84" is too short.
You will want the bike standing upright.
DO NOT let it be shipped on the side stand.
It will bend and or break the frame...
Get some good ratchet straps, 4 minimum, tie it low, like on the engine guards, and pull it forward and outward on the straps.
On the rear, get on the shock mount if possible and pull the strap rearward and out.
Like the picture, follow the little red road and the black one on the rear.. Pictures 2 & 3 are much better and closer up.

The front outside tiedown is right between my legs on the outside of the trailer.
This is the picture I wanted for the front.

This is the one for the rear.
