This Year’s Buying Guide
Whether you are looking for the loudest motorcycle horn available for sale, or just for a more effective solution for everyday use, below you’ll find a concise guide to help you find your way through what the relevant information is on this topic.
Manufacturers test their devices under certain controlled conditions, but you should keep in mind that the open space and the environment you are going to use the horns in have a significant impact on the perceived sound volume.
Moreover, the sound’s variance is also a subject of discussion as it is heavily influenced by the direction that the horn faces. If it’s pointed downwards, behind a grill, or under some body work, then you can be sure that the output will not be the same as in other types of installations.
Generally speaking, the sound that a set of horns generates depends on the size of each individual trumpet and on the number in the set. Shorter and thinner trumpets will produce a higher pitched sound, while longer and wider ones will produce a deeper tone.
When looking for the best motorcycle air horn, 3 features are important to keep in mind: the working pressure used, the tank’s capacity, and the compressor’s duty cycle. The general rule says that the higher the air pressure, the louder a horn can be.
The air capacity determines how long the horn can blast before the tank will need a refill. As a reference, a 1-gallon tank filled to 150 PSI can provide a blast of 4-5 seconds. A larger tank requires a heavier-duty compressor, since the more you use the horns, the more the compressor will be running.
Before choosing a specific model, you should think about where you are going to place it on your motorcycle. The most common locations are somewhere in the engine compartment or underneath the vehicle. You should make sure that the model you’ll go for can fit into the designated space.
Of course, as we’ve already seen, the horns’ location has a significant impact on their performance, so you want to choose one that is both convenient and allows the sound to be heard. As you can probably imagine, the best spot would be in front of the bike, just under the headlight.
Installation (DIY or Professional)
Once you’ve made up your mind on which model you are going to purchase, you should think about how you’ll actually get it up and running. If you have some experience with the 12-volt installations, then getting the job done by yourself will most probably not be an issue.
Usually, the challenging part is deciding where to mount all of the components, as this might require some hole drilling in the vehicle’s frame and other similar skills. If you don’t feel comfortable doing this by yourself, you can always go to a professional.
Since you are going to give your bike a new face, you can also give the frame a little care and use some good motorcycle wax to add a new protective layer for the season.
Frequently asked questions about motorcycle horns
Q: Can you put a car horn on a motorcycle?
As is the case with other dedicated items such as motorcycle covers, it’s mostly a matter of size and of getting things to fit. The answer to this question is that it depends, as car horns usually require more electricity, which means a dedicated power line might be necessary.
You will most probably also need a relay, but getting a professional to take a look at your motorcycle and tell what the options are might be a good idea. A minor weight penalty might also appear, but most of the times this is a good trade-off for the added safety element.
Q: Do motorcycles have horns?
The answer is a definite “Yes!”. All motorcycles should be equipped with functional horns, and most can be easily operated by pushing a button. This is a legal requirement in most parts of the world and, for safety reasons, you should always make sure that your horns work.
However, there’s an ongoing discussion on whether some of the stock horns delivered with motorcycles are not as loud as car horns. If you feel like you need a more attention-grabbing solution for your safety in traffic, installing a new pair of horns in your bike might be a good idea.
Q: Can I run two separate air horns on a motorcycle?
Here as well, the answer depends on a number of factors. Having two separate air horns means that a double current capacity will be needed for them to properly work. If you can find a way to solve this problem, then you can surely install them and enjoy even safer rides.
There is also a question of space here. As previously stated, you should make sure that the space you need for two horns is available, and that their location enables the sound to be heard, instead of blocked. However, getting a professional’s opinion is the most advisable approach.
Q: Are air horns on motorcycles legal?
In some states, the only types of vehicles that are allowed to have any type of air horns are emergency ones. In other states, air horns can be installed as part of an anti-theft alarm, but they are not to be used when the vehicle is in motion, as this might cause noise pollution beyond accepted levels.
In order to make sure that you comply with all the regulations applicable in your area, you should check your state’s DMV or BMV websites. There you will get all the updated information you need, to keep you safe and compliant on the road.
