The '''[[Yamaha]] YZ250''' was a single cylinder, [[two-stroke]] [[motocross]] [[motorcycle]] produced by [[Yamaha]] between 1974 and 2019. It is one of the last two-stroke 250cc bikes still in production.  Yamaha produces a four-stroke version made to compete with this version in the [[Yamaha YZ400F|YZ400F]]/[[Yamaha YZ426F|YZ426F]]/[[Yamaha YZ450F|YZ450F]].  The similarly named [[Yamaha YZ250F]] is intended to compete with the [[Yamaha YZ125]].

Having received an all-new aluminum frame one year before, the 2005 YZ250 got a little more motocross edge thanks to some more tweaking and a new, hydro-formed swingarm. The 48mm fork has also been revised, while the rear suspension got a top-drawer titanium spring, too.

The trim of the 2005 YZ250 includes multiple works-style parts and technologies to allow riders to benefit from the best bang their money can buy. Save for the engine, which is a 2-stroke, the frame is almost identical to that of the 4-stroke machines.

The 2007 MY Yamaha YZ250 got a little more power from its 249cc reed-inducted single, with multiple revisions providing better performance for a lot of components, such as the cylinder, power valve system and carburetor. Quick-access clutch and washable air filter make maintenance easier, reducing the time you'll spend in the garage.
