[QUOTE="Bob Scott"] Allegedly. In some cases. They were a small factory & I've a sneaking suspicion that the bikes were specced on the "whatever Luigi has handy" technique.[/QUOTE] Ducati were much the same, in that era. [QUOTE] IIRC the Corsas got floating discs (maybe all round, maybe front only), goldline brembo calipers, high comp pistons, bumpy cams & larger valves. The engines should have CR stamped into the heads somewhere or other - but offhand I can't remember where. The SFC1000s were supposed to have the same spec engine as the Corsa, 300mm floating discs at the front, Brembo P08 Goldline calipers & M1R forks. I've seen SFCs with P09 calipers & floating discs all round. It doesn't half make life interesting when Carole Gnash[/QUOTE] Carole Gnash. I like that. :-)) [QUOTE] ask if you're bike is standard & you tell them you think so - AFAIK the SFCs came with 2 different types of caliper, 2 different types of clock (Veglia or smiths), 3 different exhausts, 2 styles of wheel - I mean they only made 500 or so of the damn things so how did they manage this much random variety?[/QUOTE] Luigi, like you said.
