for those who wonder what could be my best choice when buyng a 4 stroke dirt bike i tell you that the dr is the easiest bike to control, control gives you confidence. i ride on very narrow trails where top speed is not so important, my friends are riding xr 600 ,xr 400 they cant even see my dust , that is because their bikes are harder to control than mine. on wide open dirt roads the xr 600 just dissapears but not the xr 400 wich i can easely reach when technical trails arrive.test them youll see......
