I also have a Champion Solid axle. I put on an Ultimate Seat with the passenger back rest. It sets up straighter. It makes riding better for my wife. We just go back from Alaska, She rode 5700 miles with me. Since the other 2 ladies could only get 17 days off work all 3 ladies flew home from Anchorage. Not bad for my 70 year young wife. Be safe and enjoy the ride. Larry
