Dunno how comparable the wind protection on the C14 is, but I'm quite happy with how the C10 was designed. It's close enough that if you have minor issues (toes, outside of legs, hands, face/helmet), that some relatively cheap additions can round that out nicely.
I just have a taller windscreen and grip heaters, but a few extra layers of socks and other clothing and I'm quite content for an hour or so in temps above 10 degees F. I have skinny legs, though...
That being said, after a bad day with an ice patch under a bridge last year, I am now part of the 'bike stays home when temps drop to freezing and below' camp. 35 degrees+ and it's game on though!
MamaKaw may not have gotten things perfect, but it's close enough for government work for me. Plus, it gives me an excuse to farkle. Getting that other 10% out of the Connie is much easier than if you start at, say 50% on that other popular US brand (no wind protection for starters). Plus, Connie parts are usually cheaper than BMW parts...
Now, I hear that guys are quite content in that air pocket behind the fairing on the Goldwing, however, but I don't see too many of those. Apparently the cool kids don't ride Goldwings...
