Introduction
A Capable Dirtbike for Fun and
Adventure
Taller riders will appreciate the KLX™140L, which features
taller wheels 19" front and 16 rear than a standard-spec
KLX140. It incorporates all of the virtues of the standard 140,
including an engine that provides a steady flow of power that
new and seasoned riders will enjoy. The 140L model is equipped
with a more performance-oriented, reservoir-equipped shock, because
it's popular with a larger, more experienced crowd. Of course,
the standard KLX with 17" front and 14" rear
wheels is still a great option for novices and smaller
riders.
Bringing the KLX 140L to life is as simple as pressing the power
switch and thumbing the start button. The power switch includes
an internal LED to remind riders when the ignition is on, and
preventing dead batteries. The powerful 144cc engine is easy
to manage via a manual clutch and a five-speed, close ratio transmission.
And a progressive clutch means that younger and beginning riders
can more easily get the hang of shifting and clutch use; its
progressive nature also means half-clutch can be used at extremely
low speeds. The clutch also offers a more direct feel and more
durability.
The KLX's high-revving, smooth and surprisingly quiet engine
is wrapped in a high-tensile steel perimeter frame covered by
KX™-like shrouds, a two-tone seat cover and sharp, aggressive
body work. The 140's roomy cockpit, overall control layout and
narrow footpeg/frame relationship including wide, comfortable
footpegs make it easy for riders to move around with minimal
effort.
A 33mm telescopic fork featuring custom-tuned spring rate and
damping settings handles suspension duty up front. In back, a
UNI-TRAK® linkage equipped rear shock featuring 5-way preload
adjustability and a remote reservoir provides a high degree of
wheel control, and is adaptable to the smaller-wheeled, standard-spec
KLX140 for added performance.
Lightweight RK EXCEL aluminum rims and advanced braking components
are another sign this is a serious off-road motorcycle. A large
220mm front disc and 27mm twin-piston caliper at the front and
186mm rear disc provide serious stopping power. Both utilize
petal shaped rotors, which help clean the brakes and reduce unsprung
weight for better wheel control.
Bottom line: The KLX140L delivers an ideal blend of size and
performance, all of which equals Big Fun for kids and adults
alike.

Features
At A Glance
· 144cc air-cooled, single-cylinder
engine is both simple to operate and to maintain

power
· Progressive manual clutch offers young riders the chance
to master clutch engagement and gear shifting
· Rear shock with piggyback reservoir has fully adjustable
preload, four-way compression damping and 22-way rebound damping
· Keyless electric starting via a starter button on the
handlebar; an LED indicates when the power button is on to help
prevent accidental battery drain
· Front 220mm petal disc and large-bore 27mm twin-piston
caliper (same size as those on the KX450F/250F) for strong and
easy-to-control braking
· Quiet muffler is equipped with a USFS-approved spark
arrester, meaning the KLX140L can access designated public off-road
riding areas
144 cc air-cooled, single-cylinder engine
· Reliable and easy to use lightweight engine is both
simple to operate and to maintain
· Engine revs easily and allows riders to use the full
rpm range up to the 10,500 rpm rev limiter
· Exhaust pipe is curved to achieve optimum length for
good power character
· The quiet muffler is equipped with a USFS approved spark
arrester, meaning the KLX140L can access designated public off-road
riding areas
· Oil-moistened air-filter is washable, reusable, easily
accessed and highly effective in dusty situations
· 31.5" seat height accommodates taller riders
Electric start
· Starting is via a (keyless) electric starter button
on the handlebar
· Orange LED light activates when the power button is
depressed, indicating that power is "ON"
· Digital CDI ignition helps ensure quick, reliable starts
Carburetor
· Oval piston-valve Keihin PB20 carburetor features
several Kawasaki-original modifications to provide stable fuel
delivery under rough off-road conditions
· Partitions in the float chamber keep the fuel from sloshing
excessively and an umbrella around the main jet traps fuel when
jumping
· Dual air vents help provide a stable fuel supply and
eliminate hesitation even when the bike is at extreme lean angles
· Needle valve is suspended on a spring that acts like
a shock absorber
· Float material is rubber instead of plastic
Close-ratio transmission
· Close gear ratios help the KLX's acceleration performance
· Like the KX models, the shift lever features a ball
bearing to ease shifting and has a folding tip for less damage
in a crash
Progressive manual clutch
· Manual clutch offers young riders the chance to
master clutch engagement and gear shifting
· A spring damper in the clutch gives it a 2-stage engagement
that permits half-clutch use when riding at extremely low rpm
or idling speeds, and helps provide direct clutch feel and better
durability
Box-section perimeter frame
· Ready for the off-road abuse, the highly rigid,
KX™-inspired high-tensile steel perimeter frame uses the
same upper tubes as the KLX250S
· Aluminum swingarm offers light weight, strength and
a hairline finish like on the KX machines
· KX-style chain adjusters allow precise chain adjustments
Superior suspension
· 33mm telescopic fork assembly has spring rates and
damping settings specific to the 140L
· Intended for use at a quicker pace, the KLX140L features
a rear shock with a piggyback reservoir fully adjustable spring
preload, 4-way compression damping and 22-way rebound damping
KX-style wheels
· Strong, high-grade die-cast hubs offer the same
durability as those found on the KX
· Durable, lightweight RK EXCEL aluminum rims on the 19/16-inch
front/rear wheels
Petal disc brakes front & rear
· Front 220mm petal disc and large-bore 27mm twin-piston
caliper (same size as those on the KX450F/250F) offer strong
and easy-to-control braking
· Rear brake uses a 186mm petal disc gripped by a 27mm
single-piston caliper
· Rear brake master cylinder features a large-volume,
unitized reservoir that contributes to stable braking and helps
ensure sufficient fluid pressure even when the brake pad wears
down
· In addition to helping reduce unsprung weight, the wave
shapes of the petal discs help clean the brake pads for more
efficient braking performance
Ergonomics
· Combination of the flat surface of the frame's box-section,
long footpegs mounted close to the bikes' centerline and no kick-start
lever add up to good grip and a high level of machine control
· Footpeg/frame relationship is modeled after the KX line
for maximum leg grip
· Handlebar is rubber-mounted for reduced vibration transferred
to the rider's hands
· Two-piece upper triple clamp and handle clamp foster
easy aftermarket handlebar installation
· Raised pattern on half of the grip surface offers more
control and comfort
