In my opinion, the Ten is very well set up for overlanding "out of the box" (with the possible exception of the suspension). I was very happy with it on that trip, but I started tinkering, and once you start tinkering, it is hard to stop! So, I am a good way through a few modifications to the stock bike:
#Renthal 613 high bend bars. If Mongolia taught me anything, it was that standing on tricky off road sections is advisable. The stock bars were just a bit too low for a tall fella like me when standing. The 613s give an improved riding position when stood on the pegs. I could still do with a bit more height on the bars, but as I don't like bar risers; I may go for the lower (adjustable footpegs) at some stage.
#Kahedo high seat. The stock seat is crap; OK with an airhawk, but still crap on any long distance ride. So I shelled out for the Kahedo high seat (I am tall!). In all honesty, I wasn't convinced at first. But after several months with it, it has improved comfort considerably (just as well, as my airhawk has a puncture and I can't find the repair kit that came with it). The flat profile of the Kahedo allows you to shuffle around while riding and alleviate any pressure areas.
#Exan single exhaust. The stock set up is VERY heavy, and that was my main reason to switch to a single can. The improved exhaust note is a bonus! The only downside was that the popping/banging on deceleration was crazy loud. So that lead on to the next mod:
#AIS pipe blocking. Simple enough procedure in the end. I couldn't get to the clamp to remove the AIS pipe to plug it. But a recommendation (by the ever reliable Pleiades on XT660.com) to use a Hoffmann clamp to block the pipe worked a treat and now, no more popping!
That is where the bike is up to now; but there are more mods to come. Probably.
