Hey hey. I'm looking for the actual bearing numbers not Ducati part numbers. My bike is a hyper 821(same as the monster 821 as well as a few other 4 valve motors)but that group is less active than this one and I got no answers. Can anyone help me out with this please. I want to source new bearings before I take the bike out of service for the maintenance as it is my daily driver. I see there is a few places that have lists of bearing numbers for the 2 valve motors, is there a list for the 4 valve motors?
