ITs actually called the Rack. You can get them on the 05 x-star. And yes if you plan to put your tower down its a hassel but if you leave it up its awsome. Its strong enough to put ropes and vests on it and it has sides so you dont need to worry about them falling down.
I seen a pic of that "Rack" in this months issue of WB mag.. page 70 in the background w/Parks, Hamilton, and Schwenk the thing has what appears to be lil dirt bikes on top.. can it really role like that?? If so that is sweeeeet..
