I also have the 800 XC and a couple of weeks ago, I had Rick Mayer make a new seat for me. He is in Northern CA but most of his business is out of the area. He changes the seat foam and will make it as narrow, wide, low or high as you would like. I have all my seats done by Rick and obviously, more than happy with him. The wife and I also have a couple of DR 650s. He redid both our seats and now we can do 350-400 mile days on the DR. Unheard of with the stock seats. Rick rides Iron Butt events but is also a licensed nurse so he understands both sides of the pants. One other thing about Rick Mayer seats. The wife had Rick redo her seat, after 18 months. Her style changed and needed an adjustment, which Rick did with a smile and the best customer care anyone could ask for. We went to Yellowstone a couple of months later, from NoCAL.
