Yep, any bike with higher miles (30k+) has a lot less damping in the shock than it had when new. But the deterioration is slow and gradual, so it's hard to notice unless you do a back-to-back comparison with a new bike.

To the OP: the springs don't wear out, but everything else does, or at least needs some maintenance. Fork oil should be changed (I do mine with every new front tire), rear linkage and swingarm bearings should be inspected and lubed, fork bushings inspected and replaced if needed, steering head bearings inspected, lubed and replaced if worn, wheel bearings checked...etc.

While the springs don't wear out, they're too soft for virtually everyone. The stock front rate is good for someone weighing 50lbs, the rear for about 150lbs. The front is easy to fix, but the rear is harder since just putting a stiffer spring on the shock overwhelms the available rebound damping. So you need to either revalve the stock shock or go the aftermarket route.

50,000 and mine was noticeably worse than at 30 or 40K. Always had to use full preload when loaded for trips. New spring and a Sasquatch make it better than new. Forks get a fluid change every 10K. Can tell the difference immediately.

I have found that the hydraulic preloader on most rear shocks will go out of calibration, probably due to the expansion of the rubber hose and bladder that does the preload. If the shock is not visibly leaking, this can be fixed by removing the banjo clamp from the preload adjuster, pushing the piston down, and then topping up the fluid with something like hydraulic jack fluid. Doing so will restore the preloaders full range of adjustment and costs nothing.
