Looking for ideas to get my bike a bit more winter friendly and wondered if anyone is running a full fairing or something with leg shields?

Remember where he lives..London.  Is your bike modified a la cafe racer?
Most of the Savages are still in their upright sitting origional form.  A full windscreen Enterprise by  Windjammer for example that protects head, torso and hands.  For lower body protection, I'd go with heavier waterproof riding pants..a pain to get in and out of but I don't think I've ever seen a Sav with lowers.  Kinda tuff with the single downtube frame.  Good luck on your search and post photos if you get something.

yeh stock with a cafe fairing would look weird  
Am looking at doing a mild cafe over christmas holidays so wondered if any rycas are running cafe fairings?
Lowers are an option but although I have now personal experience methinks they don't do a lot.

Dustbin?

My Memphis shades is enough to slow the bike a good bit. Add saddlebags and it's airbrakes..
A ski bib is insulated and works like a rainsuit for the lower end. Combined with layers,, it works down into low forties okay. If I was younger, I could get in the thirties.

Go for it ZSteele.  It would look great.  

I think they add these for wind resistance, not adding drag.  I think youll be fine.  I dont think Ive ever seen a naked bike in the superbike class.
