The 2007 Kawasaki KX250 is a dirt/ motocross bike powered by a 249cc single-cylinder, liquid-cooled 2-stroke engine capable to deliver more than 58 hp. While the bike's nature is clearly intended for racing purposes, it therefore lacks a headlight and blinkers, being thus illegal for street use. You can enjoy it on the dirt tracks or mountain trails, or non-public roads, however. Given the aggressive and explosive character of the power unit, the 2007 KX250 comes with petal disc brakes for dependable stopping force, while the design of the very rotors keep them clean, with no dust or mud diminishing their capabilities. The perimeter steel frame is both light and rigid, offering great handling, especially with the 2007 KX250 weighing only 97 kg (214 lbs). Fully-adjustable suspensions make this bike suitable for pretty much any rider and any riding style on a variety of surface types.

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 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.

2010 brings fuel injection for Kawasaki KX250F, transforming it into an even better motocross machine. The electronic injection provides lag-free acceleration, with a more predictable and smoother power deployment, dramatically changing the feel of the bike.
A new Showa fork has been installed, with separate functions for each leg: damping for the left one and spring for the right one, providing far better response on rough surfaces, with smooth yet firm action that's hard to reproduce in conventional forks.
The new throttle body also brings the opportunity for engine mapping tweaking, using the KX FI Calibration Kit. Custom mappings can be easily made while storing and analyzing the riding data can provide great racing  improvements for the expert rider.

The 2011 Kawasaki KX250F takes another step toward a dream motocross bike, now sporting dual injectors, a first in the world class.

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 2015 MY Kawasaki KX250F sports some new features and improvements to make the 250cc class two-wheeler perform even better on the dirt.
New revised damping settings in the Showa Separate Function Fork (SFF) and revised Uni-Trak rear shock settings make the bike more responsive and easier to handle. The new adjustable footpegs and handlebar clamps mean that a wider variety of riders may enjoy it, no matter their inseam or armlength.
Also, the brakes are new, with 270mm front and 240mm back rotors. This means more efficient braking before turns and improved overall control over the two-wheeler.

The Kawasaki KX250 was a 250cc, off-road motorcycle and motocross motorcycle manufactured by Kawasaki from 1974 through 1976 and again from 1978 through 2007.

Kawasaki did not produce production motocross machines for the 1977 model year, as their previous version had been proven obsolete by the introduction of long-travel suspension by Kawasaki's competitors, most notably the Suzuki RM250A. Kawasaki returned in 1978 with a limited production and totally revised KX240A-4. The 1980 KX models were the first to use a modern single-shock rear suspension. Water-cooling and front disk brake were instituted with the 1982 models.


History

The KX250 introduced in 1974 was Kawasaki's first serious attempt at a production motorcross bike. This differed from their earlier efforts in that it wasn't an offshoot of a mainly enduro themed machine. It began a line of production motocrossers that are highly respected for their strength and competitiveness. Kawasaki has always followed a route of continuous development for their KX series lending them to always be competitive and for the speed at which factory racing developments make it into the production machines.

The first KX250 was based largely on Jimmy Weinert's 1973 machine.


Engine

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. Fuel was supplied via a double overhead cams/twin cam (dohc).

Drive

The bike has a 5-speed transmission. Power was moderated via the wet multi-disc, manual.

Chassis

It came with a 80/100-21 front tire and a 100/90-19 rear tire. Stopping was achieved via single disc in the front and a single disc in the rear. The front suspension was a inverted telescopic separate function front fork (sff) type 2, 22-way compression damping, 20-way rebound damping and 40-way spring preload adustability while the rear was equipped with a uni-trak with adjustable dual-range (2 turns high speed / 19-way low-speed) compression damping, adjustable 22-way rebound damping and fully adjustable spring preload. The KX250 was fitted with a 1.66 Gallon (6.30 Liters) fuel tank. The bike weighed just 203.93 pounds (92.5 Kg). The wheelbase was 58.19 inches (1478 mm) long.

2005 Kawasaki KX250

The 2004 Kawasaki KX250 is a middleweight off-road motorcycle for the intermediate and experienced riders. It sport a steel frame designed to provide the ultimate rigidity with minimal weight and the re-engineered swingarm now boasts new sporty linkage angles for better response to the demands of the discerning pilot. With separate air and oil chambers, the front Kayaba suspension is fully adjustable and can offer innumerable setups when combined with the 16-way adjustable compression and rebound rear shock. The 249cc 2-stroke engine is no toy: it produces more than 58 hp, so the addition of petal brake discs is a most welcome upgrade.


2006 Kawasaki KX250

The 2005 Kawasaki KX250 is a dirt/ off-road bike, with no street-legal equipment, such as headlight or blinkers, and is intended for track and non-public roads, as well as for trails in the wild areas. The 2005 KX250 sports a 249cc 2-stroke engine, but this bike is no toy, as it produces in excess of 58 hp and should only be ridden by pilots with at least intermediate experience. The suspensions of the 2005 Kawasaki KX250 provide innumerable setup positions, thanks to the massive 48 mm oleopneumatic Kayaba forks and new Uni-Trak rear shock. The bike weighs in at only 97 kg (214 lbs) and that's one of the reasons for eliminating the electric starter. The lightweight construction is also helped by the steel frame.


2007 Kawasaki KX250

Designed to be ridden by intermediate and experienced pilots, the 2006 Kawasaki KX250 is a nice middleweight off-road bike packing a lot of nifty features. First of all, the bike is not street-legal: it has no headlight and blinkers so it is to be ridden on the dirt and motocross tracks, non-public roads o wilderness trails. The 58 hp (43.3 Kw) 2-stroke liquid-cooled engine is no toy and for dependable stopping force, racing-class petal disc brakes have been installed. Suspensions are fully adjustable and can provide with a plethora of finely-tuned setups for any rider and any riding style on a variety of surfaces. The Kayaba Air Oil System fork and the lightweight, but rigid frame are responsible for the easy handling of the 2006 Kawasaki KX250 even through the sharpest turns.


2008 Kawasaki KX250

The 2007 Kawasaki KX250 is a dirt/ motocross bike powered by a 249cc single-cylinder, liquid-cooled 2-stroke engine capable to deliver more than 58 hp. While the bike's nature is clearly intended for racing purposes, it therefore lacks a headlight and blinkers, being thus illegal for street use. You can enjoy it on the dirt tracks or mountain trails, or non-public roads, however. Given the aggressive and explosive character of the power unit, the 2007 KX250 comes with petal disc brakes for dependable stopping force, while the design of the very rotors keep them clean, with no dust or mud diminishing their capabilities. The perimeter steel frame is both light and rigid, offering great handling, especially with the 2007 KX250 weighing only 97 kg (214 lbs). Fully-adjustable suspensions make this bike suitable for pretty much any rider and any riding style on a variety of surface types.
