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"> | |||

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 YZ400F/YZ426F/YZ450F. The similarly named Yamaha YZ250F is intended to compete with the Yamaha YZ125.
History[edit | edit source]
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[edit | edit source]
The engine was a air cooled, later liquid cooled single cylinder, two-stroke.
Drive[edit | edit source]
The bike has a 5-speed transmission. Power was moderated via the multiplate wet clutch.
Chassis[edit | edit source]
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.

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.

2003 Yamaha YZ250[edit | edit source]
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.
In the engine department, the 2002 Yamaha YZ250 comes with a new cylinder head and combustion chamber, a reshaped exhaust port, and a revised second gear for explosive power deployment. The factory-spec racing clutch lever is adjustable, and the rear master cylinder and discs are also revamped.
2004 Yamaha YZ250[edit | edit source]
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.

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.
