I also use a condor chock plus 3 2x4s for under the motor and Ratchet it down tight so the forks don't compress. Works great.

 

The Wheeldock & Biker bar have my vote (so far).
I am liking the Wheeldock more for it versatility (able to use it in the garage every day).
Looking a little closer at it...

 

The best way since forever - Stand the bike up straight with the front wheel in some sort of device to keep it from turning. Straps around the bars, upper tree, lower tree whatever you can get them around best and cinch them down evenly a little more than half way. Then strap down the back firmly with two more straps. Tie off the strap ends so they don't flap around and beat up the bike and off you go. No movement, no damage to anything no big deal. Don't over think it, don't make it out to be more than it is.

 

What bike?

 

This is how I do it. Works on all bikes (except springer) and does not compress the front suspension, allowing it to function as normal. Condor wheel chock makes loading a one man process. Rear strap location really varies a lot depending on the bike, does it have bags etc, but I always include to rear strap to keep the tail from wagging. you want a connection to the frame first, if not possible, swing arm next, if that is a no go I would reluctantly look at the fender/sissy bar support.

I am not a fan of utilizing the handlebars as a tie down point, rubber mounts in the upper trees, things move, bend etc. Just not a secure location. My opinion.

 

 

Not like this:

 

Meh, that should buff right out.............

 

Best way.....get the help of a second person.

Wheel chock is a good idea yet not always available, so make sure to bring front
tire all the way to the front of the wall of the cargo hold.
Strapping to handle bars instead of over the lower triple clamps is my votes.
Proper tie downs and extension straps to go over the handle bars are vital.
Compress the forks 3/4 of their travel, almost to its full travel.
IMO only need to tie down the front.
But, I have never traveled with this setup cross-country so there may be
better advice, except for my first sentence above which I think is # 1 best way.

 

I bought a pair of "tank straps" and a harbor freight wheel chock, similar to a condor, and use this guy's method to tie it down. Towed my 2018 electraglide ultra classic 1200 miles round trip like this on my utility trailer and the bike never moved. It felt solid with the trailer, but the suspension was able to absorb any bumps in the road.
I did add one strap to each rear floorboard just to keep the rear end from moving.
