These air horns give a loud warning blast of 128 decibels! Uses the stock horn button. Can be easily installed in 20-30 minutes.
All air horn sets are bolt on and plug-in, requiring about 30 minutes to install. They include the compressor, dust/bug covers, all necessary hardware, hoses, wiring, fuse, relay and detailed instructions with pictures.
The trumpets are triple plated chrome as well as the mounts and brackets so the shine and finish will last for years to come. They are completely waterproof. No drilling is required: bolt-on, plug-in installation. Cone shaped covers are included which mount to the front of the trumpets. One year unlimited warranty.
All kits include horn assembly, air compressor, relay, simple wiring and complete installation instructions. These horns mount to the front right side engine guard, with the compressor mounting to the frame behind the lowers.
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.
