Excellent, thank you so much! Was unable to find this Givi holder myself using Google. I did find some diy projects but the one linked by you looks perfect to me.
I thought about the magnet solution myself and looked up strong flat neodyme magnets to glue to the underside of the tank covers. As some small bags seem to have magnets in the main/middle part, and not only on the flaps, I hesitated, because that may not work given the led construction underneath.
Thanks again, Urs
