I know it's $60 more, but if you're in the market for this type of screen, you shoukd give the Dart Flyscreen a look. It's custom-made for our bikes, including a very handsome custom headlight bracket in a matching silver finish. It'll give you quiet air up to 90, it comes in smoke or clear, and the customer service has been outstanding.

Of course I have no interest or affiliation with Dart aside from liking the product. And I get $10 for every CB1100 screen sold in Coconut Creek FL.
