2012 Kawasaki KLX 140

Enjoying the thrills of motocross riding doesn’t have to involve using a high-powered bike. Sometimes, you’re actually better off with a simpler and easier to handle bike like the Kawasaki KLX140 .

As a multi-talented ride that provides a steady flow of power, the KLX140 is the kind of bike that riders of all shapes and sizes will come to enjoy. Whether you’re a novice in the game or a seasoned veteran, the accessibility and usability of the KLX140 is a true hallmark of this compact, straightforward dirt bike.

The KLX boasts of a high-revving, smooth and surprisingly quiet 144cc engine that’s remarkably simple to use, thanks to a manual clutch and a five-speed, close ratio transmission. Combine that with a high-tensile steel perimeter frame covered by KX-like shrouds, a two-tone seat cover, and sharp, aggressive body work, and you have a bike that’s built for any and all occasions. The KLX140 also boasts of a roomy cockpit, overall control layout, and a narrow footpeg/frame relationship – including wide and comfortable footpegs – making it easy for riders to move around without worrying about losing their way.

Handling the suspension duties for the KLX140 is a 33mm telescopic fork featuring custom-tuned spring rate and damping settings. In the back, a UNI-TRAK linkage equipped rear shock featuring 5-way preload adjustability provides a smooth and controlled ride while lightweight RK EXCEL aluminum rims and advanced braking components make for a completely versatile bike. A large 220mm front disc and 27mm twin-piston caliper at the front and 186mm rear disc provide serious stopping power. Both utilize petal shaped rotors, which help clean the brakes and reduce unsprung weight for better wheel control.

Infosport Bike----"The KLX140 delivers an ideal combination of size and performance, while the equivalent of great fun for children and adults."


I agree! This one looks easy to use and ride. And i like it better when it has that spring rather than those without. Much lighter bike for a motorcross is much reliable to use.
