2025 Kawasaki KLX140RF Totalmotorcycle.com Features and Benefits
Box-Section Perimeter Frame(KP)
• KX-based perimeter frame made of high-tensile steel increases off-road capabilities.
• Flat footpeg/frame rail relationship provides area to grip the frame with one’s boots for better control.
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 playbikes 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.
