The KLX140 air-cooled single-cylinder engine offers a lightweight power plant that is both simple (to operate and to maintain) and reliable. The 5-speed transmission and the manual clutch are easy-to-operate by young riders if moving up from auto clutch models. The KLX140 push button electric start and engine run-off controls are on the left handlebar.
The aluminium swingarm on the KLX140 offers both light weight and increased strength. Like those on our KX machines, it features a hairline finish.KX racing-type chain adjusters allow precise adjustment of chain slack, helping to minimize drivetrain power transfer loss. KX-style wheels with strong, high-grade die-cast hubs offer the same durability as those found on our KX racers. Like our KX motocrossers, the KLX140 features lightweight RK EXCEL aluminum rims.
KX-based perimeter frame made of high tensile steel contributes to the high offroad riding potential of the KLX140.
33 mm telescopic front forks on the KLX140 are matched to the Uni-Trak rear suspension featuring a 5-way preload adjustable rear shock absorber for superb handling and offroad ability.
The KLX140L wheels are 19” diameter front and 16” diameter rear for a low seat height. Larger than kid’s bikes, and smaller and lighter than “full-size” play bikes, these KLX’s are a perfect fit for youths. The seat height 800 mm is a nice compromise between the smaller kids bikes and full-size machines. The KLX140L is recommended for youths up to 170 cm tall and weighing more than 55 kg.
