120dB of sound it produces is about 4 times louder than any standard motorcycle horn.

Even the latest Adventure bikes despite being huge bikes have little to nowhere to mount things like auxiliary horns. If you bike is restricted for access space then the split SoundBomb is your friend. With a two piece construction you can mount the separate compressor and the horn chamber independently of each other and use the supplied tube to connect the two halves. No additional wiring just the convenience of trying to fit two smaller pieces into a space where one bigger piece wouldn’t fit.

You can position the two parts of this split horn at different locations on your bike. This split horn would even fit behind your motorcycle’s body panels! There’s no loss of sound output, it is just an incredibly loud motorcycle aftermarket horn.

Our bike has got the split SoundBomb installed (same specs as this Compact SoudBomb). The effect it has when having to use it on the road is amazing. Firstly, you don’t have the feeling your bike has a strangled chicken installed instead of a proper horn. And secondly, you really can see the reaction of the person you aimed your horn at. The SoundBomb Compact is truly the flagship model of DENALI’s motorcycle horn range. It is definitely the loudest bike horn we know!

Apart from the noise there’s the product design to mention. Once installed you can hardly see it any longer. Somehow a bit of a shame as it is actually quite cool looking.

The DENALI Split SoundBomb is of course designed to withstand life in any and all rugged environments. There’s a moulded clamp which mechanically holds compressor and acoustic unit together. The SoundBomb is virtually indestructible, even in high-vibration surroundings.

DENALI Electronics offers three loud aftermarket horns

There are also other versions of the SoundBomb air horn available. Firstly, the SoundBomb Compact, which offers exactly the same specs as this Split SoundBomb, but as a one piece horn. Easy to install, if you have the space on your bike, that is. Secondly, there is the SoundBomb Mini which offers a 113dB low-tone sound. The Mini horn comes in a neat small form factor which can be installed in place of your OEM horn with no other wiring additions or modifications.


Order Info for all Bikes* and Details for BMW** and KTM*** motorcylists!!

*Details for all Split SoundBomb customers:

When installing a SoundBomb Compact or Split SoundBomb on either a non-CAN bus equipped bike or on a CAN bus equipped bike, but without a CAN bus accessory controller, you will need to use the universal DENDNL.ELC.10000 Plug-N-Play wiring kit. You will also need to use the 5 Pin relay that is included in the box that the SoundBomb was delivered in, This relay is NOT included in the harness kit.

Don’t forget to order a mounting bracket for your horn. If you are unsure which is the right bracket for your bike, please get in touch.

** Are you riding a BMW?

If you ride a BMW motorcycle, add DENALI’s BMW OEM harness wiring adapter (DNL.WHS.10100) for Plug & Play installations.

*** Are you riding a KTM?

If you have a KTM 1090, KTM 1190, or a KTM 1290 Series of bike you will need to retain the original equipment horn so as not to upset the CAN bus system. The DENALI universal Plug-N-Play wiring kit DENDNL.ELC.10000 is connected in parallel with the original horn wires

1 review for DENALI Split SoundBOMB 120dB Horn

  1. Tamas S. with his BMW R1200RS

    Based on discussions with Phil and others I went for the full monty for my BMW RS1200: got the D4 lights, the Denali Split Soundbomb horn and the Innovv K2 camera system installed with the necessary CANSmart controller. As I’m useless with electricity, Phil came all the way from Cambridgeshire to my garage and performed a professional and quick installation of all the goodies, plus also kindly connected the heated seat! The product looks great, visibility on the road is super enhanced and if you pass me, you will be on camera ?! Thanks Moto-Mate for the great job and the friendly chat! Highly recommended for your motorbike electric needs, especially if you have a Beemer as he also rides an RS ?
