2012 Yamaha YZ250 actionYou see Yamaha YZ250 two-strokes everywhere: On the motocross track, out in the woods, and even being flipped, flung and flopped around on the freestyle circuit. But what is it that makes this bike relevant in a world that has forgotten how to use a ratio rite? The answer, it seems, can be summed up in one word: Performance.

When mixing the ingredients for the YZ250 two-stroke, Yamaha got the recipe right by combining stable handling and great power. The bike is in no way finicky or slow; in fact, it can almost run with a stock 450cc four-stroke with the right pilot on board. But the engine is a snappy combination of steady roll-on, strong mid-range and good top-end pull. The factory jetting is great for most applications at sea level, and we felt that the power was delivered in a crisp and precise manner.

It can be turned with minimal effort and changes direction in the air like a charm, yet there is something about this bike that makes is fairly safe-feeling for riders just coming off on thumpers who maybe have not ridden a two-stroke in a while. Granted, the YZ250 is not exactly a beginner bike, though the engine will chug down low and the overall package does not wear the rider out nearly as fast as some other bikes.

We put Chris Barrett, a sub-200 pound pro motocrosser and off-road junkie, onto the Yamaha for his initial impression. Here is his breakdown of the YZ: “It’s hard to do a lap on the YZ250 without smiling. The sound alone gives you the warm fuzzies, but that’s just the start – as always, this bike flat out rips. The crisp snap of the 250 two-stroke is a breath of fresh… well… pre-mix, but that too is still a welcome break from the world of four-strokes. Yamaha has the YZ250 motor dialed in with a strong bottom to mid pull that still revs really well. This 250 two-stroke has amazing roll-on power, but can quickly breathe some fire with just a snap of your wrist. If you feel that is still not enough, than just give the clutch a quick dab and I’m sure you’ll be satisfied. The suspension works well and does a decent job of keeping the two-stroke dance to a minimum. Just make sure your sag is set and you should be good to go with just a click here or there to match your preference. And of course the biggest benefit of the two-stroke – this bike is light. It feels light, corners light and jumps light. Even with the raw two-stroke power, this bike is so easy to ride. If you are tired of your four-stroke riding you around the track, maybe it’s time to give the YZ250 a throw and bring back some great memories.”

Although unchanged, the bike still has more than enough potential to remain a great option for riders looking for a fun motocross bike, an incredibly capable woods platform, or simply a fun do-it-all machine to play ride on. Whatever your flavor, don’t discount the YZ250 just because it doesn’t like straight gas—there is a lot more to this machine than meets the eye.
