I have the opportunity to swap forks with an 07 yz250f onto my 05 yz250. My forks are sprung for my weight and ability and the 250f are not. I'm vaguely familiar with the 2 fork designs and I'm a pretty smart guy. That being said, I was wondering if just the cartridges were interchangeable between the 2 forks. So all I would be taking is the 07 cartridges? Or would my 05 springs fit into the 07? Thanks for any help you guys can provide!
