Hello, Owned this 1500 since new, absolutely no problems until now (30,000 miles). Needing to replace rear shocks. Not sure which Progressive shocks I will need. Options are 11.5 12 or 12.5 (Refuse to spend the money Kawasaki is asking) . The bike sits absolutely perfect the way it is now, don't need it any lower or higher. Just not sure what size the stock shocks that are on there now, to make sure I get the same size.
