Racer X Tested: 2012 YZ125

Our YZ125 needed some repair after sucking some dirt and some questionable gas. Vertex Piston and Millennium fixed up the parts like new.  While we were at it, we added a few mod parts to give us a bit more grunt in the motor. Watch the video to see David Pingree shred on the freshly tuned bike, and see below for all the parts used.
