Wouldn't try it with any lesser engines.
Any modern engine will run pretty close to all day long at near redline. Most, if not all, have limiters that kick in before any damage is done.
Of two current bikes:
R1200, I can't see running up against the redline because it just isn't necessary (although I have hit the limiter a time or two)
TW200, I run that little sucker flat out ALL the time with no ill effects.
