2012 KAWASAKI KLX 140L, 2012 KAWASAKI KLX140L, A Capable Dirtbike for Fun and Adventure Taller riders will appreciate the KLX⿢140L, which features taller wheels ⿿ 19-inch front and 16-inch rear ⿿ than a standard-spec KLX140. It incorporates all of the virtues of the standard 140, including an engine that provides a steady flow of power that new and seasoned riders will enjoy. The 140L model is equipped with a more performance-oriented, reservoir-equipped shock, because it⿿s popular with a larger, more experienced crowd. Of course, the standard KLX ⿿ with 17-inch front and 14-inch rear wheels ⿿ is still a great option for novices and smaller riders.
