I have a 2001 Pro X 600. I like it a lot. My only complaint is the rear is too stiff. I had the shocks re-valved and the blocks are set at the lowest level. It has the adjustable dampening RYDE FX shocks which seem to work best at the lowest position. I'm sick of tearing these shocks apart. Is there anyone that knows the solution. I asked the factory and they couldn't tell me.
