The Kawasaki KX250F is a four-stroke motocross motorcycle produced by Kawasaki between 1995 and 2019. Max torque was 29.5 ft/lbs (40.0 Nm) @ 11500 RPM.
Engine[edit | edit source]
The engine was a liquid cooled single cylinder, four-stroke. A 77.0mm bore x 53.6mm stroke result in a displacement of just 249.0 cubic centimeters.
Drive[edit | edit source]
The bike has a 5-speed transmission. Power was moderated via the Wet Multi-disc.
Chassis[edit | edit source]
It came with a 70/100-19 front tire and a 90/100-16 rear tire. Stopping was achieved via single disc in the front and a single disc in the rear. The front suspension was a 36mm inverted telescopic cartridge fork with 18-way compression damping while the rear was equipped with a uni-trak single shock system with 4-way compression and 18-way rebound damping plus adjustable spring preload. The KX100 was fitted with a 1.32 Gallon (5.00 Liters) fuel tank. The bike weighed just 149.91 pounds (68.0 Kg). The wheelbase was 51.61 inches (1311 mm) long.
2005 Kawasaki KX250F[edit | edit source]

Disc brakes are used for the 2004 Kawasaki KX250F to make sure there is enough stopping force for the most demanding riding styles.
Since the 2004 Kawasaki KX250F is not a street-legal bike, you're supposed to ride it on the tracks or non-public roads/ wilderness trails.
2006 Kawasaki KX250F[edit | edit source]
The 2005 KX250F receives some modern tuning from the Kawasaki engineers, so the new bike comes with a power boost, higher-revving engine and other enhancements. The good old 249cc 4-stroker just got better and can deliver a new level of performance.
A 16-way adjustable forks provide excellent damping on any surface, no matter how hard you hit it, while the new, adjustable Uni-Trak rear suspension complements it in a spectacularly efficient manner.

2007 Kawasaki KX250F[edit | edit source]
The good old 2006 Kawasaki KX250F 249cc 4-stroker just got better and can deliver a new level of performance, thanks to its revised carburetor, engine and gearbox. The updated piston, intake valves and polished intake ports make sure the fuel and air mix flow faster and steadily, never letting you down.
With a new radiator in place, this motocross machine will keep within the optimal working parameters even in long, hard races. The racing-like aluminum skidplate is taller in front of the engine to prevent mud from accumulating and cause trouble.

2008 Kawasaki KX250F[edit | edit source]
Borrowing even more from the factory racers, the 2007 Kawasaki KX250F 249cc is taking further steps towards the modern motocross bikes. Lighter ribless hubs, back alumite-coated rims, short and lightweight silencers, a revised, hardened crankcase and a high-revving engine, they all add up to prove the superiority of the 2007 Kawasaki KX250F over the previous years models.
The engine is loaded in repositioned mounts and rear caliper guard ensures protection during racing on rough terrain, while the Showa twin-chamber fork delivers a stable damping performance. The piggyback rear shock sports enhanced adjustability to make the KX250F respond as needed to the racing abuse.

2009 Kawasaki KX250F[edit | edit source]
The 2008 version of the Kawasaki KX250F sports and even slimmer frame made of aluminum, with revised reinforcement to provide dependable rigidity. To withstand the rigors of motocross racing, the 2009 bike got Showa dual-chamber forks and a redesigned swingarm, while the previous model's rear shock retained the hardware specs, but received upgraded damping characteristics.
A synthetic skidplate was installed, offering the same sturdiness the aluminum one provided but with a lighter design. Wider, serrated footpegs are now in place, to complement other nifty hardware upgrades, such as the factory-style Renthal handlebar and racing-specced petal rotors. If middleweight 4-stroke machines are your game, then the 2008 Kawasaki KX250F is the right toy.
2010 Kawasaki KX250F[edit | edit source]
The 2009 Kawasaki KX250F is a motocross motorcycle powered by a 249cc liquid-cooled single-cylinder engine. Thanks to its lightweight construction, this bike can also be used on other types of dirt tracks and even trails in the wilderness. Be advised that it is not street-legal.
The new year model comes with a higher-grade radiator, less prone to mud build-up, with a thicker profile which makes reinforcement brackets unnecessary, thus shaving off some weight. The titanium-coated Showa dual-chamber forks and revised rear suspension now offer even better shock damping and eliminate the “kicking” effect.
The synthetic skidplate offers the same sturdiness of the old aluminum one but with less mass. The 2009 KX250F sports the 2008 wide, serrated footpegs, factory-style Renthal handlebar and racing-specced petal rotors. The slim shrouds offer enhanced riding ergonomics.

The 2014 MY Kawasaki KX250F comes with the same 249cc single engine as its predecessors, but the Japanese engineers have introduced some other new technologies to improve the KX250F's performance and carry one the heritage of this off-road performer.
The launch control can be activated while in neutral, the first or second gear to maximize traction with the push of a button. It maximizes the take-off thrust, bettering the odds of a holeshot start.
The transmission has been redesigned, too. It now has four dogs instead of three, and this offers smoother shifts. Also, the shift fork grooves have been improved to enhance feel at the shift lever.
Also, the grips have shorter barrels and are softer to improve rider comfort.

The KX250F comes equipped with a 249cc engine, which is slightly smaller than average for a 4-stroke motor. Its seat measures 37.2 inches off the ground, a height that's only slightly higher than the norm and will accommodate riders of many sizes. The 1.61 gallon fuel tank is 15% smaller than average in this class, meaning the KX250F gives up some range to its competitors.
