Short answer - No.
I asked a similar question a few months back... the red-line on an 1100 is like what.. 8k? If you are sitting at red-line for long periods of time yes, you can damage your bike. The thing is you will never really hit max rpms... I mean you *could* but I can get to 85-90mph in 5th gear hitting 3500-4000 rpms.
If you have the clutch pulled in and are just revving, you can ding 8k rpms easily however.
A tachometer will help you visualize what's going on and give you some good visual feedback. They are quite easy to install and fairly cheap.
