alain, i agree $650. is a high price to pay, as you can ship cars for that, just thought it might be an option, but the way you're going to limit your search, probably better off going to get it yourself.
the reason i suggested a larger trailer is that when i had my suzi LC, i trailered it a lot and the first time i did, i had about the same clearence you're talking about, but somehow the back fender got against the gate and scratched the chrome fender tip i had on her. may have been my fault, but i do know those straps will stretch some, especially on a big heavy bike. i ended up opening the fence in the front, adding a piece of 6" wide channel iron to roll the bike forward about another 8". probably u-haul would take offense to you doing something like that! later, bud
