Your final drive (sprockets) can have quite an effect on the shift speeds. The shorter your gearing the quicker you'll go through the revs and speeds, the taller, the opposite.
I have a 20/39 setup and in town I rarely need to go past 2nd unless I'm hitting all green lights. On the freeways I get to 6th pretty quick and my revs are under 3k. The 1200 is plenty strong and that is not lugging the engine, it is smooth as silk and nearly silent. Even at those revs, a wick of the throttle makes the bike move smartly.
Generally, I stay between 3-4k. Getting onto the freeway I just run it up in 3rd a bit and then snick up to 6th and relax for the ride. This is usually 2 up although my rear seater is pretty light.
The Trophy 1200 is a wonderful engine, smooth and pulls hard right off idle. A lugging enging will shudder and with the Trophy that means heavier loads and under 2k.
In the end, just ride it and you find the sweet spot for revs that fit your riding style. Don't worry, the 1200 has 6 speeds so you can always shift up or down.
