I own a ttr225 wheel that I use on my xt. It requires some mods discussed here: http://advrider.com/forums/showthread.php?t=178968&page=478 Post #7168 The big brake is Easy, fast swap. FWIW, I got my wheel for under $120 WITH a tire and tube, make sure you get the brake assembly, however. I love having two wheels. The hard part is the drilling of the sprocket, but it isn't too bad for someone w/ a drill press.
