Motorcycle Horn Buying Guide
Whether you’re looking for the loudest motorcycle horn you can find, or you just want drivers around you to be more aware of your presence, this guide will help you out.
Here are the different features and other factors to consider when you’re shopping for a new motorcycle horn upgrade.
Most of these devices are tested under certain controlled conditions. When you’re actually using the horn, in an open space and loud environment, the perceived volume is going to be different.
There’s also the sound variance that needs to be considered. This would be influenced by the direction that the horn is facing.
As we mentioned earlier, if the horn is pointed downwards or installed behind or under some motorcycle components, the output won’t be the same as if it’s in the open.
Generally, the sound that horns can generate depends on the size of the individual trumpets as well as the number of trumpets in the set. Double check the product description for a better idea of sound levels that you can expect.
Some riders will be looking for the best motorcycle air horn to install on their bikes. For this upgrade, there are some particular features to keep in mind.
These features include the air horn tank capacity, the compressor duty cycle, and the working pressure used. The higher the air pressure, the louder the air horn will be.
As for the air capacity, this determines how long the air horn can last before the tank needs to be refilled. To bgive you a better idea, a 1 gallon tank with 150 PSI of pressure could provide a 4-5 second blast of air.
Larger tanks will require a larger, more heavy-duty compressor. The more the horn is used, the more the compressor will be running.
Space for Installation
Before settling on a specific model, you need to think about where you’re going to install it on the motorcycle. Most people install them in the engine compartment or underneath the bike.
It’s important to make sure that there is a room for installation and that there is a mounting point for the horn. Choose a location that’s convenient for installation and where the horn can be heard.
The best spot for installing would be in front of the bike, such as underneath the headlight or radiator. It’s important for it to be facing the outwards direction in the open so that other drivers can hear when you hit the button.
How to Install a Motorcycle Horn on Your Own
Installing your own motorcycle horn is pretty easy. Start by finding a place to mount it and check to see if it came with any mounting hardware.
Next, take a look at the instructions to see the power source it requires. You might need batteries, though most devices can be installed through the existing wires.
Go ahead and disconnect the motorcycle battery negative terminal. Take a look at the wiring harness and find the positive horn connection.
Once you found the right connection, attach and secure the red wire and the positive connection on the horn. Then, attach the horns ground wire, which is typically black or green, to the ground connection of the wiring harness.
At this point you’re all done so check the connections until you’re positive that everything is properly connected and secured. Double check that the horn works and you should be good to go.
- The sound of the horn is directly affected by where it’s pointing. Keep this in mind when you’re installing the horn. Avoid having it pointing down or installing it behind a grill or other motorcycle components. This would affect how the sound travels and how effective the horn is when you’re using it.
- The size of the horns trumpet affects the sound as well. Thinner and shorter trumpets will produce a higher pitched sound. Longer and wider trumpets will produce a lower pitched sound.
- When you’re installing the horn, the best place to put it is underneath the headlight. This is the most accessible location and also where the horn will be the loudest. You may need to drill holes in the motorcycle frame or use other attachment points for installing the horn.
