comfortable cruising speed for the 1050
what do you consider your comfortable cruising speed on the 1050 ST.
Me i regularly hit 100mph+ and sits there effortlessly even when loaded up with luggage etc.
infact before I know it, when I accelerate and get into top gear, I`m doing 100+
but what i`d like to know is, whats the optimum speed, to get the best out of the bike (fuel economy etc)

On good roads
Well Peirre.....obviously it depends on road conditions but
I cruise at about 130 to 140, I think shes only doing about
5000rpm at that speed.....in other words, just ticking over.
You can relax and enjoy the ride at those speeds, anything
faster I think you have to concentrate more and for the long haul
you need to be relaxed.

Agree that 80 to 85 is a comfortable touring speed, but you might pick up some attention in most parts of this country doing that.
The bike will run sustained speeds of well over a hundred, but I wouldn't if you want to keep your license. I have run my S3 for over a half an hour at 110 mph and it didn't even break a sweat.
Stick with 5 over the speed limits and enjoy the scenery.
Far as gas milage on sustained trips, I'm not sure but this weekend I am taking a long trip both today and tomorrow, so I will let you know how she does.

MPH does not = Better / Worse Gas Mileage
Good gas mileage works off of consistent throttle not just a certain MPH, the more consistent you can keep the throttle at one position ( IE 80-85mph ) the better gas mileage you'll get.
Poor gas mileage comes from accelerating and decelerating many times during a trip ( IE Traffic ).
So saying you're going to burn more fuel at 140mph than at 80mph isn't really relevant because at 140 you're going to get there quicker but burn the same amount of fuel as 80mph, at 80 you'll just get there in more time.
Did that make sense?
Point is be consistent on the throttle and you'll save gas.

My newbie experience so far, I get about 44 mpg running around 3500 to 4000 rpm around town and on the highway, the more the bike breaks in the faster I can run in any given gear "cruising", 4th 50-60 mph at that rpm, 5th 55-70 mph, 6th, to infinity and beyond.
After about 800 miles 3 grand was getting to the point where it felt like it was lugging it a little.
In 6th on the highway that range of rpm gives me about 75-85 taking a five mph error off the speedo.
Last time I was at the dealers and talked to the mechanic he said the sweet spot on these bikes was between 3500-4000 and 6K.

That's a BIG DITTO from me GS Beamer. 
Couldn't have worded it better.
FWIW I average 50MPG most of the time on my 955 and that's mostly quick mountain stuff, with a race can and free flow air filter.

The old rule of thumb is
three quarters of your red line. In other words...if your bike red lines at 10,000rpm, you can cruise at 7,500rpm.
On my Sprint, 75Krpm must be around 140 mph. I guess!
If you are concerned with fuel economy, just set your on board computer read out to instantaneous fuel mileage. On an even flat surfaced road, you can experiment with speed and gears to see what gives you the highest mpg.

To get the best gas mileage, tuck down completely behind your fairings. That will raise the instant on mine by quite a bit at any speed.

Tuck down instant mpg readings can be inversely proportional to rider girth.
