If you are truly overlanding the bike an extensive dealer network is key. If and when shit really hits the fan with any modern bike your not getting it fixed in a cardboard shack. For around home clearly this isn't a consideration. From my own experience the 800gs has been flawless but I also really maintain it. At first I thought I was going to love the Triumph but then I through my leg over one. The ergo's just don't seem right and maybe its just in my head but it seams a lot more top heavy. Lastly three cylinders has to cost more to maintain in the long run but only time will tell.
