I've been riding motorcycles for over 20 years and I've never felt completely confident on the road until I installed the Motohorn. Its incredible loudness and instant attention brings me peace of mind in CA traffic. The installation was simple and I was able to do it myself in less than 30 minutes. I was a bit skeptical, but after using it for a few weeks, I can say it's the best investment I've made for my motorcycle!

I have their 2.0 version and was able to install it on my driveway. The package came as a ready-to-install kit. Can't really say much against the horn. Everything went as expected and the installation was rather straightforward for the Road Glide. Even though it is quite big, many don't even notice it and think it's from the factory.

Horn looks and sounds great, except they messed up and delivered it to my neighbor. Least to say that guy is not happy with my loud exhaust and asking for my loud horn got some stares. This horn does produce enough loudness to outperform loud pipes.

They have somehow managed to make a large air horn for riders that can be actually used in the real world! I was expecting everything to be so much more complex, but the design is well-made and it was very easy to put it on my bike. After hearing it, i can confirm it is basically a train horn, but for motorcycles!

How loud is MotoHorn™?
MotoHorn™ produces 130–150 decibels of loudness and is far louder than any stock horn.
The exact dB rating depends on environmental factors, the number of trumpets installed, and their placement. Trumpet placement alone can influence the volume by ±5 dB.
For comparison, most stock motorcycle horns are rated at just 80–85 dB — making MotoHorn™ significantly louder than factory horns.
Loudness guarantee — If you find a motorcycle horn that is louder than MotoHorn™, we will give you your money back.

Can I mount it on my motorcycle?
Absolutely! MotoHorn™ is designed to fit all touring and larger motorcycles — we’ve seen it installed even on smaller rides.
Complete installation hardware will be provided, you simply have to follow the manual included.
Here are the most popular mounting spots:
- To the HD cowbell bolt.
- Under the saddlebags.
- To the front frame bar.
- To the gearbox cover bolts.
- To the coil pack bolt.
- Attached to the crash bars.

PRO TIP: Use the metal mounting plate for the trumpet installation, this way you can easily mount it to any available spot.

Does it void my ride's warranty?
No — installing MotoHorn™ won’t void your motorcycle’s warranty, and it’s completely safe to install on any vehicle.
Here’s why:
Under U.S. law (Magnuson-Moss Warranty Act), a dealership can’t deny warranty coverage just because you’ve added an aftermarket part — unless they can prove that part directly caused an issue.
MotoHorn™ won’t cause problems:
Our wiring kit connects to your existing horn wires without cutting or modifying anything. It includes a built-in fuse for extra protection, keeping your OEM system untouched and safe.
The worst that can happen? A blown fuse in the MotoHorn circuit — not your vehicle’s wiring. Your factory circuit stays fully intact.
P.S. With 200,000+ MotoHorn™ kits sold, we’ve never had a single case of a warranty being affected.

What is the size of it?
MotoHorn™ dimensions are as follows:
- Trumpet length: 17.5”
- Trumpet highest point from the mounting plate: 4.25”
- Compressor dimensions: 4.3” x 2.9”
- Mounting plate dimensions: 13” x 1.6”
- Mounting plate bolt holes diameter: 5/16″ (~0.31”) — adjustable length
- Air line length: ~16” — can be extended without reducing performance
Total Weight: 2.9 lbs.
Worried about fitment? No need to be! Send us an email with your motorcycle model and we can likely provide you some pictures of mounting examples.

Version 3.0 also includes all of the wiring related parts. You don’t have to cut any of the original wires and our wiring kit is completely safe to use on all rides.
PRO TIP: Install MotoHorn™ under the stock horn button and also keep your old horn for the best multi-tone effects.
