2012 Kawasaki Dual Sport

Light and agile, the 2012 KLX250S have everything needed for riders seeking dual-sporting fun – a reliable liquid-cooled engine, long-suspension travel and a chassis designed for ultimate maneuverability on those tight trails.

The 249cc engine features the reliability of a 34mm semi-flat slide Keihin CVK carburetor, which not only provides crisp throttle response, but also assists in high fuel economy (think almost 60 mpg).

Further enhancing the KLX250S’ engine is electric start; this system is combined with Kawasaki Automatic Compression Release (KACR), which automatically lifts one of the exhaust valves at cranking rpm for reduced starting effort. The engine is hooked to a six-speed transmission geared for both the off-road terrain and highway speeds.

Speaking of the KLX250S chassis, Kawasaki says its “straight-line stability is enhanced by a rigid square-section main frame, yet its short wheelbase gives it outstanding turning aptitude. Complementing the chassis is a lightweight aluminum swingarm employing a highly rigid D-shaped cross section. KX racing-type chain adjusters allow for precise chain adjustments.”

Suspension travel is key to the function of the KLX250S, the machine featuring 10 inches of travel up front through the 43mm inverted cartridge-style front fork that features 16-way adjustable compression damping, and 9.1 inches of travel out back through the Uni-Trak linkage-type rear suspension that has 16-way adjustable compression and rebound damping, providing 9.1-inches of wheel travel.

The KLX250S’ overall chassis/suspesnion setup is enhanced by” 4mm-thick spokes in the 21-inch front and 18-inch rear wheels provide excellent rigidity for enhanced off-road durability. The KLX250S also stops hard, thanks to twin-piston calipers squeezing a 250mm semi-floating petal-shaped disc up front and a 240mm petal-shaped disc at the rear.”

Finishing the KLX250S dual-sport package is a standard aluminum engine guard to protect its crankcase during off-road adventures, a custom seat filled with firm urethane, aggressive bodywork and a carefully chosen handlebar pull it all together for long, comfortable days on the road and off it.

For those seeking dual-sport adventure, all under the $5,000 mark, the KLX250S is the have-it-all package, whether trekking the local trails or commuting downtown.

Following are the highlights, specs, color option and MSRP for the 2012 Kawasaki KLX250S.

2012 Kawasaki KLX250S Highlights:


  •  Compact engine design is lightweight and high revving, with a broad torque curve
