My GS Adventure (NOT GSA) is packing an almost 10 gallon fuel tank. The center fuel cell technology might be feasible, however it could be a troublesome leaker and with the lack of a real frame, space is also amazingly limited. Of course you know the battery is already under the fuel tank.
It loses it's luster when you see the cost versus the existing industry leading tank.
A centralised fuel tank may give better balance for day to day riding, but will in my opinion stuff up the load carrying ability for big adventures. Too much rear tyre load would equal rapid rear tyre wear.
