After reading many good and bad reviews I decided to give it a try. Being able to fabricate I thought I could get it working for the price if there were any problems. Despite this, I received the item within 3 days, which was much faster than expected. The product is very high quality, it took a few minutes to assemble. I have a 900 pound Harley that I have had to tow in snow and ice. I borrowed an enclosed utility trailer from a neighbor but it only had 4 small D-ring attachment points. I took this block, pressed it against the header and inserted 2 bolts. I ran the bike into the wheel chock, it took a little effort to get in but the bike is very reliable. I then tied the bike down by the D-rings and the bike hasn't moved from that point. Pulling the bike out wasn't the job of one person with a heavy bike, it took two of us to lift and slide the bike out. I'm going to move the pivot mount about an inch, which should give me more leverage to get the bike out on my own. I will update after the change is complete.
