Is it just me, or is there something not quite right about the idea of using only one side to set preload? Maybe with a Harley it doesn't matter all that much, but I was always taught that it was desireable to match left and right sides as closely as possible (forks and rear shocks) to provide the smoothest action without excessive binding or "stiction". Then I switch to the H-D brand and find that they do silly stuff like using a damper rod in one side of the forks and a cartridge system in the other, with different characteristics constantly working against each other. Talk about causing "stiction". So now they take that same goofy idea and apply it to the rear of the bike, and only use one side to set ride height? Seems wrong to me. In fact, I originally assumed there was a little hydraulic line that connected the two shocks, just like the air line on the air adjustable shocks. I was totally "shocked" when I perused the first example at the local dealership and found no interconnecting line.
