ive gotten a lot of mixed answers on what cc to start out on im 6 foot 1 and 200 pounds i was looking at an 09 250cc ninja but think size wise it will be to small (from what ive heard) others have said 600cc would be good to start im just a little nervous about the torque involved with that kind of power dont want to kill myself before i learn to ride correctly because i realize riding a dirt bike is way different from a street bike HELP!?
