I believe you, they are really nice bearings.....

Myself I have never really had issues with bearings..... On the Taiwanese I have had to change some fronts early, but for the most part I don't really have any issues with any bearings...Which is really crazy when you consider how badly I treat some of my engines.....I doubt there are many people who who run as many different brands of engines as hard as I run them..And I never have bearing failures....From time to time I will change bearings if i feel some wear......Yet I see plenty of other people's engines barely out of breakin with shot bearings.......Myself I think keeping the engine clean, proper tune and a fuel with proper lubrication is the key to bearings.........If one of those 3 things is not in line your going to have bearing issues whether they are ceramic or steel........

edit... I have definitely bearings fail, just it is never with my own personal engines, and I do not treat my engine gently by any means......
