According to my Haynes manual, the 748s was the replacement for the 748SPS. I have a 2001 model 748s and am not 100% convinced this is a replacement model (yes it does have nitride forks, marchesinis).
I am only asking because I am curious to know the stock BHP figures for one. Does anyone have a definitive answer?
Log book says 'Biposto' but it has a single seat with 748s on it ? Mine too has the nitride forks and the Brembo Marchensini's. I'm intrigued as you are...
They're all homologation bikes for racing and have higher spec components, different suspension, cams etc to conform with supersport homologation rules
S replaces both Biposto and Strada which were the base bikes but with different seat types. The S became available as either a bip or mono. Leaving the E as the entry level bike.
