2009 Kawasaki KLX250SF
Lightweight supermotard delivers quick reflexes and unlimited fun
For those seeking a nimble user-friendly bike with supermoto styling, Kawasaki has a solution in the shape of its new KLX250SF. Based on the KLX250S dual sport, the new SF model is specifically tuned to deliver maximum on-road fun. Its 17-inch wheels, radial sportbike tires, a big front brake rotor and lowered suspension give it an air of purposeful aggression.
Sporting all of the updates and refinements found on the freshly minted KLX250S, the new KLX250SF has reduced wheel travel at both ends, placing the center of gravity lower to improve on-road handling and enhance straight-line stability. This also results in a more planted feel in corners and a lower seat height. The change in setup offers a firm ride quality, thanks to a change in front fork oil level and revised damping settings for both the fork and shock.
These changes provide a reduction in pitching motions during braking and acceleration and help allow the rider to hold a consistent line during aggressive on-road cornering. However, the suspension is still supple enough to soak up most road surface irregularities and offer a smooth ride. The KLX250SFs fully-adjustable suspension features 16-way adjustable compression damping on the 43mm inverted cartridge-style front fork and 16-way adjustable compression and rebound damping on the Uni-Trak® rear suspension. Wheel travel is 9.1-inches front and 8.1-inches rear which strikes a happy-medium between long-travel off-road designs and short-travel sportbikes.
The KLX250SFs short wheelbase aids its already outstanding ability to hold tight lines and its rigid box-section perimeter frame provides excellent transitional response, thanks to its rigid steering head. Complementing the chassis is a lightweight aluminum swingarm with a highly-rigid D-shaped cross section and KX racing-type chain adjusters for precise chain adjustment.
The new KLX250SF employs convenient electric-starting for its compact, liquid-cooled, four-stroke, single-cylinder engine. The 249cc engine is mounted in a lightweight, high-tensile steel perimeter frame to deliver a low center of gravity and superb maneuvering on tight roads. A gear-driven engine balancer keeps engine vibrations at bay for greater comfort and less fatigue on long rides.
A 34mm semi-flat slide Keihin CVK carburetor contributes to quick throttle response and precise power delivery. It also helps to provide increased fuel economy. An evaporative emissions system allows the KLX250SF to meet strict CARB regulations, making it eligible for sale in all 50 states.
A six-speed transmission provides optimum gearing for most occasions and helps the rider to keep the 249cc engine at its optimum rpm. It employs a smaller 39-tooth rear sprocket to extend its high-speed capabilities beyond those of the KLX250S dual sport.
Negotiating urban traffic or blasting around a tight race track highlights another strength of the KLX250SF it keeps its cool. Incorporating dual lightweight, high-capacity Denso radiators and a shallow-footprint cooling fan provides an ample solution to potential heat issues.
New 17-inch cast aluminum wheels offer great handling, improved stability and the aggressive on-road performance sought by urban commandos and canyon carvers. The new wheels also allow access to a wide range of sportbike tire options. Aggressive riding on pavement demands powerful, fade-resistant stopping capabilities and the new KLX250SF delivers with a massive 300mm semi-floating petal disc up front clamped by a twin-piston caliper. The rotor is 4.0mm thick for increased rigidity, efficient heat dissipation, and optimum fade resistance. A single-piston caliper squeezing a 240mm rear petal disc compliments the big front brake.
Finishing off this package is a new set of aggressively styled ebony bodywork,
a comfortable seat and a handlebar which offers good leverage so riders can
flick the light KLX250SF side to side, or hold a tight cornering line with
a minimum of effort.
Riders seeking supermoto handling and modern engine performance in a lightweight motorcycle designed for exciting street rides will find it at their local Kawasaki dealership. The KLX250SF offers serious capabilities in a fun, easy-to-ride package, regardless of where the adventure takes it.
Authentic Kawasaki Accessories are available through Kawasaki dealers.
