This is definitely not true, sorry.
Did you know that you can run into the rev limiter all day on a turbo bike without hurting anything? Setting it up properly is the key. Most turbo bikes make peak horsepower before 11,000 rpm anyway (there are exceptions), and there is no benefit to running into the limiter in the first place, but if you do accidentally get there, you won't have issues if your bike was set up correctly in the first place. That is why you let an experienced shop build your dream bike - so it doesn't turn into a nightmare.
The bad experience you had with your bike is not the norm!
