Featuring confident handling, KLX140R motorcycles are the ideal entry into off-road riding. The easy-to-ride KLX140R lineup offers a 144cc engine, plush suspension, and push button electric start, making for great trailblazers.
Confident Handling
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 larger wheels (19F, 16R), taller seat height (800 mm) and higher 255mm ground clearance, while the KLX140R F trail bike features full-size wheels (21F, 18R) and 315mm ground clearance.
SM
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 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.
*KLX140R F rear disc is ø190 mm
