I've picked up a new GS Rallye last Saturday, only done 240 miles on it, but I would say my Oct 2013 GS LC is identical to the new one on clutch/gearbox function, (I must have had a good one) although the keyless ride is nice, as is the excellent brake assist hill start function.
The suspension is a tad more refined, smoother over the speed bumps etc, also the heated grips actually work..
My old GS was one of the first models with the updated white springs & steering damper. Amazing bike..!
Hope this helps guys..
