I recently purchased kdx 220 2002. loved the motor hatted the front end(flexed,soft,fork hung down below axial).
So doing some reading here and there i found out a kx 500 triple tree would bolt up with no mods. Be as it may an fellow club member had a entire front end forks,tree,wheel, brakes,all other controls fit.Bolted it up went for a ride,raised the forks all the way up trying to get the geometery balance,the forks are 3.25 in longer,we definitly had somthing here! couldan't quight get the balance i needed but strait line was great pushed alot in the turns.Then called (WER) Drew Smith after our discusions(more than one call)we lowered the forks 2in. revalved,and he had new springs made shorter using the stock spring rate kx500 also at the same time the rear shock was revalved. Well after 100 ml. or so this realy worked well a great eastern woods wepon.
Some other notes: only lost 1 in of travel over the stock forks 9.5 now was 10.25 2002 kx500 forks 46mm are bump stop forks a the bottom of the fork theres a 1.5 in rubber stop. Being an A enduro east coast rider have only bottomed it once hitting a log hit no problems.Great in tight woods,woops. Great set up thanks to WER & Staff.
