It can be done but with some serious fab work and engineering..... Good luck!

It would require custom inserts at the swing arm pivot/rear hard point, custom front and top mounts, and the possible relocation of the lower engine mount on the frame. Considering the price of complete, running Gen 1 YZ450's, and how much lighter they are, it hardly seems worth the work.
