2018 Kawasaki KLX140G Totalmotorcycle.com Features and Benefits


The KLX®140 motorcycle is available in three model variations, and is designed to provide a natural terrain experience with memories to last a lifetime. The powerful 144cc, 4-stroke, air-cooled, single-cylinder engine features an electric starter and keyless ignition. Its broad and smooth high-revving 144cc engine utilizes a manual clutch and 5-speed transmission to offer an efficient and user-friendly feel. The clutch features a spring damper resulting in a progressive, 2-stage engagement that facilitates half-clutch use when riding at extremely low rpm or idling speeds.

The chassis consists of a rigid box section steel perimeter frame that is shared on each of the models for excellent handling characteristics, as well as a lightweight aluminum swingarm. Up front you’ll find 33mm telescopic front forks, which offer 7.1” of travel on the KLX140 and KLX®140L models, and 7.5” on the KLX®140G. On the KLX140, the single rear shock has fully adjustable preload and is held up by a Uni-Trak® rear linkage, while the KLX140L and KLX140G also feature 22-way rebound and 14-way compression damping adjustment. Additional travel can be found on the rear of the KLX140G (7.9” compared to 7.1” on the KLX140 and KLX140L).

Showing the KX™ heritage, a large 220mm petal-shaped front rotor with a twin-piston caliper and a 186mm petal-shape rear rotor provide plenty of stopping power. The KX influence continues with the wheels, which have strong die-cast hubs and lightweight aluminum rims. The KLX140 uses a 17” front and 14” rear wheel, while the mid-sized KLX140L motorcycle is equipped with a 19” front and 16” rear wheels to accommodate taller riders, providing extra ground clearance on the KLX140L. The KLX140G comes equipped with full-size off-road wheels and tires, using a 21” front and 18” rear.

With three different models to choose from, riders can easily select the bike that best suits their stature, starting with the KLX140’s 30.7” seat height and slightly larger KLX140L (31.5”). The  KLX140G motorcycle is the perfect fit for taller riders who want to experience the KLX lineup, thanks to its 33.9” seat height and spacious ergonomics.
