This one looks staged. Look at the front tire. It is turned out, like it would be if it were about to tuck and slide. There's also almost no deformation of the front tire from the weight of the bike at the contact point. Also, the pegs usually touch first, then the bags, and finally the engine guard. When the guard hits, that is usually followed almost immediately by the front or rear losing traction and a crash. MotoGP bikes with HOT and STICKY tires max out around 60-61 degrees of lean. That guy looks like he's at about the same angle, if not more. The GS can lean a LONG way, even on the TKCs, but not like a MotoGP bike. His guard looks like it is on the ground. I suspect the bike is resting on the crash bar and bags, or he could be in the process of going down...
I wore holes through the lower leading corners of my Jesse bags on my 1150 GS and removed a good 1/4" or more of metal from the bottom outside of the foot pegs. The big never squirmed or acted like it was going to let loose. When things got tight and twisty, I'd rather have been on my 1150 GS than on a sport bike. It was very easy to ride smoothly and quickly because of the great handling.
In Arkansas running about 75 mph (look at the front tire squishing under the load). The peg was maybe 3/4" off the ground. I had to pull my toes in because they started scraping (early warning for peg down).
