I believe that might be the case.
In one direction, I saw some videos from a German bloke (and his mates) from the black forest region. There are some really great roads there. Their theme seemed to be "safe" lines, i.e. staying in the middle of the lane, and getting as much lean angle as possible. Wankers, in my opinion.
I'm more interested in a clean line from one corner to the next, and positioning my body weight so that the bike "hangs" in the corner.
I developed the habit of hanging off a bit, firstly, in the eighties and early nineties, when, amongst others, a certain K. Schwantz was riding a two-stroke Suzuki with the number 34 on the front. If one watches him for a while, it is obvious that your bum has to be anywhere but on the seat to get throught the corners "properly".
Secondly, I was doing it on a 1976 Z 900. That thing really did benefit from getting the rider's weight down beside the bike a bit. Middle '70s japanese frames and suspension where, shall we say, sub-optimal, and creating a "counterweight" was a good idea.
On top of that, my vision. I think I mentioned here recently that I don't have 3D vision. Over the last several years, I have come to the conclusion that I personally can "see the line" better if I am looking past the handlebares into the corner a bit from the side. Parallax, or something.
I lost the habit of moving in the seat through not riding for about 10 years, then a Honda CBX 650 E soft-chopper, followed by two full-dress Kawasaki GTR 1000s. I'm currently working on getting back into the habit, and have established that, for me, it is better when I hang off a bit. Doesn't have to work for everyone, though.
And yes, the Police are fast. They are professionals, what do you expect.
