Sorta depends on how religious you are, or how good a physicist. Those two groups have converging views of the nature of reality. Suffice it say that once you are convinced of something it changes the reality you live in. You will find what you expect to find. I'm a pretty hard core empiricist but I've become convinced. Perhaps I wanted to be. Ouroboros.
Why on earth would I buy them again?
I'll mail some to you if you'd like to try them?
If you're able to handle the heat here, you'll find much information based on individuals personal experiences with their motorcycles.
Burritos to you too.
The way you wrench may have you going through them?
You are too kind, I'd take you up on it but it'd be costly. You should buy gas instead.
I seldom doubt anyone's experience, as they describe it. What they make of it? Well, I take most things under advisement...
Doing some investigations on the 16007 C3, another bearing we buy from time to time, lead to some interesting tidbits (aside from the fact that the dealer price is good, if they are the real deal). This from SKF:
"The complete bearing designation, i.e. the basic designation with supplementary designations is always marked on the bearing package, whereas the designation marked on the bearing may sometimes be incomplete, e.g. for manufacturing reasons."

I have a very old FAG 30203A here. Made in Portugal.
Search on SKF site for 30203A yields only 30203J2
17 x 40 13.25

The A suffix indicates "modified internal construction"
I can bring either up on CAD if I cared much more and look for variations or notes on the drawings.
----------------------------------------
Both sites list the J suffix as denoting a stamped steel cage. This holds for many other types of bearings other than the ball and tapered rollers I was specifically looking at--it is in the designation tables. These guys are following ISO and DIN standards so I expect some consistency. I have to pay $$ to get my hands on the standards themselves so....
--------------------------------------
Conclusion: your bearing don't fit, as you observe, but it ain't the J that did it. if they came in boxes, examine the designation on those. When some one asks you where you got them, answer. This may or may not be relevant.
Looking for the 16007 C3 I found them for $11 at Bearings-direct.com, $20 at MAX BMW , $26 on Amazon from Amazon, and $35 at Motion industries. I didn't look at Grainger or MSC.
