Dual-tone air horn from Stebel of Italy available in Black or Chrome. Loud enough to convince other drivers that there's a derailed freight train barreling down on them. Don't press the horn button in the garage, it hurts! At 114 dB it can be heard for almost 3 city blocks! YEEEOOOWWW!
Note: Stebel horns currently ship in packaging with FIAMM branding, do not be alarmed, they are the same product.
Includes a single M8 mounting bolt and nut, as well as a relay for providing a direct, high current attachment to the motorcycle's battery.
No wires, fuses, or bike-specific mounting brackets are included.
Need wiring help? Check out this horn relay wiring diagram. If you're still confused, you should probably buy our Plug-N-Play wiring kit for Stebel Compact Nautilus Airhorns.
Previously, I'd tried the stock (go-cart) horns on my Suzuki DL1000 V-Strom, then moved to dual FIAMM Highway Blasters with a dedicated horn relay, which were a significant improvement. Still, I felt like other drivers couldn't hear my horns very well on the highway.
With the Stebel air horn, there's no doubt that people can hear me. When I tried them outside of TwistedThrottle.com's warehouse, everyone in the warehouse (as well as two of our neighbors) came outside to see what was going on. These horns are really freakin' LOUD.
Michael, our former warehouse manager, affectionately calls them "People Deafeners."
Keep this in mind: sound energy doubles for every 3 points you go up in the decibel scale. It means that the Stebel Nautilus horn, which produces 114 dB of sound, puts out a LOT more sound than these popular horns:
- 800% of the sound energy of the more expensive 130dB FIAMM Freeway Blaster;
- 600% louder than the $140, 130 dB Pro Pad Mini Beast horn;
- 650% louder than the $179, 128dB Rivco dual trumpet horn.
You will not be dissapointed - just make sure you wire the included relay properly, as replacement horns used without a relay don't get enough electrical current to be fully effective.
- Sound Output: 114 dB
- Operating Voltage: 12 Volts
- Absorbed Current: less than 18A
- Fundamental Frequency: 530 Hz & 680 Hz
- Weight: 0.6 kg (1.3 lbs)
- Dimensions: Approximately 4.8"x4.5"x3"
- Reaction time: less than 90 milli-seconds
In addition to this horn & relay, you'll need to pick up the following items from Auto Zone/Pep Boys/Radio Shack to complete installation:
MATERIALS (not included with horn):
- 14 to 16 gauge wire, 10 ft - 20 ft length (more than enough)
- 2 splice-in wire connectors (blue plastic variety)
- 6 female blade-style quick disconnects (Radio Shack 64-3049)
- 3 ring connectors for attachment to battery terminals
- 1 in-line fuse holder with 30 amp automotive fuse
- weather resistant electrical tape (or just use weather-sealed heat-shrink connectors)
Stebel Horn Vs. a stock horn on a Yamaha FJR1300
Also fits ATVs, scooters, cars, trucks, freight trains, airplanes, steamships, cotton gins, and any other vehicles equipped with 12-volt power.
Per the manufacturer, this horn should be mounted so that the cylinder is vertical (with the horn facing down). There should be no more than a 15 degree variance from the vertical position. If it is not mounted per these specifications, then the horn may cease to function after a period of time.
If you own a 2003-2005 Harley Davidson motorcycle and horn relays are repeatedly failing, please visit your local dealership to upgrade your horn button under the Harley recall.
Installation on the Suzuki DL1000 V-Strom:
To fabricate the mount shown on the Suzuki V-Strom pictured on this page, you'll need the following:
- one 20mm x 100mm x 2mm strip of aluminum or steel (to fabricate bracket)
- one metric M8 nylon locknut
(1) Drill a 6.5mm diameter hole about 10mm from one end of the metal strip, and drill an 8.5mm hole about 10mm from the other end of the metal strip.
(2) Place two 45-degree bends in the metal strip, each in opposite directions. The first bend should be about 20mm from the end of the metal strip with the 6.5mm dia. hole. The send bend should be 30mm further from the same end of the metal strip.
(3) Bolt the 8.5mm hole end of the metal strip to the horn using the M8 locknut.
(4) Bolt the 6.5mm-hole end to the bike using the stock radiator mount screw on the left side of the bike, facing the offset toward the center of the motorcycle.
Installation on other bikes may vary! If you've documented how to install the horn on your bike, send us the photos & instructions, and we'll post them for everyone!
Note: The horn model offered here is the Compact Stebel Nautilus model, which is produced in all black OR chrome with black trim. The Compact Nautilus is the smallest, loudest, most vibration-resistant model offered by Stebel, and is the most appropriate for use on motorcycles.
The Original Stebel Nautilus is a significantly larger (but not louder) horn model that is produced by Stebel in black, red, or chrome-plated plastic. It is prone to damage from motorcycle vibration, and the chrome-plated plastic version has a poor finish that chips easily. For these reasons, we do not offer the Original Nautilus model.

I can't recommend this air horn enough, best $50 I spent on an aftermarket part for my Burgman ever. Even with my helmet on at 75mph it's painfully loud, and that's a great feature in a horn. (Posted on 9/2/15)

The only problem I have ever had with this product is that I can't find a place to install it on my new Triumph Thruxton. I have installed one of these on a Honda ST1300, a Honda CB1000R, a Honda Shadow Spirit and a Suzuki Bandit. Never been disappointed in the performance. (Posted on 8/19/14)

Mounted inside the cowling of my 2009 DL650A. I used the included relay powered by the stock horn and power leads back to the battery.
If you give a quick hit of the horn button, the horn emits a short "bleep" - hold it down and you get the full volume.
For some reason, motorists do not react aggressively to this horn the way they do to standard diaphragm horns. So you can use it whenever there is a potential threat without irritating everyone around. I've even seen people smile at the sound!
Recommended for all cyclists and I may even put them on my eBike!
