I'm pretty sure the only way to check if you have an SP or an early Roche replica is to look at the injectors,all SPs had twin injectors per body. Strada's and the American SPO had one injector per body. the SP2/3 came with alloy tanks,SP3 with carbon fibre and the SP4/5 with steel tanks. also the SP2 came with low level pipes,the SPS had carbon fairing and the radiator fan removed to save weight. is yours an early white frame and wheels model? hope this helps ian
The question comes from reading the ook I just bought called something like 851/888 performance review that said the stradas redlined at 9k and sp at 10k so it looks like I have a later rev counter. Then again these journo types are very unreliable.
NP The SPO was for the Americans only it is baicaly a Strada engine with a single seat and hi-level pipes there was one on Ebay that went for £7,500 i expect the buyer thought he was getting a type of SP. I take it your refering to the book titled Ducati 851/888 performance portfolio by Brooklands books? ian
