Beatty cam tools?

This question has probably been asked before, why is it necessary, or at least desirable, to change out the inner cam bearing with a cam change. Especially if the bike is low milage to start with. Are the stock inner bearings prone to failure? If so you would think you would read here of a lot of them failing on bikes left stock. Just got my 255 cams in and want to know why I'm doing something in the install, not just because everyone says do it.

I bought the Beatty tool since I am a tool junkie anyway; but would have been comfortable with the AZ puller if I needed to save a few $$. Can't answer your question about failures but I was going to be in there anyway so seeing the difference $20.00 +/- for bearings was a no-brainer for me. JMHO

Just wondering as the Limited has less than 10K on it and it would seem if the stock bearings were that prone to failure you would hear a lot more about it. Lot of riders on here giving high milages on 07s and newer and I don't recall reading the first time of an inner cam bearing failer. May be something going on like a much higher load being put on the inner bearing with non stock cams. If so, that is what I'm trying find information on, not just change them because everyone is paranoid about them.

I'm probably going to replace them, I'm just trying to find out if people are replacing them because there is a history of them failing when non stock cams are installed or just because everyone is paranoid they will fail. I notice in the SE catalog the 110 kit, even though it lists 255 cams, doesn't list SE inner cam bearings or recommend they be installed. Might be in the kit instructions and not in the catalog. I've seen the photos of what happens if anything it turned loose to wander around in these engines, so a little paranoia probably is a healthy thing.
