I'm not worried about the tank. It has to get better mileage than my old Speed Triple 1050 and I got 45 mpg outta that pretty regularly. 45 x 3.7 is a 166.5 mile range. I can live with that in a sport-bike. If they do ever come out with a touring version then hopefully you can swap tanks if you really want to. Im drinking the big time on this bike. I envision it as the next sv650. Cheap, powerful, light, and naked.
