If you have access to a lathe you can make 09 forks work, I've used 05 250f forks on an older 500 and am confident that I could install new ones if I had the need. I would say your 01 forks are equivelent to about a 97 98 KX 250. the newer components are more rigid. you could defineately enhance your 93 forks with something newer. As for shocks, about all you can expect over yours are a larger shaft and piston, and while they may work better it may be only because they are newer. 93 is pretty old, so yeah I think you could benefit from some upgrades, primarily because the 93 units are probably worn and the right newer stuff may not be.
