Honestly... girl to girl... it all depends what your lookin for. I prefer a 2 stroke because of the zip and torque they offer and how great they perform on the race track, but if your lookin for a good trail bike for a good long ride your gonna want a 4 stroke. They´re better on gas and as long as you keep it in good running shape its less likely to break down and need work. 2 strokes need alot more upkeep and maintenance to keep them on top, for instance its normal to replace rings on a 2 stroke every 30 hours on average(if racing).... but ultimately chic.. the choice is yours.. hope its been helpful
