Hi !
I found the Video of my BMW K1600 GT Swing in this forum. Unbelievable !
Also i tried to translate your discussion with Google translator.

una trappola mortale! 
No, there are nearly 400 of these leaners in Germany and its really easy to drive with it.
Look for the Videos in my channel "Dolomiti 1&2" and "Swingxxclub"
by the way
My Name is Michael, also called Sir Arthur. I`m 53 years old and live in Nuremberg, Bavaria , Germany.
Since 2006 i drive a 3-Wheeler or leaner, called SWING. In the beginning with a BMW R1150R, since 2014 with a BMW K1600 GT Sport.
This combination (K1600 / Swing) was the first worldwide.
Another hobby of mine is recording my adventures with my GoPro 4 and i recently began to edit and upload them on Youtube.
If you like to procrastinate I`d recommend my channel on YouTube.

If you are interested in "Leaner" don't hesitate to ask questions !
I'll try to answer them and could also send some useful links to Videos / photos and so on.
But - sorry - i speak only german or english.... but like your beautiful Country.
Have a nice day
Michael
