stock spring ok for me?

[rroost]

i race an '05 crf250r (mx only). i'm 5'10"/160lbs. i was told i should use a stifer spring so i could set proper race sag and still get full travel out of my rear saspension. has anyone heard of this? or have any other ideas? thanks

Your stock spring is fine. If anything you should try a lighter spring to get traditional race and free sag #'s.
