I'm new to the 2 wheel market. I'm looking at getting a four stroke bike. I want a bike that isn't too much for me, but I don't want something that I will quickly grow out of as my skills improve. I went to the dealers and looked at the DRZ400, CRF450R, WR/YZF 400/426 and the YZF250F. I also looked at the KDX220, but have pretty much eliminated it already. Since I'm new to this I wanted to get peoples opinions on the handling and maintenence records of some of these. I'm already leaning toward the 400/426 but not sure about the WR or YZF. I would like to gain the skills enough to get on a motocross track as I am a former quad motocrosser. Raced for 5 years. I owned a 98 kX250, but could never get comfortable riding it. It intimidated me so much, it sat in the garage for an entire year. I'm 6'2", 200lbs. in good shape (not the same as riding shape. Any input, good and bad, will be be helpful and appreciated.
