I just got a call from my buddy who sets up trade show booths . . . He saw the new 07 Yamaha models today! WR 450 has the ALUMINUM FRAME! YZ 450 has an all WHITE plastic kit that he said is REALLY nice!! And as for EFI . . Not yet. I guess we will have to wait until next year. I am trying to get him to snap some photos with his phone when he goes back tomorrow!
