I am a very lucky man right now. I got an early Xmas bonus and am going to buy a dirt bike. The KTM 530 EXC or the Yamaha WR450??? I am 6' 200lbs. Live in Colorado and will be doing scrabbles and get to join the 500 club next spring (30% single track, 30% open, 30% mixed mountain/dry lake, 10% street). Any suggestions?????
