Man, you ride Beemers and don't have Fiamms? :-D
I have dual Fiamms on the old airhead. Love 'em. No place for 'em on the Speed Triple (would probably be easier on a bonnie), so I got a Stebel Magnum. Fits the original mount and no relay required.
If I had room, I'd have one of these:
Stebel Nautilus Compact Air Horn
It will kill small mammals.
