This is why I picked up a 990 SMT. Check out the 950SM thread in Road Warriors. Quite a few set up for touring. Also, with the 640 I put together, it has a little TT rack, tank bag, 18l tank and I have some Ortlieb bags for it. I've done a 3 month trip with that same set up. 2 up would still be a bad idea. I see what you're saying though. A full out MX bike converted to SuMo would not be pleasant on a long trip.
