I also have a 2009 Ultra, and found from day one that the shocks bottom out with the slightest provocation. I run 30 lbs (the manual says you can go to 50 now), but RR tracks, driveways, speed bumps, etc, etc. make the bike bottom out badly. I weigh 240 and gilrfriend weighs, well, I am not going there. Suffice it to say she is a large girl. Riding solo causes the problem to easily appear, and two-up requires 50 lbs to keep us from both losing our teeth. I have a friend who told me the Progressive shocks are supposed to help, but I cannot get Progressive to give me a weight limit for their shocks. I find it hard to believe that HD would let the bike go out with that kind of bottoming that I experience. Anyone else have any experience with Progressives? I am ready to buy them if it fixes the problem.
