Hi all, I just picked up a 2003 yz450f after being off the dirt for about a year after the birth of our first child. I have a question about spring rates and I am hoping someone can point me in the right direction. My understanding is that the stock spring rates for the 03' are as follows: .46kg/mm for the fork 52.0 N/mm for the rear shock Approximately what weight rider are these ideal for? I am about 210-215 with gear and am assuming that these rates are probably for someone closer to 165-175. Thanks in advance!
