Hi there, I have a 2001 DRZ400S. I know the front forks are not as good as the 02 and older DRZ's. So I am in the process of getting either E forks or '02 and newer S forks. Now for the rear spring and shock, what is the difference between my 01 S and the 02 and newer S and E? Is the difference in just the springs or are the shocks different also? I weight about 185lb and will be about 175lb by spring time. Goto get trim for the ride. Thanks to all the reply.
