That's bad news. I've got Swmotech setup on my FZ1, and just ordered one for my new(to me) K1200s. The setup on my FZ is super tough and the Givi E360s can make good frame sliders. I hope it works out the same for ze german. I've got the "sport" panniers on it now, and you're right, even expanded there's not a ton of room in them.
