Kawasaki was rushing to get a 450 to market and that is why James had to run the KX250 outdoors. In one of those rounds he set the fastest lap time too.......in 2005!!
It is amazing that it really wasn't that long ago when two strokes were king. The heavy hitters didn't make the switch in Supercross until 2006 - carmichael, reed, and bubba. Not exactly ancient history.
