Unfortunately, it's all but impossible to narrow it down to a particular model Your only chance would be to contact Honda Japan, but I wouldn't hold out much hope.

There must have been many thousands of Rothman's SPs over the years! And common folklore even has it that dealers in Japan would 'convert' other SPs to Rothman's colours due to high demand.

If the frame number falls in the correct range, the relevant bits are SP, and the bodywork is original, then I would be happy with that.
