Introduction
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 KLX™250SF.
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 KLX250SF's fully-adjustable suspension
features 16-way adjustable compression and rebound damping on
both the 43mm inverted cartridge-style front fork and 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 KLX250SF's short wheelbase aids its already outstanding ability
to hold tight lines and its rigid box-section perimeter frame
provides excellent transitional response, thanks to it's 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.
