The right size dirt bike for growing youth and youthful adults The days of settling for cramped ergonomics and limited performance aboard simple one-sized machines are over. With its 19 inch front and 16 inch rear wheels and advanced rear shock, Kawasaki’s KLX? 140L dirt bike is the ideal match for more experienced or longer-limbed fans of small displacement off-road machines. Its more elementary sibling; the 17 inch front and 14 inch rear KLX140, is a first-rate option for novices and smaller riders.
