Buyer’s Guide

Types of Air Horns For Motorcycles

Air Horns For Motorcycles


If you choose the right model, you can get really loud air horns. They are usually one-piece units that are quite easy to install.

You are required to take into account the compressor’s duty cycle, the tank’s capacity, and the working pressure when using these. Look only at ones with the highest air pressure if you want the loudest.

This is determined by the capacity. One gallon of water equals four to five seconds when it is pumped at 150 PSI. You’ll need a larger tank and a more powerful compressor if you want to use it for a longer period.

  • Are they legal everywhere?

Each state has different laws concerning motorcycle horns. You should, therefore, contact the local authorities in the area in which you live to determine whether the particular type of cannabis is legal.

Air horns are only allowed on emergency vehicles in most states. Many states only let them function when integrated with anti-theft alarms. In that case, you should not honk your horn while driving due to the noise pollution that results.


A greater level of visibility on the road is ideal with these. This type is louder than other types and sounds like a freight train horn.

Some high-quality models can be installed on bikes, motorcycles, cars, trucks, trikes, and other similar vehicles.

Knowing that laws differ between states is important when it comes to laws. If you use it around a neighborhood, you might be cited for their loudness. If you plan to purchase this type of device, be sure to check your state’s laws first.


These relatively new products are as their name suggests. However, not everyone will enjoy them.

You can customize the sound of the novelty horn to suite your taste. A horn sound is usually featured, but you can choose to have something else.

Most commonly, it can be easily installed on a wide variety of bikes and vehicles. You should check to see if it is legal in your state before you choose one.


Tests are frequently conducted by manufacturers under controlled conditions, which are often enclosed. As a result, the device may sound dramatically different outdoors or on the open road.

The sound’s variance should also be considered. A loud device facing the wrong direction might not be as loud as one facing the right direction. You will definitely hear a lower amount of noise when you point it down or under body work. When pointing upwards, it will certainly sound louder.

If you have one horn or two in the set, you’ll get different sounds depending on the trumpet’s size. Shorter and thinner trumpets usually have a higher pitch, and longer and wider trumpets usually have a deeper tone.


Technical performance isn’t affected much by weight. A sturdy, windproof construction will prevent the wind from blowing it away. If it’s heavy, make sure the motorcycle isn’t too heavy.


Installation is relatively simple for most of the horns we reviewed. Make sure you always read the instruction manual before beginning. This guide will show you how to attach a motorcycle horn, if you don’t know how.

Installation Space

You should check where you can mount any particular model before purchasing it, since its location greatly affects its performance. When the same device is mounted in two different locations, its sound can be very different. It’s the one right under the headlight that’s the best under the bike.

DIY Installation Mini Guide

Once you’ve found a place for you to mount it, you should check if it came with any mounting hardware.

See the instructions you got for specific details about the power source your device needs. AA batteries or motorcycle batteries will be needed if you choose a novelty or train horn. However, there is no need for a power source with the air type.

A metric open-ended wrench is used to disconnect the negative cable from the battery. On the wiring harness for the bike, find the positive horn connection.

Lastly, connect the positive connection to and secure the red wire of the horn. Connect the ground connection of the wiring harness to the ground wire of the horn.

Ensure that all connections are secure by checking them one by one. Be sure that nothing but the mounting hardware touches the horn. I wouldn’t expect it to work well if it’s touching anything else.

Pros of Professional Installation

You might want to leave the 12-volt installation to the pros if you don’t have any experience with the process.

Despite its seemingly simple nature, it can become quite complicated if you are not careful.

Professionals know how and where to install this type of installation, which is the biggest advantage. The process is usually completed in no time since they are a lot faster.

Frequently Asked Questions

Can I use a car horn?

It would seem that size would be an important factor. Your motorcycle might be too heavy and bulky for something like this. You will also need a dedicated power line for car horns since they use more electricity.

Your mechanic can provide you with some professional assistance if you are determined to do this. An experienced bike owner usually knows what to do for your particular bike. An appropriate honk can be recommended based on their experience.

You should keep in mind that this will add a bit more weight to your motorcycle, but it will also increase safety as a result of the loud sounds.

Are novelty horns legal?

The legality of these devices in most states is an issue, as we mentioned. Often, their sounds are confused with other things due to the variety of sounds they can produce.

It is possible for someone to not recognize that the motorcycle horn sounds like a song when you honk at them. As a result, some states have banned them since they can lead to accidents.


You need to have a Best Air Horns For Motorcycles Harley for your motorcycle. When driving, it is useful to be able to alarm someone in certain situations.

Despite not protecting against accidents, it may be able to prevent them. Thus, it must be able to emit a lot of sound and be reliable.

Choose quality models because a dead horn just when you need it most is the last thing you want. Verify that it is legal in your state as well as its sound levels.
