Yep, Unadilla's notorious for its rocks...even though they're not nearly the issue that they were a few years ago. But that doesn't mean that the teams don't do all they can to prevent rock damage...like this extra layer of tubing over the exposed section of radiator hose on James Stewart's YZ450F. we also spotted some addtional plastic screens in front of the radiators on the Monster Energy Pro Circuit Kawasakis.
