Clearview motorcycle windshields co. now has extended heights and widths for the 1400�s. You can get 2- 3.5� taller than factory and approximate 2-2.5 wider. There are also a lip at the top of the shield which will further assist is forcing the air up and over ones head. The price for lite tinted is 180.00 give or take a few bucks and the clear is around 20 bucks less. Also lowers will be available soon and will be superior to the factory ones as they will be 2.5� longer which will increase the air flow coming under shorter ones. Chris, the owner is going to cut me a prototype along with my windshield to test as they aren�t available until the testing is complete.
Just google CLEARVIEW MOTORCYCLE WINDSHIELD. I have used these guys in the past and they are great to deal with. DISCLAMER: I have no financial interest in Clearview.
