I am back and forth about this harness. After one 3 hour trip with this harness holding down my motorcycle on my trailer, the plastic buckle thing that is used for adjusting the width between the grips is broken on one side. I have since used the harness with no problems but it is a small concern to me and I feel like it could be a really bad day if it breaks completely. I also had to wrap shop rags around my grips the second time I used it because the first time it left a very undesirable pattern imprinted in my grips from the piece that wraps around them and is supposed to protect them. I would suggest looking for a more durable or better fitting harness if you're going to have your motorcycle on a trailer a lot. I don't think this harness does anything better than any other out there and this one is more expensive.
I've been using blocks of wood between the tire and triple clamp for years. After getting tired juggling the block and my tie-downs at the same time, I broke down and ordered one of these braces. SO much easier to use because the wings rest on the forks and hold it in place while I ratchet down the straps. It fits my WR250R perfectly.
These tie downs are great. You really dont want to have to crank the straps down too tight or they will not allow the bike's suspension to work while on the trailer. These straps allow you to just snug the bike down without fear the hooks will come loose from the anchors when going over a bump and the strap loosens. Great product.
