More fuel capacity for the sportster: Paughco Fat Axed.
I put about 40 miles a day on my sportster, and even at 53-55 mpg the stock 2.25 gallon tank (pic below) would only last 2 1/2 days before refueling.
So I bought a Paughco “Fat Axed” tank from Jireh Cycles (~$97), it was the biggest and cheapest bolt on tank for sportster I could find (4.2 gallons).
