This is a new post.. I'm 6ft 4 inches and weight 245 pounds. I know the stock spring on the 450 rear shock can't be right for me but am not sure how to figure out which one I need. I'm a medium fast rider and do trails and fast stuff in desert. I'd appreciate any input!! wr450, grey wire cut, vortip,scotts triple clamp,damper and protapers Jimmy Buttton bend,acerbis rallypro handguards, panoram speedo. can't find any radiator guards or bigger tank yet.
