The 2011 MY YZ125 is a 2-stroke competition machine designed to provide premium performance straight from the box. The bike has a lightweight aluminium frame, with adjustable suspensions, a titanium rear spring and more race-derived components aimed at offering great maneuverability and explosive dirt performance.
The exhaust is also repackable from constant engine performance, while the "gripper" seat cover enhances rider contact with the bike, even in the most demanding of situations.
