I have been using this stick on visor (held by a couple of suction cups). I cannot remember where I bought it but it works fine and easily stows away when not needed. I originally got it years ago for a VX220 which also had no sun visors. Had a great blast down to Cape Cornwall (into the low winter sun) yesterday and it helped a lot. I seriously dislike the look of fixed visors on a Morgan.
