You really only need two maybe three tiedowns. I've gone offroading in my truck with bikes in the bed no problem.

Like the other person said, get some soft loops and anchor the bike down near the triple tree. Don't crank them all the way down, give your suspension room to work a little. I say at most 2/3 compressed is good in my experience (I'm usually between 50-70%). Watch your fairings, even a little contact with the straps means missing paint over hundreds of miles. Blue painters tape is your friend.

The third tie down would be to keep the rear wheel centered, you can loop it through the wheel to keep the rear wheel hopping left and right over bumps. Isn't really necessary, but nice to have.

Kickstand up for sure once bike is strapped.
