it is unrestricted you can do 500kmh if you wish, but there is an advisory speed
As above, you're not going to do any damage as long as you're not banging it off the limiter. Have done high speed motorway stuff on the GSA I can say that much over 80 fuel efficiency drops off alarmingly and your tourances take a right bashing (feel the heat when you stop).
My speeds would be around 85 - 90 mph (5k - 6k rpm) on suitable roads but I would like to do this for long periods (until I get knackered or bike needs fuel).
I just wanted to be happy in my mind that I was not going to cause any issues in the long term when the bike is not really a sport bike or a full blown tourer with overdrive etc.

Not mentioned, but on my 1100 when cruising at continental speeds two up with luggage, the oil temp goes up from 5 to 6 bars. Not a worry for me, but if it kept up at 7, I'd consider a bit less throttle for a while.
I travelled back up from the Dordogne last year fully loaded with SWIMBO on the back, I spend most of the time between 110-115 (Until hindered by traffic)
I kept that pace up all the way back where possible. Something in the region of 530 miles. No problems at all!

What you do not know is that the scale (like Spinal Tap's amps) actualy goes up to 11.... It stops at seven blocks only because BuMW ran out of space on the display...
You have zero chance of damaging anything all day every day at a steady 85/90 mph at 5/6k in 6th gear on a motorway, German or not.... Not that it's very likely you will be able to average 90 mph of course, due to traffic...
So it shows 11 just before the oil sight glass melts
Ye canna push the crystals that hard, Skipper....
Traffic and speed limits will be the speed-lmiting obstacles. You'd be lucky to run at 80mph for half an hour on most german autobahns.
My tip for fast autobahnstormingmitkeinkackinthepants is to use your mirrors regardless of how fast you're going.
I recall driving to frankfurt in a Z4 at a reasonable clip (200-220kph) and using my mirrors rarely (how likely is it that someone is coming up behind at that speed
). When i did glance in the mirror there was a Merc S Class about a metre from my bumper flashing his lights at me to move over

Maybe not on an 1100 but on an 1150:

It makes no difference what style the bike is (sport,tourer etc.) they all have engines with same moving internals, pistons, con-rods & crankshafts. All are happy\designed to run below the max rpm as long as there is fuel & oil until something breaks (100k+ miles
) . Generally:
lower revs = less wear = longer lasting engine.
Higher revs = more wear = shorter lasting engine.
Generally:
lower revs = less wear = longer lasting engine.
Higher revs = more wear = shorter lasting engine.
Time difference between 'shorter' and 'longer' periods of time? Nobody knows.
What's quite possible (indeed quite likely) however is that the vehicle will be written off before it gets to 100,000.

Crossing Germany on Autobahn
Crossed Germany on an R1100rt 2 years ago. 500 miles in 6 hours ( including 3 stops for food & fuel) Kept up an indicated 115 - 120 mph steady.
All that happened was the bike stopped using oil after this. I It had previously used a little oil)
Does that answer you?

I am amazed that Honda replaced anything, I have had their cars and bikes in the past and they always bitch about warranty claims, trying to squirm out of their obligations.

To Karlp : the R12GS engine has it's highest torque output at around 5500/5750 rpm, (<'08 / >'08) which means that's where it's strongest, and that's where the engine turns at it's best, where it's most comfortable. Should therefore be no problem riding between 5000 and 6000 rpm. The R12GS has it's max power output at around 7000/7500 rpm. Max engine speed is at around 8000, so it's useless going higher than that.
Note : I've written 'around X rpm' because dyno results always show a different figure compared with the official ones.
Wanting to find out what it's capable of, I've gone full out once on an empty unrestricted speed piece of Autobahn, for a distance of about 30km. The speedometer went to 220kph which is the R12GS's official max speed. Speedometers are always a bit 'optimistic', but the speed was impressive. When I got sudden drawbacks in power, then re-accelerations, etc, I realised the revlimiter was cutting in. Which, to be honest, didn't feel comfortable at that speed.
As far as long term effects of high speeding goes : I've read some stories of RH exhaust valve mishaps at high speeds, but unfortunately only BMW knows enough about the cause of RH exhaust valve failure to make conclusions.
On long stretches of highway, traffic permitting, 5 to 6000 rpm is where I ride.
