At 6ft 3in, I always struggled with windscreen turbulence (buffeting) on most of my bikes. The Stelvio I just bought is no exception. Tried both my Schueberth C3 Pro and an Aria full face. Both would buzz my head on any windsceen position. The PO was kind enough to include a shorty windscreen. Now the air around my head is clean and quiet. Don't really understand the need for a tall windscreen for all the issues it causes - turbulence, fog, rain drops on the back side, bug spatter, etc, it's definitely a personal preference that I'd rather have a short windscreen that provides clean air for my head and better helmet cooling. With the right rain gear, cold weather gear and visor cleaner a shorty works better for me. There are no markings on this unit so I have no clue who made it. It did have a large hand print sticker on it that I removed.
