I read/re-read jon thompson's book yesterday and although he doesn't say so precisely, the implications is there that 900ss was bordi's work
i spent time in the ferracci shop in 1990-91 when the 851 development was going on...i'm betting that he could comment on this...i've been told that the SuperLight was Eraldo's idea (to be called the superlegga)...he must have some knowledge of the 900sss birthing...i'll ask next time i'm in willow grove
i know of course about tamburini's efforts at cagiva/ducati/mv but have often wondered if in those bimota years, he was trading design work for engines for the KB's,SB's etc
