LOUDNESS THAT MAKES A DIFFERENCE

Being easily heard at a longer distance gives everyone more reaction time. Your honk hearing distance can be increased 3-fold with the MotoHorn™ — a standard motorcycle horn can not compete with that.

LOUDNESS THAT
MAKES A DIFFERENCE

Increases awareness by other drivers and gives them a clearer warning honk.

Lowers your risk of injury and gives you better odds of getting their attention.
Makes your riding experience less stressful in certain traffic situations.
Install MotoHorn 3.0 and alert with loud train-like honks:

DID YOU KNOW?

Modern vehicles are heavily soundproofed and
can block outside noise by up to 20 decibels.

DID YOU KNOW?

Modern vehicles soundproofing can reduce outside noise by up to 20 dB.

WHY TRAIN-LIKE HONKS?

Greatly improved loudness increases honk distance and everyone has more time to react — especially when riding a motorcycle.

Vehicles merging recklessly into your lane or running red lights — some of the most dangerous moments riders face.

Distracted drivers rolling forward at intersections or accidentally hitting reverse — we’ve all seen it happen.

Parking lots full of unaware drivers and phone-scrolling pedestrians — a single scratch costs more than a horn.

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!
Put it on a 2020 Heritage Softail Classic, picture included.

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.
