The '''[[Yamaha]] YZ250''' was a single cylinder, [[two-stroke]] [[motocross]] [[motorcycle]] produced by [[Yamaha]] between 1974 to present. 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]].

Improved Monocross suspension, lighter and stronger swing arm, rear shock redesign, larger air box, Z-spokes, redesigned frame and exhaust pipe, lighter and stronger forks. Far more than a warmed over ’83 model, the YZ250L went through a major revamping. Targeted refinements and a huge injection of horsepower made it one of the most competitive bikes of 1984.<gallery mode="packed-hover">

There's no F after the 2002 YZ250 so we're dealing with 2-stroke might, this time. This model year received a lot of improvements, starting with a new, lighter and tougher swingarm and recalibrated suspensions, with more precise travel and providing even more control.

With around 40 years of YZ250 history, it was natural that the 2003 iteration carried on the acclaimed nerve and maneuverability, in a package with received multiple updates for even higher performance and more durability. The forks went up to 48mm and received a new coating for smoother action, and titanium pegs shaved off some more weight.

The 2003 YZ250 receives a new gripper-style seat cover, revised engine internals for a better mid-range power deployment, and an adjustable clutch lever for quick, on-the-fly fine tuning.

With around 40 years of YZ250 history, it was natural that the 2003 iteration carried on the acclaimed nerve and maneuverability, in a package with received multiple updates for even higher performance and more durability. The forks went up to 48mm and received a new coating for smoother action, and titanium pegs shaved off some more weight.
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, hydroformed swingarm. The 48mm fork has also been revised, while the rear suspension got a top-drawer titanium spring, too.


The 2003 YZ250 receives a new gripper-style seat cover, revised engine internals for a better mid-range power deployment, and an adjustable clutch lever for quick, on-the-fly fine tuning.
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.
