As far as I can tell this is a "parts bin" bike. They must have had a bunch of the 650 singles lying around. Add to that a pair of spaghetti leg forks (non-adjustable, cos they're cheap). Same steel frame as the older G650GS. Crappy rear shock. Warmed over slightly higher tech instrument cluster.
Don't get me wrong, the [old] F650GS (now of course rebadged as the G650GS) is a good little bike (I know, 'cos my wife has one and I'm the resident mechanic). But to call this thing a "new model" is insulting.
