Default OK so how fast

I am planning a trip out west Wyoming, Montana etc.
Anyway is there any problem with running my 2012 SG at sustained speeds of 85 to 90 mph in 6th gear.
I know the bike redlines at 5500 rpm and at these speeds I won't be anywhere near that but is running at 3500 to 4000 rpm for sustained periods an issue with these engines beings they are air cooled?
I have traveled in these states before so I know that these kinds of sustained speeds are realistic. So what do you all think, will my engine/bike be OK running at these speeds/RPM's?

It will be fine. You'll get crappy gas mileage, but it will be fine.

You can tell the state trooper you were just testing out your engine to see how it holds up at 90 mph for extended periods of time...there's a small chance he hasn't heard that one before.

As long as you have plenty of cash for speeding tickets you'll be good to go :P

I agree it won't be a problem at all. Not sure but I think it was 07 when they finally came out with the sixth gear......correct me if I'm wrong. One thing though, seems like 3500-4000 seems like high rpm's for that speed. Again though, I agree with the previous poster, you could ride that speed on a 5 speed, been done for years.

Yeah 4000 rpm is a bit high for 95 mph, but hey I never said I wouldn't ride over 100.

Actually 78.3 mph at 3000 rpm.
But you are correct about the purring.
