At the risk of getting being beaten since I'm in a KDX room only I am wondering the differences between a KDX and a WR. I am 17 years old 6'4 and 190 lbs. Never owned a bike before. I want a bike for trail riding only. Lookin to spend around 3000. Want something easy to maintain....thats one reason i'm thinkin of the WR since its a four stroke. Any advice appreciated. THNX
