I guess Yamaha must have shot their wad on the 50th anniversary model year, last year, because I'm not seeing too much new and exciting for 2007. It doesn't look like much has changed on the YZ line-up, although the WRs did get the new frame. And where is the YZ 150F? The changes with their quads is not that exciting either. They took the fuel injected Raptor 700 motor and put it in the Grizzly, and added electronic variable rate power steering. Power steering is interesting, but all three Grizzly 660s I've owned steered super easy without it. And that makes two fuel injected Yamaha quads, but no fuel injected bikes yet. Somebody show me what I'm missing. It looks like Yamaha was pretty conservative this year to me.
