The Rivco Harley Air Horn grabs drivers' attention with a loud 128 decibel sound! The Harley Air Horn fits Harley-Davidson motorcycles with a left side horn mount. The Chrome Harley Air Horn is easy to install and uses the stock horn button. The Harley Air Horns comes with a two year manufacturer's unlimited warranty. All kits include two horns, air compressor, relay, simple wiring and complete installation instructions. The horns replace the stock horn and the compressor is either mounted under the seat, behind right side cover or on down tube of frame. (Different models vary)

The air compressor creates instant air pressure to the horns. Since the pressure is created so fast there is no need for a storage tank as on Semi Trucks and RVs. Although the pressure is very low (12-15 psi), it delivers a large volume of air (3 CFM or cubic feet per minute). This low-pressure high volume air supply causes the diaphragm inside the horn to vibrate at a high rate of speed or *frequency*. The exact speed at which it vibrates is varied by the length of the horn or trumpet. Together the horn set produces an extremely loud 128 decibel warning blast. This is approximately 4 times louder than most electric motorcycle horns, which usually rate at 87 decibels.

A stock motorcycle horn draws only a small amount of power - less than 1 amp - which comes directly from the horn button on the handlebars producing the familiar weak motorcycle beep. The air horn's electric air compressor draws considerably more power - approximately 8 amps. This requires the use of a relay, heavier gauge wire and a fuse to prevent damage to the horn button contacts, as well as provide enough amperage to run the compressor at full speed. These components are included in the kit.
