I am curious if anybody is using the newer WR450 for motocross. The reason I ask, I have 2 bikes, a 2003 WR450 and a 2004 YZ450. I have my WR450 plated and set up for the riding I love, which is desert riding and gnarly mountain trail riding. I have the YZ so I can race when I take my 11 year old son to race motocross. I would love to have FI and newer suspension but would have to sell both bike to get it. Great for when I ride alone but how will it do on the track?
