I think I know exactly what Jim is dealing with. When you hang out at a dealership you will see guys who might be 5'8" and 150 lbs. soaking wet moving the bikes around the showroom or rolling them out the door while walking beside the bike. They don't seem to have any problems doing it, and I've never seen one of them drop one yet. I used to stop by a Honda/Ducati/etc. place where they moved 90% of the bikes out into the lot every morning and then back into the showroom every evening, and when it was quitting time those guys literally whipped those bikes back into the building with nary a hiccup.
I haven't personally gotten up the nerve to try this since my bikes broke the 700 pound barrier, and definitely not since I bought the SEEG. It has to be technique, because like I said some of the folks I've seen doing it in dealerships are smaller than me. Maybe it has something to do with not actually owning the bike in question that makes it so easy for those guys at the dealership.
