Seen them sell bikes before. Personally I wouldn't buy a bike that has barely if ever been ran in the past 6-7 years. Too much of a chance for seals etc to dry out, but if you are mechanically adept it could be a bargain.
They've obviously been moving bits to make the most of the money tied up in this as the seat cowl, hugger and under tray in the original advert were in Winning red not black! Spoiled it IMO. http://www.hondacbr1000.co.uk/default.aspx
