Well, sir, you are in the right place to get to the bottom of all things V11 !
And you are correct that the potentially fragile [aluminium] flywheel, used only with the single plate clutch, is found only in the 2001 Rosso Mandello, and 2002 Scura and Tenni. All other V11 1999-2005 (let us know if you find a verified 2006!) have twin plate clutches over a steel (bombproof) flywheel.
There is still no final consensus if the aluminum flywheel failures are only from a batch/production run, or whether the problem may not have affected 2001 models (Rosso Mandello). a work in progress!
Looking forward to your introduction and hearing your V11 experiences. Welcome, @Icenian!
