Multi-time AMA Supercross and Motocross Champion Rick Johnson test rides the new, 2012 Kawasaki KXF 450. This is the same motorcycle that Ryan Villopoto clinched the 2011 AMA National MX Championship on, and helped lead USA to victory at the 2011 FIM Motocross of Nations in France. Rick said it best: " The most modern, and technologically advanced MX bike I have ever ridden".
