Denali SoundBomb™ Mini Electromagnetic Low Tone Horn 113dB Motorcycle Horn

Product Information

It is recommended to not over tighten the bolt on the rear of the SoundBomb Mini. The horn should be secure, but should give way if rotated with pressure. Tighten the M6 nut to no more than 6.5 ft.-lbs. If the horn is too tight, it might not sound correctly. Fitment Note: Add our BMW wiring adapter ( DNL.WHS.10100) for plug & play installation to BMW motorcycles. The Denali™ SoundBomb was designed for those who want to be heard, but still want to maintain a stylish look. But a webBikeWorld visitor who read the instructions more carefully than us (!) wrote to let us know we made a mistake. In fact, we wouldn’t be surprised to learn that the Soundbomb is made by Stebel or by ex-Stebel designers.

However, Twisted Throttle (the Soundbomb distributor/retailer) sells accessory mounting kits for some motorcycles.

Step 2: Remove the Stock Horn 

Some motorcycle owners have opted for the huge Stebel Nautilus Max (review) or more likely, the Stebel Nautilus Compact (review) as their replacement horn choice.

The mounting problem is even more complicated because there’s just a single bolt location on the horn body that can be used for mounting. This is a cast metal cutout that fits the 8 mm hex head bolt that comes with the kit. Producing a massive 113 decibels of sound, the SoundBomb can be over twice as loud as a standard motorcycle horn! At 113 decibels, the distinct low-tone sound from the DENALI SoundBomb Mini is over twice as loud as a typical 100 decibel disc horn. So we cut a longer (18 cm) length of aluminum, drilled the two holes as noted below and re-installed the horn, this time in the correct orientation.

Designed to be a direct Plug & Play upgrade from your factory horn, requiring no additional relay or wiring harness *.

If they did, we guarantee that just about every owner would go for the option, adding to manufacturers’ and retailers’ profits. Currently, the manufacturers are leaving money on the table. Twisted Throttle also sells a wiring harness for it and various length/configuration coated steel attachment parts. I acquired all the kit I needed from TT, and the install went smoothly.The horn has a higher pitch “European sports car” sound than the Stebel Nautilus horns or the Fiamm Freeway Blasters (review) or the Stebel Magnum horns (review) now mounted on the 2014 Suzuki V-Strom 1000 ABS (Blog), which sound like a loud car horn. Denali Soundbomb .mp3 The Denali Soundbomb horn was made for Twisted Throttle as a replacement for the Stebel Nautilus Compact. Without getting into too much detail, we were told that TT needed to find a replacement for the Nautilus, for several reasons. From “E.Z.” (August 2015): “I have a working Stebel Nautilus Compact on my NT700VA. It sounds exactly like the Denali on your .mp3 file! Sometimes, though, there’s no enough room under the hood for a one-piece horn, and that’s where the DENALI SoundBomb Split comes into its own. It’s the same basic horn as the SoundBomb Compact only with the 12-volt air compressor and the horn itself separated by a supplied durable hose. This feature allows installers to locate each component where they make the most sense, without compromising performance. Like the SoundBomb one-piece, the SoundBomb Split is available with a plug-and-play wiring harness that includes a water-resistance relay and high-quality wiring with pre-installed connectors.

The instructions note that “the horn should be mounted so that the cylinder is vertical with the horn facing down. There should be no more than a 25 degree variance from the vertical position.” A motorcycle horn is not just a federally mandated accessory or a nice-to-have. And a horn loud enough to get the attention of errant and careless drivers is not just a luxury. For daily riders, touring fans, and city commuters, an attention-getting horn is much, much more—it’s a necessity.But, using the Extech dB meter, we measured 118 dB at three feet for the Soundbomb, a good showing. A high-value alternative, one that’s really handy when space is absolutely at a premium, is the DENALI SoundBomb Mini Low-Tone Horn. Far more powerful than horns on most powersports vehicles, the SoundBomb Mini sill puts out 113 decibels of attention-getting sound but fits into a space less than 3.5 inches square and 2.5 inches deep. Moreover, the Mini is quite power efficient, meaning that many vehicles can handle the needed 5-amp load without needing an external power relay. And if that’s not the case for your application, a Plug&Play harness is also available.
