When I picked my bike up, I had to trailer it home. Somewhere I had read never to use the handlebars as an anchor point - I don't know anything about the suggested ties above. I will second the suggestion to take off the tip over plastic guards and use the steel tubing as an anchor point and to use the ratchets to get the bike up and off the side stand. I also tied the front wheel to the front rail of the U-haul trailer - this gave me lateral and fore and aft anchoring. I then used ratchet ties to secure the rear wheel - to prevent it from sliding to either side and to give me additional fore and aft reinforcement. Then I went back and doubled up the ties to the tip over guards. I checked the straps at every stop, and had no problems with movement or loosening ties.
Good luck! Have a wonderful trip!
