I have an F800ST 2010 that has a melted kinda boiled instrument cluster. I was thinking maybe my windshield magnified the sunlight while it was parked and displayed outside the dealership where I bought it. I did notice on another F800ST in that lot it had the same melted plastic on the same spot in the cluster.the other bike did not have a V stream windshield it was stock. Maybe the glass on the dealership magnified the sun aimed at the bikes? If anyone has thoughts on what could have caused this please do share.
