I really wish I had not bought my progressive 440 hd's. You have to adjust them for every load difference. They can't be made stiff enough for two up and then you have to soften them all the way for one up. I guess if I only weighed 170lb. and never carried a passenger they would be okay, but with a passenger the bike wallows in tight curves. I'm 205 and my wife is 135 so we are pretty average. I feel that if you are 200lbs and up or carry a passenger stick with the stock shocks.
