The standard screen creates a huge amount of buffet from the trailing (top) edge. This hits me squarly in the middle of the visor and the wind roar, noise and movement make it bloody unconomfortable. Thus that had been removed. This leave me with the buffet off the top of the front fairing in the chest, which is no problem up to 100mph then it starts to become a bit of a pain, especially after 100 odd miles. I am looking out for a double bubble type screen as these actually leave a smooth airflow off the top of the screen instead of an unstable vortex of buffeting air.
