With its 17" front and 14" rear wheels, the Kawasaki KLX®140 holds plenty of appeal for both young and old, but it also incorporates all of the standard 140’s many off-road-worthy features, yet wraps them in an even beefier package that will stand up to the demands of taller and more aggressive off-road riders. The 140L not only features larger 19” front and 16” rear wheels and a taller 31.5 in. seat height, its suspension is also more performance-oriented, featuring an honest-to-goodness reservoir-type shock that larger and more experienced riders will quickly appreciate.





At A Glance…

• 144cc air-cooled, single-cylinder engine is simple to operate and to maintain

• Close-ratio 5-speed transmission makes optimum use of the engine’s 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 KX™450F/250F) for strong and easy-to-control braking

• Quiet muffler is equipped with a USFS-approved spark arrester, meaning the KLX®140L 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

• Air-filter is washable, reusable, easily accessed and highly effective in dusty situations

• 31.5-inch 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 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 5-speed transmission

• Close gear ratios help the KLX140L’s acceleration performance

• Like the KX models, the shift lever features a ball bearing to ease shifting and has a folding tip to help reduce the chance of bending the lever 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 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 brushed 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 Uni-Trak® linkage and 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 felt by the rider’s hands

• Two-piece upper triple clamp and handlebar mounts foster easy aftermarket handlebar installation

• Raised pattern on half of the grip surface offers more control and comfort

• Two-tone seat cover has a slip-resistant top surface for good grip when seated and smooth sides for excellent rider mobility when standing





Sharp, aggressive bodywork styling

• Box-section perimeter frame features advanced styling similar to that found on the KX racers

• Two-piece shrouds with ventilation holes inspired by the top-of-the-line KX race machines

• Fuel tank cover provides a flush transition from tank to shroud, and contributes to the bike’s high level of fit and finish

• Eye-catching box muffler design protrudes as little as possible from behind the side cover, and features a plastic muffler end-cap that offers a surface cooler to the touch than steel
