Am on my first F6b Black. Just got it a month ago 2013 with 8500 miles. I like it so far and it will probably be my last bike at my age, 65yrs.
I say my last because I don't need to look any farther. It does anything I ask including pulling a trailer like it aint even there.
And the stopping power is awesome. Its wicked fast for its size.
I'm in love.
