Have the Schuberth E1 and really like it but I do get some visor buffeting at over 70-ish. Did a mod today to see if the visor will stay a little stiffer and not buffet. I am 6’1” and ride a BMW GS1200 with a Z Tech screen for reference. So in trying to stiffen the visor I ran some threaded rod through the visor with nylock nuts and a sleeve around the threaded rod for a more finished look. I filed the rod so it would seat up in the inside of the bill. Not 100% on seeing the nuts on the outside but we will see if it improves the ride.
