I Ride: '09 ZX6R
The '09 shock had 12K on it when I bought the bike. The owner before me was a hefty guy, with a gf to match. I'm sure the pair was over 400 lbs, and they had the suspension near the maximum settings as a result when I got it. So stiff my teeth clattered together, my vision was blurry at any speed. By the time I got another 10K on the bike, I had backed everything off enough to call it good enough, through the next 20K before both ends started to wallow and become more and more vague.
I hadn't ever noticed any significant changes, as a result of damper adjustments. When I rebuilt the fork at ~53K, it showed me that there was no damping control (remaining) on the rear shock. Lloyd suggested a newer used OEM shock could be an improvement, and that was definitely better than what was going on with the '09, by that point. The adjustments actually had an impact on shock behavior.
It's now at the max compression and rebound, and I can tell it's starting to lose ground.
If I can rebuild that '09, I would hope to get a couple of years of decent street performance out of it. 20-30K would be highly desirable. That would put the entire bike at near 90K, and is likely to be at the point where I would have replaced it with something else.
