I haven't seen any windshield options for the Supe. And I've been looking since the stock one it mostly for show, and doesn't do squat!
I imagine if you remove the stock one, then a universal windscreen will work. But then you have the stock mounting holes visible.
I would have thought, since the Super 8 has been around for several years now, that someone would have designed an aftermarket windscreen to replace the stock one. Unfortunately, I haven't found one anywhere. If anyone has found one, I wouldn't mind getting one myself.
