The Kawasaki KLX140, a 2011 model, is designed as an ideal transition motorcycle for riders moving up from smaller machines like the KLX110 and KLX110L. It caters to youthful riders by offering a robust suspension and a choice of wheel sizes (17/14 inch) to accommodate varying rider sizes and weights. The KLX140 models were developed with input from engineers and test riders of Kawasaki's championship-winning KX line, resulting in many components being derived from the KX line. This provides a superior level of off-road fun and ensures a racy continuity with other Kawasaki models through shared design elements.
The KLX140 is powered by a 144 cm³ 4-stroke, air-cooled, single-cylinder engine. This engine is designed for simplicity in operation and maintenance, offering high reliability. It delivers easy-to-use low-end power, which smoothly transitions to a top-end that revs out to approximately 10,500 rpm before the rev limiter gently cuts power. This smooth power delivery at high rpm enhances control.
Starting the KLX140 is made quick and easy with an electric starter, activated by a keyless On/Off button located in front of the handlebars. An orange LED light illuminates when the button is pressed, indicating that the power is on. The digital DC-CDI ignition system further ensures quick and reliable starting.
The motorcycle features a close-ratio 5-speed transmission, which enhances the engine's acceleration capabilities. The gear change position lever incorporates a ball bearing, a feature shared with KX race models, for improved shift action. A folding shift lever is also included to help prevent damage from trail impacts or mishaps.
Braking performance is a key highlight, as both KLX140 models feature disc brakes at the front and rear, unlike many playbikes that use a disc/drum combination. The front brake utilizes a large 220 mm petal disc with a twin-piston caliper, providing strong and easy-to-control braking. The 27mm pistons in the front caliper are the same size as those found in the KX250F/450F front brake systems, indicating a high level of performance. The rear brake features a large unitized master cylinder, similar to the larger KX models, for better performance, and an 186 mm petal rear disc gripped by a 27mm single-piston caliper. The petal disc design helps reduce unsprung weight and its wave shape aids in cleaning the brake pads and increasing cooling efficiency for more effective braking.
The KLX140's suspension system is designed to complement its highly rigid frame. The front features leading axle 33mm front forks with spring rates and damping settings specifically tuned for each KLX140 model. The rear suspension, particularly on the KLX140L, includes a Uni-Trak system with a gas shock, piggy-back reservoir, threaded preload, 4-way compression, and 22-way rebound damping adjustments. Both the shock body and reservoir are made of aluminum on the KLX140L, contributing to a lightweight yet strong setup. An aluminum swingarm further enhances strength while utilizing KX racing-style chain adjusters for precise chain slack adjustment.
The motorcycle's bodywork includes two-piece radiator shrouds directly taken from the KX250/450F models, designed for a flush fit with the fuel tank cover to facilitate easy rider movement. A box-shaped muffler design provides an aggressive appearance while being well concealed behind the side panel.
The KLX140 offers a progressive manual clutch system that utilizes a spring damper to provide two-stage clutch engagement. This feature allows for partial clutch use when riding at extremely low rpm or idling speeds, giving riders greater control. The manual clutch also enables riders to master full control of shifting, which is crucial for developing riding skills.
The frame is a KX-based perimeter frame made of high-tensile steel, designed to increase off-road capabilities. The flat footpeg/frame rail relationship provides an area for riders to grip the frame with their ankles, enhancing control.
Ergonomics are race-inspired, with rubber-mounted handlebar clamps that reduce vibration transferred to the rider's hands, improving comfort and control. The handlebar clamps are separate from the upper triple clamp, making it easier to install aftermarket handlebars. KX-style handgrips with a half-waffle design further aid grip and rider control. The dual-texture seat cover features a slip-resistant top surface for added grip when seated and smooth sides for excellent mobility, allowing riders to move freely on the bike.
The Kawasaki-tuned 20mm Keihin PB20 carburetor has been modified by Kawasaki engineers for improved performance during hard off-road use. Partitions in the float chamber and a main jet umbrella help minimize fuel sloshing, ensuring a more constant fuel supply and preventing engine bogging over rough terrain. Dual air vents maintain a stable air supply even when the bike is leaned at extreme angles. A rubber float with a higher specific gravity than plastic helps maintain a more precise float level, and a spring-loaded needle valve stays centered in the needle jet for better fuel flow and durability.
The air-cooled, single-cylinder engine is inherently simple in design, which generally translates to easier maintenance compared to more complex liquid-cooled engines. The high reliability of the engine also suggests fewer unexpected maintenance issues.
The keyless On/Off button and digital CDI ignition contribute to reliable starting, reducing potential troubleshooting related to starting systems.
The folding shift lever is a practical feature that helps prevent damage from impacts, which can reduce the need for repairs or replacements after minor spills or trail incidents.
The design of the petal disc brakes, with their wave shape, not only enhances performance but also helps clean the brake pads, potentially extending their lifespan and reducing the frequency of cleaning or replacement.
The separate handlebar clamps from the upper triple clamp simplify the process of installing aftermarket handlebars, making customization and maintenance of the front end more accessible.
Kawasaki offers an extended warranty and insurances, providing peace of mind for owners regarding potential future maintenance and repair costs. Authentic Kawasaki Accessories are also available, ensuring that any replacement parts or upgrades meet the manufacturer's quality standards. Information on these accessories can be found on the Kawasaki website.
