My three-year old X1100C with 6,500 miles (800 hours) developed a crease tear at about 4,000 miles (my X900 did the same thing). I tried to make a repair using Permatex Vinyl Repair Kit, but that was only marginally successful. I finally decided to try Besezx Leather Repair Tape and after a few months I can report that it is holding up well. I then used it to repair some worn areas on my 20+ year-old B7800 and I am pleased how well it seems to be working. The middle two pictures are of the repairs on the B7800 and the 4th picture is from the X1100C drivers seat.
