I rebuild my front forks and I ordered a pair of progressive springs from 650central for my XS2. They are longer than the stock spring so I can't use the spacer. I measure the "freeplay" with the stock spring and the spacer at the top of the fork and cut a 5/8" spacer from a steel tubing for the new one to have about the same measure. It seems to be ok but I would like to know if anyone use them and how did you install them? Thanks !
