WeiSen Passenger Sissy bar Backrest Mount Kit Compatible with 2018-2021 Honda Goldwing GL1800

the backrest installed rather easily once I made a few modifications. I had to add a couple washers to tighten the seat movement otherwise it was sloppy loose. The finish to the leather was rather glossy when the Honda seat is flat back. Strange the manufacturer couldn't see this. Had to cut a hole in the cap covering the mounting hole in the seat . Hard to get a nice neat cut with a razor knife in this tough plastic. My biggest complaint is that the seat sits too far forward. My back comes in contact with the rest before my butt is all the way back in the saddle. I like to lean slightly back into the rest as opposed to have it lean into me. Also since seat and surrounding area is flat black, the hardware on the seat should be also flat black as opposed to chrome and glossy black. I am contemplating sending this back and buying from Honda. More money but for a $25,000 bike I don't like cheap looking parts. These are very correctable problems that should be immediately addressed to make it a quality purchase.
