Anchor the tie downs in the front corners, compress the forks, but when you arrive at your destination relieve the compression as it is not good on the suspension for extended period of time. if the strap are making body contact, use a towel or something to prevent marring, remember plastic will crack. Also use quality tie downs (I use ANCRA), why anyone would choose to use 3 dollars straps for their 6k bike is beyond me, and always tie the end in a knot for added security and to prevent it from flapping down the highway scratching your windshield while it blows around. After a few miles check the bike and ensure its secure and nothing has changed. One last thing is put it in gear. I would say turn off the gas, but we won't go there as its FI.
