Just ran across this, for those of you who feel the need to put one of those elfin' goiters on the back of your beautiful bike.

I've had a givi case on my 300 for over a year :p

once you've had a topcase you need a topcase on every bike.

There's a much more attractive way to mount a top box that the GIVI mount. I'd suggest a S-W Motech Alu-Rack through Twisted Throttle. Probably a lot cheaper too.

True. And even though they're hideous, they're worth it.
