Ducati lightweight aluminum/ergal flywheel for 2V supersports -- these would be the 98+ models -- although with Ducati, a few 97s got the newer ignition system. Best way to tell is that there are 3 yellow wires exiting the stator cover, not 2. As new. Purchased out of the UK, but sold by Ducati-Kaemna in Germany. Here is the link: https://www.ducati-kaemna.com/schwungrad-ergal-900-ab-98... Price is in US funds -- I'm in Canada, so there will be additional shipping, but not much. This will work on a 900, 750, and 600. I purchased it for a potential track project, but its gonna stay on the street, so this would be overkill. These aren't the cheap SSP ones that have been know to fail -- Kaemna use these on their successful twins racers in Europe. We can work out GBP or Euro equivalent if you are interested.
