My 'Busa is my 6th street bike, and as all the others, it had a horn I did not care for.
Instead of a little "peep" sound I wanted a "
BEEP"!
While this will not be as loud as cramming 5 airhorns into your 'Busa chassis (see other threads, it is neat!), it is a nice bolt on that will fit in the stock location and wiring without Front Fender clearance problems, for about $26.
This horn is a similar style as the stock horn (vibrating disc), but alot louder with a much lower tone. If I had to describe the sound change, it is like going from a scooter to an industrial forklift! It draws less current than a full sized car horn (only 4 amps), and is actually louder, at 132 decibels!
In the picture below it shows the Car Quest part number, the second picture shows how you will have to modify the stock bracket, and the third shows it installed.
I liked it enough to share with you folks. If you decide to try one, be sure to hook it up to your battery before installing it to test the sound. Since it is a unique tone, it kind of cracks me up when I honk at people and they look at the 'Busa funny.
