there are 2 types of two strokes, trail bikes and motocross bikes. the 2 stroke trail bikes are great in trails, considering thats what they are meant for. i would rather have a four stroke though, they are much easier to drive. you dont have to change gears as much with a 4 stroke and you dont have to keep it high in the RPM's. and another advantage to 4 stroke is that you dont have to mix the gas and oil. go with whatever suites you best though. its all about your riding ability and preferance.
