I honestly don't know but I just did a Google search and found this. According to the guy who posted it, it's a Honda CBR bikini fairing. I bought it at a swap meet this year for $15 because I thought it was cool looking.
The paint on the fairing fogged up again. I wish I had an actual paint booth to spray in. Well, another night of sanding and painting. Sprayed the tank again too. Hope to clear them both today. But before I did, I finished making a rear seat mount and mocked everything up. I really love the way this has turned out.
