Well, yes, this is an old posting but I decided to add my two cents rather than start a new thread. Hopefully, this will be of some benefit to AK550 owners who are interested in an aftermarket windscreen. I first bought the Puig windscreen and it wasn't much improvement over the stock screen. Recently, I got the Givi sport touring screen and it's a huge improvement. There is a tradeoff however in that I have to look through the top of the screen, something I've never liked, but the wind protection is totally worth it (IMHO).
