2026 Kawasaki KLX140RF: THE TALL BOY.
Introducing the 2026 Kawasaki KLX140RF…
The KLX140R motorcycle is available in three model variations, each promising an off-road adventure packed with unforgettable moments. Powered by a robust 144cc, air-cooled, single-cylinder engine, featuring an electric starter and keyless ignition, the KLX140R line of motorcycles deliver reliable performance. The broad, smooth, high-revving 144cc engine, paired with a manual clutch and five-speed transmission, ensures an efficient and user-friendly riding experience. While the standard KLX140R sports a 17” front and 14” rear wheel, the mid-sized KLX140R L offers taller riders enhanced ground clearance with 19” front and 16” rear wheels. The KLX140R F is equipped with full-size off-road wheels and tires—a 21” front and 18” rear—for uncompromising off-road capability.

CONFIDENT HANDLING
LIGHTWEIGHT RIGID FRAME
A lightweight box-section perimeter frame made from high-tensile steel provides exceptional rigidity and strength. The narrow profile contributes to an easier rider grip and smoother movement on the bike. Working together, the highly capable suspension and lightweight chassis deliver handling that exudes confidence.
The KLX140R L trail bike features large wheels (19-in front, 16-in rear), tall seat height (31.5-in) and high ground clearance (10-in), while the KLX140R F trail bike features full-size wheels (21-in front, 18-in rear) and 12.4-in ground clearance.
SMOOTH POWER
ELECTRIC START
The high-revving 144cc air-cooled SOHC 4-stroke engine easily starts with the push of a button. Air-cooling eliminates the need for radiators, keeping the chassis slim and lightweight while a 5-speed transmission with manual clutch delivers smooth shifting and acceleration.
RELIABLE BRAKING
FRONT AND REAR DISC BRAKES
Front and rear disc brakes provide strong progressive stopping power. The 220mm front petal disc with a dual-piston caliper is complemented by a 186mm rear petal disc with single-piston caliper, inspiring confidence on the trails.
GET OUT AND PLAY
The Kawasaki KLX off-road series brings thrill and excitement to both beginners and seasoned riders alike, maintaining their reputation for being easy to handle, exceptionally capable on trails, and requiring minimal maintenance. For 2026, Kawasaki reintroduces its beloved KLX230R, KLX230R S, KLX140R, KLX140R L, KLX140R F, KLX110R, and KLX110R L models, catering to diverse rider sizes and riding preferences.
2026 Kawasaki KLX140RF Totalmotorcycle.com Features and Benefits
Electric Starter
• A keyless start button located on the handlebars makes starting quick and easy.
U.S. Forest Service-Approved Spark Arrester
• U.S. Forest Service-approved spark arrester in the quiet-running muffler allows access to designated public riding areas.
Close-Ratio 5-Speed Transmission
• Close gear ratios enhance the engine’s acceleration capabilities.
Progressive Manual Clutch on the KLX140R L/R F
• A spring damper is utilized to provide two-stage clutch engagement that facilitates partial clutch use when riding at extremely low rpm or idling speeds.
High-Level Suspension
• Sturdy front and rear suspension complements the highly rigid frame.
• 33mm front forks have spring rates and damping settings specific for each KLX140R model.
• KLX140R rear shock has 5-way adjustable preload.
• Since the KLX140R L/R F is likely to be ridden harder, the rear shock features a piggyback reservoir, threaded preload, 4-way compression and 22-way rebound damping adjustments. Both the shock body and reservoir are aluminum.
• The upgraded shock can be fitted to the KLX140R.
Full-Sized Wheels (KLX140R F)
• Full-sized wheels on the KLX140R F enhance handling and tractability over irregular terrain.
• Larger wheels increase ground clearance to help the KLX140R F better navigate trail obstacles.
• Chassis dimensions are optimized for larger wheels.
Petal Disc Brakes
• Unlike most play bikes with disc/drum combination brakes, the KLX140R models feature disc brakes at the front and rear for a higher level of brake performance.
• Petal disc design helps reduce unsprung weight while the wave shape helps clean the brake pads and increases cooling efficiency for more efficient braking performance.
Race-Inspired Ergonomics
• Rubber-mounted handlebar clamps reduce vibration transferred to the rider’s hands.
• The handlebar clamps are separate from the upper triple clamp, making it easier to install aftermarket handlebars.
• KXTM-style handlegrips with half-waffle design aid grip and rider control.
• Dual-texture seat cover uses a slip-resistant top surface for added grip when seated and smooth sides for excellent mobility.
