Oh damn, here we go again.
I will swim against the tide here and say that I HATE HATE HATE the Canyon Dancers. If you put enough strain on them to feel comfortable with the act of tying the bike down, you have put too much stress on the handlebars. As Fred W pointed out, they also "smush" the grips.
Use a front wheel chock if possible. These cost less than you might think and are well worth the price. Use soft straps to go around the bottom triple clamp, then attach your ratchet straps to the soft straps. This may require installing eyebolts in the trailer floor. There are several good ways to tie the rear.
Do not use the sidestand, you want the suspension to move. You also don't want to tie the bike down too tightly, you want the suspension to function.
Since the last time this subject came up there was at least one particularly belligerent jack ass who objected to my comment about Riding Instead of Trailering I feel compelled to add this just to irritate those with thin skin and no sense of humor:
I have no idea how you would tie one down. Mine has never broke down where I could not get it to the dealership. I cannot imagine trailering it otherwise.
