Re: More beta RS blather..

Eric,

My RS number ends in R0310080, which I thought meant that it is the 80th
unit built (or perhaps the 10,080th one).  I also thought the numbers 31
were in each serial number for the '94's, meaning yours was the 977th built.
The tag also says, 3/93.  I did not think to write Bob's number down, but
the last seven digits were very different (no 3 or 31 in his, a 28 I seem to
remember - perhaps a much earlier bike)...still with 3/93 date.  Could BMW
have built 10K RS's in one month? It's not particularly important, but I'm
curious at what number they started the RS run.  It would give us an idea
how many of these early bikes are around.
