These fairings have been around for a very long time and are sold under various names via loads of vendors for as low as $79. I picked one up used a number of years ago for a Bonneville. I took it off after one day. It now adorns my garage. They are generic/ universal and the fittings are rudimentary. They can certainly be fiddled with and strengthened through additional bracing, and painted to match the bike. But IMHO, they are best suited for a cheap and cheerful Cafe conversion of an old CB350 or the like. The CB11 is finished at a level, again IMHO, that would make this fairing stand out, not in a great way. But your ingenuity and results may vary, it's a relatively inexpensive experiment, and you could always sell it on eBay.
