2014 Kawasaki KLX140L, A More Robust KLX140 for Larger RidersWith its 17 inch front and 14 inch rear wheels, the Kawasaki KLX??140 holds plenty of appeal for both young and old, but it also incorporates all of the standard 140???s many off-road-worthy features, yet wraps them in an even beefier package that will stand up to the demands of taller and more aggressive off-road riders. The 140L not only features larger 19 inch front and 16 inch rear wheels and a taller 31.5 inch seat height, its suspension is also more performance-oriented, featuring an honest-to-goodness reservoir-type shock that larger and more experienced riders will quickly appreciate.
