Has anyone considered the vintage full-fairings from Airtech? I'll admit that I'm partial to their aesthetics over the dustbins.
I'd probably be looking at the Dunstall, the Cronshaw, or the John Player Norton, due to the hand protection, and the fact that I sometimes need to ride to work at near-freezing temps. I'm wondering if they'd work with sport bars, or whether a person would have to go to clip-ons. And if clip-ons were necessary, would rear-sets then be necessary? (At least we wouldn't have to worry about shift linkages).
I'm not averse to crouching, and I've done up a rigid framework inside a tank bag for that.
I've adapted both an Air-tech 1/4 fairing and a Parabellum Scout fairing for an old BMW R65. I found that although the former looks cooler, it's not nearly as robust, and it doesn't provide the nearly the coverage that the latter does. But I guess that's where the full-fairing might come in.
I grew up lusting after the John Player Norton, so a part of me thinks that it'd be cool to slap one on a Zero, but then paint it with the original Norton colors and branding.
