The Yamaha flip down windshield is about as durable as they come. I've had mine for two years and have yet to see any scratches or have any major issues. Mine even stays up while towing on an open trailer without any problems. In heavy rains water will drip down from the roof lip where the windshield meets it, which has been resolved on the new X4's that have a longer overhang on the roof. I don't know of any other flip down windshield that is comparable. There is a flip up windshield that seems to be well liked around the forum, but I was concerned with my vision being blocked with the tilt at my eye level being 6'3" tall.
