I was speaking with a friend this last weekend that used to own a 450r, and he has a pair of wheels w/paddle tires that have barely been used (basically new). He wants to sell them to me for $25 or less each. I was wondering if these will fit on the XX. I don't really have the time for a few weeks to go down to check them out, but I don't want him to sell them to someone else if they will work. For the price, I'll be happy storing them in my garage just in case.
