Actually, the Triumph Tiger 800XC is likely to be my ADV bike of choice when it comes time. I sat on one at the bike show and it's the only one I've been able to touch down on both sides with my short legs. Much as I loved the KTM 690 and 990 superenduro's they are just too dang tall for me. I was pleasantly surprised by the 800XC to find that it fit perfect.
The Triumph Tiger is a good choice but I am concerned about sourcing parts in my area since there is not a strong dealer network yet. I have a couple of KTM dealers fairly close to me and a good Yamaha dealer just up the road.
Lately I've found that with most bikes and most parts, I can get them as fast from online dealers as I can from my local dealers. It's quite rare to walk in and ask for a part and be able to walk right out. Usually they have to order it requiring me to make two trips to the store (if I didn't call it in) and ends up costing me more. Thus, I no longer fear the dealer network for parts since often I can get it cheaper shipped online and quicker.
That said, I have to give kudos to Motion Powersports here in Dallas. I DID walk in, ask for the clutch gasket for my FJR, and walk out with it in hand on the same trip, and got out for several dollars less than the cheapest place I could find it online.
