So my buddy has an 03 YZ with some really stiff springs and way too hard for his little 165lb girly frame. Just too much for him.

I have stock springs in my 05WR and they are way to spongy for my 250lb all man frame.

Can we swap the springs from bike to bike? :worthy:

Additional info: The 03 YZ springs are from Race Tech and set up for the original owner, he weighed about 200lb's. I know that less than me, but can the springs still be swapped from YZ to WR and vise-versa?

If his 03 is a yz450f, it has a stock .46 spring rate. If your 05 is WR450, it also has a .46 spring rate. Also, he has a 46mm fork and you have a 48mm.

The '03 YZ450 has the 46mm fork, and uses 41.2x462mm springs.

The '05 WR has 48mm forks, and uses 43.5x461mm springs.

They don't interchange.
