Just drove a K1600 GTL this saturday.
Seems a lot lighter then it is.
Can pick the bike off of side stand with almost no effort.
The wet clutch is a nice change from dry RT's Very smooth.with little travel.
The left wheel control on handle bar is slick. (not sure what to call it)
Radio sounded ok.
Had it in rain mode. Did not notice any drive line slack that others commented on.
Shifted nice and smooth not clunky.
Plenty of torque (gobbs of torque) can make a turn at a crawl in 3rd or 4th with out shuttering (RT needs to be in 2nd)
Was following the sales man (on a K1200R) let him get way a head of me, them wind her up and was almost on top him in seconds (look down and i'm going 90mph)
Brutal even in Rain Mode.
Handles like an RT but lower.
Fit and finish perfect.
Tour pak is not stable period. Lots of movement.Looser than RT. (get real BMW)
Tour pak is way too small for a touring bike.
Thats it for dislikes.
If BMW addresses the tour pak issues i will buy one.
Also drove 2011 RT. Don't see any advantage over my 09 RT.
