19yrs 6'5 and 155 pounds. Yesterday I went and rode my buddies 05 CRF250 4stoke. It had alot of power and I liked it. I did well considering it was my first time on the track. but for some reason I am hell bent on getting a 2 stroke just casue i hear they are easier to fix and so on... Would a 250 2 stoke be to much for the average beginner rider? or should I lean towards a 125. I will be buying a used bike 2004 or newer with about $4000 to play with.
