So I Haven't test ride either yet, I will this week but I could use any advice I can get. Its important I get a bike my wife and I can take long trips on. The Forty-Eight has a 4.2 gallon gas tank. The Fat Bob is good for two-up though, is the difference regarding riding two-up between the two going to matter enough? While I love the look of the Forty-Eight, the Fat Bob may be more comfortable and I still love the look. The Forty-Eight looks better in my opinion.
