It seems like the start could be a "yF" for end of '89 build. But after that, it's a 57cm not a 60, so any meaning is off.
Even stranger, why would Bridgestone use a non-standard numbering system? Could they have been contracting them?
Agreed, the 1st two characters are reverse format of what I would expect on a Bridgestone manufactured product. Unfortunately, I don't have any S/N data for other aluminum frames, so I can't offer an explanation for this. However, to the best of my knowledge, Bridgestone never incorporated size codes into the serial number. Certainly none of the Bridgestone S/N I've collected indicate this, though there is the odd case where coincidence could make the 3rd and 4th characters appear to be a size code.
