Nuthin wrong with the tank..
Nuthin wrong with the frame...
Does the tank work good with that frame.. NO, it does not, it takes something away from it.
note, you cannot tell this in the pics, last page. I have seen a few roadtests with pics at other angles, plus saw the bike in real life in Jan.
in bikes as in engine building, it is not always the sum of the parts that makes it a success, but rather how the parts fit together & work with each other....JMO..
