I have misplaced my owners manual.

What are the stock spring rates that come on WR450's front and rear from the factory?

Standard rear is a 5.2 for the U.S. That is what my bike came with and it has a purple dot near the bottom of the spring for id.

I'm 6ft 4inches and weigh 240. I just took the stock spring which I think is a 5.0 off and installed a 5.6 from Racetech and it made a world of difference. Good luck! :)
