It's legit, and yes, wheelies are about 20% easier at any speed.
As far as I know, this is the only '04 or '05 in the world with a Givi. Nobody makes a kit, so I fabbed one. Handling's not bad, but when it's loaded with 50# of crap, transitions are a bit slower than usual.
This is the rig I took to MotoGP from San Diego to Monterey and back. The whole rig - case/mount/etc pops off in about 60 seconds and the regular seat pops in.
My buddies call it the AWACS, but they're always asking if I can carry something for them. I originally mounted the topcase from the FJR on there, but it sorta looks more like a Winnebago with the larger color matched case and rack.
