There is only one thing, in my opinion, the F6C does markedly better than the B. Heat management. I suppose it's inevitable that the thing which does such a fantastic job protecting you from the wind, the fairing, also serves as a heat sink, but c'est la vie. It's not a serious issue, especially on a highway at speed, but any traffic riding and it is definitely noticeable. A little furnace-like in San Antonio. I'll take it, because everything else it does infinitely better for my riding style, body type, and needs.

But if you get a chance to ride an F6C in some heat, check it out. It's almost like being on an electric bike. The fact that there was zero heat to the rider was one of my favorite things about that bike.

I already love the B so much, I can only imagine how much better it's going to get when the weather cools a little.
