This is a pic from when I purchased my 550 a few years back. I generally follow the same plan each time I trailer a bike....wheel chock (cheapo from Harbor Freight) bolted through floor, two straps pulling forward, two pulling sideways and slightly forward, and two on the back pulling downward. I like to compress (1/4 to 1/2 way?) the suspension somewhat to reduce bounce. Your attachment points will vary depending on your bike and the type of bars you have on it. I prefer to hook the front straps to the handlebars up near where the triple-tree clamp is....but for example, when I had drag bars on the bike, there was no room to hook there and if I recall correctly I had to thread the straps around the upper forks between the trees. The bike came with an old fairing and crash bars, so it was attached to different points than I would use now....but it gives you a general idea. I didn't care about saving this old fairing in the pic....hence I just had the straps right up against it.
I also agree that the ratchet straps would be superior to the friction type, although I think I used a couple of those on this haul because that's what I had.
One thing to remember....watch out for loose strap ends flapping in the wind.....they will mark up your paint!

Happy towing!
