Good choice Garfield. I've just done 1k miles on my Tiger 1200XRT, had Gen1 and Gen2 Explorers before it. It really is a stonking piece of kit. Yes it's a little top heavy, but only any hindrance when trying to move it around and then it's not that bad. The quickshift and blipper is a proper fun piece of kit and really does add a lot to the ride.
I did give the latest GS a good 2hr test ride before deciding on the Tiger. The GS was, is, a very nice bike, but I won't be doing any offroad work and felt the Tiger was a much more capable road bike. Finish quality also appeared to be a step up from the BM.
Enjoy.
