I have an 07 Fatboy which I will keep alongside the F6B. My fatboy has had a bit of engine work done to it. It is pretty darn powerful in its own right. Im not sure which is faster! I do like the Fatboy as its loud and powerful but it is never great on any type of long rides or when I want to fly down a highway at 75 or 80 to get somewhere. Then it has buffeting and lots of vibration. I love this 2013 F6B I just picked up. Its Fast, sounds great (vance and hines monsters?), smooth as silk, handles like a giant sportbike. I had a honda cbr600 and a triumph street triple ,both very very fast and i was speeding like a maniac so I sold them to break the dangerous habit of going 100+ every time I got on them. Love this new bike!!! What a pleasure cruizing at 75 with no vibration at all. Harley will be sitting till summer but ill use the F6B till they salt the roads ,then it gets put away!
