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]

The bike has a 5-speed transmission. Power was moderated via the Wet Multi-disc.

Chassis[edit]

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.

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.

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.
