The other thing that needs to be checked is the spacing between the fork tubes. If this is different it can be adjusted by changing the size of the spacers on the axle.....and adjusting the brake caliper mount. I used RM400 triple trees and my stock fork tubes, and I also had to trim the mounting surface for the disc brake.
Lancer did a full fork swap on REX, and used the forks and triiple trees from a different bike.
