If the standard KLX™ 140 with its 17” front and 14” rear wheels holds appeal for both young and old, the KLX™ 140L incorporates all of its many features, yet packages them in a slightly beefier version, giving taller riders something to crow about. The 19” front and 16” rear wheels on the L-version are only part of the story, as its also equipped with a more performance-oriented , reservoir-type shock that the larger, more experienced rider will quickly appreciate.
