I have moved my bikes over 5 thousand miles with work assignments and have always used nylon slings on the front as an anchor point. These are shown at the following link

What I do on the front is loop these on to the handle bars as close to the riser as possible, than I use the tie down ratchest to secure the bike, one on each side. I compress the suspense about 75% of its travel. (it helps to have someone else to hold the bike up) This has never come apart of losened off after all those miles. This also moves the S ring or hook away from the bike and elliminates the possiblity of a scratch / ding.
On the back I use one longer tie down strap put over the rear fender as close to the seat area as possible. Again I tighten this just enough that I can't move the bike at all (about 50% of the rear shock travel)
