In reply to abr1966:
I did 30,000 miles in 2 years on a Versys, very capable bike indeed. I only changed it because the Mrs wanted to start touring with me and I'm a big lad and she is not a small lady.
I then did 20k on a BMW 1200 GS in 2 years, followed by 30k on. Triumph Explorer and now I'm in year 3 of ownership of a BMW 1200GS Adventure.
The Versys was the least prone to corrosion followed by the Triumph and the BMW's are both shocking.
I had a few mechanical problems with the 1200GS but nothing with the tigger but when I dropped it in the snow the plastics were a second mortgage.
I would probably look at the Versys, the tiger 800 low (my friend is a triumph test rider and tested that bike prototype on our holiday round the alps) and also the Yamaha tracer (I think it's the tracer)
If your looking for 2 up big mile touring though I love the 1200 cc bikes.
