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]].

==History==

[[Yamaha]] created the very first single-shock, production [[motocross]] bike ever. This was the beginning of the Yamaha Monocross machines that changed motocross forever. The YZs of this time were near replicas of "Works Bikes" with their aluminum fuel tanks and light weight, lacking only magnesium engine cases and a few titanium pieces. 


==Engine==
The engine was a [[liquid cooled]] single cylinder, two-stroke.

==Drive==
The bike has a 6-speed transmission. Power was moderated via the multiplate wet clutch.  

==Chassis==
It came with a 90/90-21 front [[tire]] and a 110/100-18 rear tire. Stopping was achieved via single disc. hydraulic. in the front and a single disc. hydraulic. in the rear. The front suspension was a  kyb® spring-type fork with speed sensitive damping; fully adjustable while the rear was equipped with a kyb® single shock; full adjustable. The YZ250FX was fitted with a 2.0 Gallon (7.57 Liters) fuel tank. The bike weighed just 212.08 pounds (96.2 Kg). The wheelbase was 57.72 inches (1466 mm) long.
