As my less than a year old Griso was down waiting on replacement deer hunting parts, I took the opportunity to pull the swing arm and can report there was no lubrication (grease) more than what oil is normally present in a new bearing package. The shock linkage barely had any either.
It really is something that needs to be done to all of the bikes. Note, of my 2008 1200 Sport, 2013 Stelvio, and above mentioned 2016 Griso, only the Stelvio had any trace of grease added at assembly, and it was just a small smear not nearly enough worked in, IMHO.
