Objectively, $500 for a Japanese bike from 1990 in "good used" condition with 105 and lesser components is ridiculous. You could find equal or better bikes with a half-dozen other brand names for half that or less. BUT the RB-1 has a cult following that inflates prices well beyond what can be objectively justified. Here (attached) is a list of recently completed RB-1 auctions on ebay.
Draw your own conclusions, but I think unworthy1 has nailed it.
