From JamesList, a site I picked up via the good old boys at the PB forum.
"For Sale: 1987 RC30 - Ghost. One of the rarest bikes in the world, only 30 white RC30 bikes were ever built specifically for the 1987 Suzuka 8 hour race. This completely original bike was owned by a Honda employee and garaged minutes from the Suzuka circuit. Included with the sale is a certificate of authenticity from the Honda Motor Corporation confirming this to be one of the worlds rarest collectibles. 19,000 kms fully documented."
