I wonder if it depends on the riding and manufacture time. I changed out my OEM rear at about 50,000 miles. It wasn't bad but I was starting to get a bottom out on some bridge edges that I hit everyday that I didn't remember the "bang" of that happening. I bought one off a wrecked bike with 5500 miles. There was a nice improvement. Now 12,000 miles beyond that switch, (supposedly total of about 18,000 on this rear shock) the bike lacks that super solid line feeling in wavy corners. Of course the front has 62,000+ on it now. This isn't a bad insecure feeling at all, just not an on rails feeling. So among other things this winter, figure I will renew the front and rear shocks. Considering Hyperpro at the moment.
As for the steering damper, I still have the OEM one. This past winter on 20 -35 F degree days, doing a box turn into where I park you could really feel the resistance of the oil when moving the bars lock to lock quickly. However, I had to re fasten a glove the other morning going 45 mph. I set the cruise on our dead end road going out. As I was doing this there is a dip I hit every day. There is never a quiver etc. However, with hands off the bars an oscillation started and quickly built bigger rather than stop.It stops as soon as one hand is back on the bars. It was time for new tires etc and new pivot bearings in the rear. So I played to see just how this could be reproduced. It centers right around 45. I hand slap the bars kinda on top at 45, no hands on bars and the movement begins and builds. If at 40 or 50, there is a quiver that stops in about 6-8 cycles. At other speeds none.
I changed the tires and bearings. No change in the quiver. One of the guys at the shop says his GS has the same thing at the same speed. I have played some with the shock setting but it really hasn't changed it. I guess if we had a 20 degree morning this week that would help. Since it is only at one speed I most likely will consider changing it after the weather cools and begins to warm again.
