144 cc Air-Cooled, Single-Cylinder EngineReliable and easy to use lightweight engine is both simple to operate and to maintain
Bore and stroke of 58.0 x 54.4mm
Engine revs easily and allows riders to use the full rpm range of the engine up to the rev limiter at 10,500 rpm
Exhaust pipe is curved to achieve optimum length for good power character yet remain unobtrusive
Quiet muffler is equipped with a USFS approved spark arrester, meaning the KLX140 can access designated public off-road riding areas
Oil-moistened air-filter is washable, reusable, easily accessed and highly effective in dusty situations
Electric StartKeyless electric starting via handlebar-mounted button
Orange LED light activates when the power button is depressed, indicating that power is ON and helping to prevent accidental battery drain
Digital CDI ignition helps ensure quick, reliable starting
CarburetorOval 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 which acts like a shock absorber
Float is rubber instead of plastic
Close-Ratio TransmissionClose gear ratios help the acceleration performance of the KLX
Shift lever features a ball bearing like the KX™ models, to ease shifting and has a folding tip for less damage in a crash
Progressive Manual ClutchManual clutch offers young riders the chance to master clutch engagement and gear shifting
Spring damper in the clutch provides 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 FrameReady for the off-road abuse, the highly rigid, KX-inspired high-tensile steel perimeter frame also 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 adjustment of the chain
Superior Suspension33mm telescopic front fork has spring rates and damping settings specific to each model
KLX140 rear shock features 5-way preload adjustability
More advanced KLX140L rear shock and reservoir can be mounted on the KLX140 for faster riders
KX-Style WheelsStrong, high-grade die-cast hubs that offer the same durability as those found on the KX
Durable, lightweight RK EXCEL aluminum rims on the 17/14-inch front/rear wheels
Petal Disc Brakes Front & RearFront 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
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 is maintained - 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
ErgonomicsCombination of the flat surface of the frames 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 available to the rider
Footpeg/frame relationship is modeled after the KX for maximum leg grip
Handlebar is rubber-mounted for reduced vibration transferred to the riders hands
Two-piece upper triple clamp and handle clamp fosters easy aftermarket handlebar installation
Raised pattern on half of the surface of the grips just like the top-class MX racers
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 StylingBox-section perimeter frame, with 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 high level 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
