What does everyone think about this bike, i was looking at a 4 stroke, but after looking and seeing i can get a used one of these for about 3000 or less these look like a better deal, they are faster and everything, and if i ever get into racing or jumping this bike could handle it, wut does everyone think of it, is it worth getting? im 15 140 lbs and about 5'6" to 5'8" havent measured my self in awhile, i just want to know the pros and cons about his bike!
