When I bought my '05 a couple of weeks ago, I was impressed by so many things about the beast except for - the little toy buzzer that jokingly passes for a horn.
Now, I've put the buzzer-type horns on a couple of dirt bikes that I had made street legal and plated, but that was just to get the inspection certificate, not to think that I could actually warn motorists (with their windows up and the stereo playing) to please not pull out in front of me and my 800+ pound behemoth rolling in their direction.
I had given some thought to the Nautilus/Bad Boy horns that many here use. I have the Bad Boy on my FZ1 and it's piercing blare has saved me from day-dreaming lane changers a few times. I've also used the Nautilus on other bikes in the past as well with good results.
But, for the R3 I really wanted something that was just as loud, but had a deeper, more manly tone consistent with the character of the R3 (or maybe a '73 Sedan DeVille). So, I found the chrome version of what I had used mounted on the Thunderbike crashbars of my '01 Tiger 955i - a pair (one low, one high) of Stebel Magnums.
I ordered them from Todd at HornsPlus Automotive: Air horns for sport cars, motorcycles, boats, and emergency vehicles The pair ran me a mere $18.95 (+ $10 shipping). He shipped them quickly and was very responsive to a question I had. I'd certainly order from him again.
New horns mounting for now is on the bottom of the raditor shroud. They're wired through a typical Bosch 12v relay to a fused direct connection to the battery. The stock buzzer remains, so I went ahead and re-wired it back in too.
When I hit the button now, instead of the anemic "meep" from the stock horn, I get a deep, loud and attention-grabbing "BWAAAAAAAH!" Love it.
