Installed the Yamaha brand windshield last night. It's pretty kick-a$$! Took a couple of hours to install and adjust. Ran it pretty hard over some rough country (all 3 positions) and worked great with no rattles or movement of any kind. It has 3 positions, full down, 3" prop, and flipped up and secured to the roof. I will say this,,,, if you don't like drilling holes in the hood or roof of your new machine, you may want to look at something else. And, the instructions are terrible. I love it tho.
