What makes this bike so awesome isn't groundbreaking technology (you still have to jet it) or innovative revisions (the only changes for 2010 are the stickers on the shrouds). Rather, the YZ250 is an addictive little package due to its potent motor, predictable handling and wholly universal application. To begin with, the powerplant on this bike produces a crisp, strong serving of low-end lug that escalates into good, clean, on-the-pipe power. The response is excellent, and the delivery as the motor winds up is incredibly controllable. Up top, the bike continues to bark before finally signing off, at which point (or, ideally, a little bit before) you simply grab another gear and let it eat all over again. The Yamaha doesn't require as much clutching on an MX track as you may think, and if you simply carry your speed and keep the revs in the peak portion of the powerband (say that five times fast), you won't miss that 450cc four-stroke of yours one bit.As far as handling, the Yamaha has a race-proven chassis that stands up to just about whatever you can throw at it. From big braking bumps to hard hits and G-outs, the YZ250 retains a light, nimble feeling without being flimsy or unstable. Sure, the stock suspension may be slightly soft for heavier or faster riders, but overall the motorcycle is incredible controllable and surprisingly easy to ride. In the corners, the Yamaha shines with excellent tracking and a settled, consistent feel, not at all what you would expect from a non-thumper. In fact, the lack of vibration on the YZ250 really gives the rider a lot of confidence, especially at higher speeds.
