Part # 44720002
Stebel Nautilus Horn

Had this horn on my 16' bmw 1200 rt for a while now and only other problem i had to fix besides the cheep relay was putting a higher amp fuse in. When you have to lay on the horn for awhile to really get someones attention it blows the fuse. Stronger fuse fixed this problem and i tell you when people hear this horn they jump about 4 feet and look right at you !! I have decided to install this on my two other bikes for safety reasons of course and I get a laugh out of the looks on the drivers face!!! I can see how other buyers might have problems as it is a little tricky but its worth the "frieght train comin" blast!!

I tried three times to install this horn with the recommended wiring kit. No luck, always had to back out and put original horn back. Installed a Denali CANsmart and tried again wiring the Nautilus directly to the horn connector and the horn functioned as advertised. Very loud every time and easily heard at highway speeds through cars. In my searching during installs I saw a lot of threads about failed relays in the wiring kit from the factory. I believe the relays in the wiring kit are sub-par--so save trouble and purchase your own relay at an automotive store or use a Fuzeblock or CANsmart--you'll save a ton of time.

Installed on my 2016 r1200rt. Instructions are not very detailed but helpful none the less. Horn is VERY loud and worked well except relay would sound horn when I hit a bump so had to replace that with a better quality one from napa. Otherwise it works fine.
