 Rolling Chassis Kits from Mid-USA Motorcycle Parts - 250, 300 & 330 wide & NEW Rigid Bobber

WARNING - There are people on EBAY saying they are shipping these kits, BUT THEY ARE NOT!  These people are using Mid-USA pictures and parts lists, but don't buy from them. They are sending cheap wheels and parts, and parts that don't fit.  We have learned this from talking to their very unhappy customers.
