The product seems very sturdy and well made. They look great on my 2020 R1250GS and don’t seem to be obtrusive in any way. I installed the left side and really struggled with the rear bolts.After removing the BMW bolts the new ones didn’t seem to thread easily, and I had to put so much pressure on them to get them to turn that I was going to abort the process and put the stock bolts back in. Now, they wouldn’t turn easily either, and I had to lube them with PB blaster and back them out and clean off the threads and push forward bit by bit. They were not cross threaded. After getting the stock bolts back in place I backed them out and proceeded with the installation. Interestingly, the right side was a breeze and the bolts came out with just turning by hand, and the new ones went in easily. My guess was that the threads on the left were not correct from the factory for some reason, a BMW issue.
