Sounds to me like the Multistrada fits your requirements the best. I'm assuming you've ruled out others more similar to it, like the BMW GS, for example. The scratching on the Multistrada is second to none. Don't worry a bit. The first thing I noticed when riding one is how much it likes to be healed over, and hard. I rode an early one, and the seat was hard and got heat from the exhaust. I hear the seat's been softened; dunno about the heat. I have to say this, when I got back on my R1100S, I liked it a lot better. You owe it to yourself to give the boxers a good thrash. Used '04s are a bargain...

I've read some good things about the 620, but I can't help wondering if the lack of power might become more pronounced over time. I also agree with Eric on the 1000s DS. The Ohlins f&r are more than worth the price difference, and are infinitely rebuildable. As they say, "A job worth doing is worth doing right."

The 675 is just in it's first year of production, and Triumph doesn't seem to get their bikes sorted out right away. That riding position will get old on a long trip; dunno if they offer hardbags, either.

The Falco's a great bike; a sleeper. That Rotax engine is a gem. You might want to raise the bars on it, if possible. Dunno about hardbags. The Futura is also worth considering; it suits your requirements better.

Another very dark horse is a Cagiva Gran Canyon. It's got a Ducati 900cc air-cooled engine in it (and hard to get at, I hear)...

(edited to say 900cc)
