2012 Kawasaki KX™85
The 85cc-class mini-motocrosser has long been the training crucible for the world’s top racers. For much of that time, Kawasaki’s KX™85 has been at the forefront. The level of technology, power and berm-busting capability packed into this 152-pound rocketship is mind-boggling, and the way it can tear up a motocross track in an expert’s hands must be seen to be believed. It’s nothing short of a youth motocrosser’s dream machine.
