As far as I'm concerned, the motorcycles gas tank, makes or brakes the look of the bike. It's the focal point of the bike and it has to balance form and function perfectly. Once in a while, you run into a production bike with a tank that really stands out. One such tank is the the cb450 black bomber tank and another is the rd400, both of which are favorites of mine. Perhaps lesser known due to the bikes stock form being a bit...forgettable, the xs750 tank is what i consider to be one of the more beautiful production bike tanks ever made. I always thought it would look great on other bikes and now I see that i'm not the only one who noticed.
