ya i am 15 and i got my 83 250r last year and it didnt take me long to get used to riding it, just like every one says lean alot when drifting or making sharp turns and to get really used to how easy it is to flip, try riding on two wheels by leaning to one side and turning a bit to pop up the outer wheel(depends what side u do it on) and try to ride in a straight line and keep it balanced. have fun!
