my weight is 14 stone.i have pre load set on 4 notches,comp 10 clicks out from fully in.dont have any more adjusters on shock.bike done 14,000.it feels like the spring is to soft.i have heard people put an r1 shock on but I don't know what year one they use.there probly loads of shocks that will fit it with very little mods needed,but can work out a lot of money to just try them.
