I built a stand for my dirtbike ('05 CRF230F) a few months ago out of some 2x4's and some casters rated to 50# each. But the bike is over 200# and it didn't roll very well. So my buddy was moving this weekend and he was throwing out an office chair. I figure the wieght limit on one of them is around 400# considering fat people. So I took the base, screwed an 11"x11" piece of wood to it, and tacked a piece of carpet over it. Thing works amazing. rolls around easily, spins without any issue and best of all has the arm to lower it when I'm done for easy removal!!
