if you bought the bike new, it should have come with a tool kit complete with the nut-like tool that removes the wheel. The tool looks like a hex nut with little deviders on the sides.. hard to explain. I lost the one that came with my old XB9, and I ended up going to the tool shop and picking up a nut/bolt set that was large enough to fit and used that... it was pretty ghetto, but it worked. I have the one for my 1125R still...
