I have an 03 WR450, but no title to it. I would like to register the bike for the street and found a deal on an 06 WR450 frame with all the paper work. I was thinking of buying the frame and swapping out as much as I can with the 03 to it. I realize that I would / might have to buy new body parts, but that's ok. Am I dreaming that I could do possibly do this? Will the engine swap out? What about the swing arm, subframe and suspension? Any help with this would be appreciated.
