2014 Kawasaki KLX140 Review

2014 Kawasaki KLX140

Off-road riders and mini-moto enthusiasts don’t have to settle for simple one-size machines with limited performance and cramped ergonomics. Kawasaki’s KLX140 has opened the door for a wider variety of riders in the small displacement off-road arena…

High Performance Has Never Been More User Friendly

Just like its smaller KLX®110 dirtbike cousins, the robust KLX140 will tame the toughest off-road conditions while remaining flexible enough to maximize off-road adventure regardless of rider age or skill level. Its moderate 30.7 in. seat height means the KLX140 will easily fit shorter riders who are looking to ride a real dirtbike.

Thanks to the convenience of its electric start, bringing the KLX140 to life is as simple as pressing the power switch and thumbing its start button. Its power switch includes an internal LED to remind riders when the ignition is on, preventing accidental battery drain. Its smooth and powerful 144cc four-stroke engine is easy to manage via a progressive manual clutch and five-speed, close-ratio transmission. A progressive clutch means that younger and beginning riders can more easily get the hang of shifting and clutch use, and half-clutch can be used at extremely low speeds to simplify the learning process while offering a direct feel and tremendous durability.

The KLX140’s high-revving 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. A roomy cockpit, overall control layout and narrow footpeg/frame relationship – including wide and comfortable footpegs – make it easy for riders to move around while aboard with a minimum of effort.

A 33mm telescopic fork featuring custom-tuned spring rate and damping settings handles suspension duties up front. In back, a Uni-Trak® linkage-equipped rear shock featuring 5-way preload adjustability provides a smooth and controlled ride. To provide even greater options for growing riders, the KLX140L’s more advanced, reservoir-equipped shock easily fits the standard KLX140.

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 exceptional stopping power. Both utilize petal shaped rotors, which help clean the brakes and reduce unsprung weight for better wheel control.

Bottom line- The KLX140 delivers the perfect blend of size and performance, all of which equals big fun for kids and adults alike.

Authentic Kawasaki Accessories are available through Kawasaki dealers.

2014 Kawasaki KLX140 Features and Benefits


144 cc air-cooled, single-cylinder engine

– Reliable and easy to use lightweight engine is simple to operate and maintain

– Engine revs easily and allows riders to use the engine’s full rpm range up to the rev limiter at 10,500 rpm

– Exhaust pipe is curved to achieve optimum length for good power characteristics

– Quiet muffler is equipped with a USFS-approved spark arrester, meaning the KLX140 can access designated public off-road riding areas

– 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, while an umbrella around the main jet traps fuel when riding on rough terrain or 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, which acts like a shock absorber

– Float material is rubber instead of plastic

Close-ratio 5-speed transmission

– Close gear ratios help the acceleration performance of the KLX140

– Shift lever features a ball bearing design for easy shifting like KX™ models, and has a folding tip for reduced crash damage

Progressive manual clutch

– Manual 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 better clutch feel and 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 its older-brother, the KLX250S

– Aluminum swingarm is lightweight, strong and features a brushed finish just like the KX machines

– KX-style chain adjusters for ease of use and accurate chain adjustment

Superior suspension

– 33mm telescopic fork has spring rates and damping settings specific to each model

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

– The wave shape of the petal discs help clean the brake pads for more efficient braking performance and reduce unsprung weight


– Flat-shaped box-section of frame, long footpegs mounted close to the bike’s centerline and no kick-start lever combine to offer riders better feel and control

– Footpeg/frame relationship is modeled after the KX models for maximum leg grip

– Handlebar is rubber-mounted to reduce vibration felt by the rider’s hands

– Two-piece upper triple clamp and handlebar mounts allow easy installation of aftermarket bars
