I've fitted one - looks great but is hardly better than the clear standard screen as far as airflow is concerned. I'd look elsewhere if you want to improve airflow - my mate has fitted a Givi touring screen and he said it works well and looks good too:nerd:
I was in the Seattle Touratech store a couple of weeks ago and there is a new windscreen for the 2015 Multi in the catalog. I do not know if they have released it or if it is any different than the ones Ducati sells.
Look at the 2016 Touratech Catalog, pg. 649, P/N: 619-6220
