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

Product Information

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 hardest part of dealing with the Nautilus or Soundbomb is mounting it on the motorcycle. These are big horns and most motorcycles have very limited spaces underneath the fairing or around the engine for mounting such a monster. The first replacement part on any bike I own is the horn. And I always install an air horn. I have owned this Denali horn, installed on an Aprilia 850 V-twin, for about a year now. Fitment Note: Add our BMW wiring adapter DNL.WHS.10100 below for a plug & play installation to BMW motorcycles. But, using the Extech dB meter, we measured 118 dB at three feet for the Soundbomb, a good showing.

The SoundBomb Original is a powerhouse of a horn, producing an ear splitting 120 decibels of sound. If you want to be heard on the road or trail, this is the horn for you. Because the SoundBomb draws 20 amps of current, we suggest wiring directly to your battery using our plug-n-play wiring harness! Producing a massive 113 decibels of sound, the SoundBomb can be over twice as loud as a standard motorcycle horn! Original equipment motorcycle horns are notoriously awful, with a wimpy “meeep-meeep” type being way too common. 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. The Soundbomb (probably not the best name for a product here in our crazy 21st Century) looks nearly identical to the Nautilus Compact.

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. Securely attach the SoundBomb Mini to the chosen location on your motorcycle. Ensure that it is positioned in a way that maximizes sound projection while avoiding any interference with other components and potential direct spray from road spray. Lexus GX470 featuring DENALI D7 LED Driving Lights, SoundBomb horn, and DialDim Universal Controller 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. We wanted to locate the horn far enough away from the exhaust but as close as possible to the engine. This wouldn’t work on the right side of the F 800 S, due to the exhaust location.

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. Designed to be a direct Plug & Play upgrade from your factory horn, requiring no additional relay or wiring harness. The horn won’t fit behind the exhaust and you don’t want to get these plastic horns near the exhaust anyway (as we learned to our chagrin). The clamp is said to be more resistant to vibrations, which helps to improve overall reliability of the horn.The Soundbomb horn has a hefty 20 Amp draw. It measures about 138 mm wide, 116 mm tall and it’s about 88 mm deep. It also comes with a relay, but as always, we used a pre-made horn relay wiring harness (review). Sound Output However, Twisted Throttle (the Soundbomb distributor/retailer) sells accessory mounting kits for some motorcycles.

There’s nothing like going through all the trouble of mounting a big Nautilus — no easy task — and having it fail before you get the bike out of the garage. Oh well… 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.”

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. 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. But, we had to come up with our own custom mount for a BMW F 800 S, just to show it can be done with some ingenuity. Twisted Throttle said the horn was designed to be more reliable than the Stebel version, while still providing a loud air horn sound.

Motorcycle manufacturers should definitely be doing better, or they should at least sell an accessory horn that has some guts. 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. Some motorcycles horn circuits are not capable of powering this 5 amp horn. If your horn circuits' max amperage is less than 5 amps, or if you are unsure, simply add our plug-n-play harness to bypass the horn circuit and draw power directly from your battery. Also, add our standard relay as this is not included with the horn harnesses.
