I currently own a like-new 2002 K1200RS and a 2008 K1200GT (and actually prefer the RS, in most respects, to the GT, which I find abysmally vanilla in character). Each weigh about 635 pounds, gassed (just checked it online). That means the new GT is 70 pounds heavier than each of those.
When they did the re-design of the older K1200 series (of which my RS is an example), the goal was to reduce overall weight. What the heck are they thinking when they introduce a new GT that is heavier than the past two generations of GTs? This goes completely against their design philosophies of the past six years. I don't have the strength to keep these larger, top-heavy (no matter what their spin says to the contrary) BMW touring bikes upright.
Will the 1300 GT be discontinued? I suspect its days are numbered.
