The YZ250F powerplant is one of the most powerful, rider-friendly engines in the 250 class. It has a remarkably broad powerband and a crisp throttle response throughout the entire rpm range. In fact, its powerband is so broad that it appeals to and works for riders of all different skill levels. The engine’s rider friendliness results from its impressive amount of bottom-end and torque, which allows it to be lugged and short-shifted comfortably but still effectively. Low-end torque is not a characteristic commonly associated with 250 four-stroke engines, but such is not the case with the YZ250F. The torquey bottom-end power pulls well into the midrange and transitions smoothly into the top-end and over-rev, both of which offer an impressive amount of power.
