Reviving this epic thread. I replaced the rear on my 690 Enduro yesterday for the first time with a new MT-21. As it was my first time, it took me more than 2 hours, but now I know what to do and it should be way less than that next time. I used two of the 15" Motion Pro levers, one Motion Pro Bead Buddy, and another shorter MP tire lever and the rim protectors (damn those black rims!) No one's brought up the Kaurit Tire Mounting tool or the copy made in the US, the Baja No Pinch tire tool. They look pretty good if you're going to be changing tires regularly. One of the parts of the process that confounded me was after I had gotten the bead off on both sides, I had a hard time getting the wheel out. I pushed the rim down to one side, but it still took a fair amount of effort to get both beads over one of the rims so it was able to be removed. Is there a good trick to that?
