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"> | |||

HistoryEdit
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.
EngineEdit
The engine was a air cooled, later liquid cooled single cylinder, two-stroke.
DriveEdit
The bike has a 5-speed transmission. Power was moderated via the multiplate wet clutch.
ChassisEdit
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.
First GenerationEdit

2003 Yamaha YZ250Edit

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 YZ250Edit
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 main feature of this generation was the switch to an aluminum frame.
2006 Yamaha YZ250Edit
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.
2007 Yamaha YZ250Edit
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.
The competition-grade MX aluminum frame keeps the bike light and handling precise, while the speed-sensitive fork adds premium damping and compression characteristics to the ride. Add in Excel rims, Sun Star sprockets, Pro Taper bars and more top-drawer parts to get you past the finish line first.

The biggest 2-stroke off-road machine has just gotten better, and this calls for some hard riding, showing your friends who's the boss of the dirt track.
2009 Yamaha YZ250Edit
Only those who have ridden a 2-stroke quarter liter off-road machine know the adrenaline rush the amazing power and torque combined with a light weight brings... the rest are about to find out. If real-life racing sensations are one of the things you're looking for, then throwing a leg over the 2009 MY YZ250 is the natural thing to do.
The bike's seat was revised for better support and freedom of movement, while other components have been updated, with lower weight and enhanced performance. The bike also got a new anodized chain for this MY, but new wave rotors in the front and rear are also on the menu, as well as a new, re-valved fork.
2010 Yamaha YZ250Edit
A 2-sstroke quarter-liter machine like the 2010 MY YZ250 is a true weapon in the hands of a skilled rider. The engine delivers explosive power as the throttle is twisted and the brawn of this lightweight machine can strike fear in the minds of the faint-hearted. The aluminum frame uses inverted Kayaba forks and a works-derived rear suspension, both adjustable and capable to deliver first-class performance to the discerning rider.
Little has been improved over the previous edition, as it looks like Yamaha's current recipe is a successful one.
