I am in the market to buy a new dirt bike. I am a novice rider that rides a lot of Mx and Tight Trails. I am currently 6'4" and about 300 lbs. I know that is a lot of weight but it is slowly coming down. I was thinking real hard about getting a 2002 yz 426 or a 2002 crf 450. What would be some good set up tips for my size? Any feedback would be very helpful.
