Apart from the cc so bigger Pistons in the 1198 does anyone know what other differences there are between the 2 engines? I've heard the 1198 has lighter and stronger cases.
Some info re engine difference (1098-1198): Ducati 1198 and 1198S review - Page 3 - Road Tests: First Rides - Visordown
The 1198 uses Vacuum Die Cast Cases same as the 848. Stronger ? Maybe but not a lot in it I would think. The crank is different maybe because the 1198 uses different rods, don't know for certain. The shell bearing design is much the same I think, there is no traditional Big end bearing as such. The main bearings were updated mid 1098 production I believe to the same as the 1198 used. Speak to someone like Chris or Richard at Louigi Moto. I'm sure they have will have played with all sorts of part combinations at some point.
