Nope, nobody, not never.
The stock tank is bigger than the stock tank on a DRZ-400. The stock tank is bigger than the first aftermarket sized tank for a DRZ (the 3.2). It surprised me that they would put such a BIG tank on the little DR-200 to begin with (we used to have one).
With 3.4 gallons and maybe 100 mpg (depending on conditions) it goes farther on a tank of gas than some cars. Propbably not much of a market for that conversion. Not saying you couldn't come up with some exotic mission that fewer than 100 people on the planet routinely ride, but if you really need that range, you are probably on a bigger bike to begin with!
