Hey Pal,...how's it going?
That is a custom windscreen for sure and was made for the person/member I bought the fairing {and tour pak} I bought it from. I think, but could ask the guy where he had it done. He lives in Medicine hat Alberta. It is wider and does a great job of cutting the wind. That along with the dragon fly wings and the large lowers does a complete job on any buffeting. I also have hard lowers below the plexiglass lowers. That helps too I think.
Here is a photo ...I think it's about 2 inches wider at both sides.
I hope that helps... Thanks for looking !!
