I tried to do a search on this topic but, didn't find the answers I am looking for. I just got a new 07 WR450 I am 6'4" 230-235lbs (with no gear). I have not been offroad with the bike yet but, from previous experience most dirt bikes are not suspended for people my size. What modifications are you guys doing to the WR suspension. Is a spring change front and back along with a fork oil change enough? I'm 40 years old and won't be jumping any triples, the bike will see the track once in a while but, mostly trails and hills. I called one suspension shop and it's looking like $550 for front and rear with revalving. I will spend the money if it's needed. If a spring change will do the trick then I will order the parts and do it myself. I don't want to do the springs and then later do the revalve, might as well do it all at once while everything is brand new. Any input would be appreciated.
