Dual-tone black Nautilus Compact air horn from Stebel.

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 139dB it can be heard for almost 3 city blocks!

The NAUTILUS horn features compact space-saving engineering that no other twin tone air horn in the world can offer. It is very fast and easy to install because it requires only ONE fixing point (and a single electrical connection). NO TUBES are necessary! The excellent sound output is INSTANT thanks to an incorporated perfectly balanced air jet system. Its incredibly reliable motor withstands more than 50.000 continuos action cycles! The air intake hole has a patented protection system which insures a pleasant High and Low Tone and surprising power! The Nautilus has a beautiful "DESIGN IN ITALY" design which makes it perfect for openly visible applications.

This is NOT a knock-off horn! This is a true STEBEL......... DON'T BE FOOLED BY IMITATIONS!

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.

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.

No wires, fuses, or bike-specific mounting brackets are included.

You may want to purchase the pre-made wiring kit & brackets.

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 139 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 disappointed - 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.

Really Loud Stebel Air Horn April 7, 2016
Reviewer: Byngsboys from Guelph, ON Canada  
Horn installed easily into my 2001 Honda ST1100.  I mounted it to the fairing frame near the right side locking pocket. Very simple to put in and to get operating.
