I am 60 years old and still bang my 30+ year old 454 to that 10 grand redline at times. All in the lower gears though as I have no need to go 100 mph any more. I think 80 is about as fast as I have had it.
Every bike I ever had I redlined and never dropped a valve or grenaded an engine.
It has 27k on her, I think. Been awhile since I checked but I keep her maintained pretty well.
