| Well as I said in my first post, I'm aware of the cathodic/galvanic whatever-you-want-to-call-it issue, but I've I've been putting stainless steel allen screws on my bikes since Triumph Bonneville primary chaincases in the Seventies, and can't say I've had too many problems with that.
Funny to see titanium mentioned. Titianium of course comes in various grades, but my understanding was that titanium bolts are around the same strength as stainless ones, and certainly not up to Grade 12.9 standards. If anyone has chapter and verse to show me different, I'd be interested to see.
Personally I can't say I've had any issues with ovalling of the recesses. of course, with stainless, as with titanium, there are better, and less good suppliers around.
I'm not at home to check the torque setting of the bolts in my manual (and does ducati.com even give this sort of info any more? It used to have torque settings and all sorts of useful data available when the 748/998 bikes were current), but as they're a tapping, rather than "nut and bolt", I'd be surprised if they're that high.
