If you like me have done (or intend to do) the R6 rear shock swap for your 1989 FZR600 you probably found the R6 spring too soft, that's because the standard R6 spring is rated at 9.8kg/mm (548lb/in) whereas 1989 FZR600 stock spring is rated at 13kg/mm (703lb/in). I bought a spare spring that never got used and is gathering dust. It is the correct size for the R6 shock but rated for the 1989 FZR600 geometry. I am just looking for what I paid for it $138.00 US or nearest offer.
