I had a low side crash with an E460 on my old ST1100 (at about 45-50mph). I had the side bags off that day so the Givi actually took all the force in the back. The bag stayed on, but I hit with enough force that the back frame rails actually got twisted.
The Givi locking systems work really well if you get them "clicked" in.
