It seems the 2012 Norge was changed over to roller lifters some time later in 2012. Reading through the postings I see it seems nobody really knows exactly when so I am offering up to start the guessing. My serial number is ZGULPT006CM111849 and I still had flat lifters. Anybody with a later number know which their bike came with? If you bought it used it may have been converted before you purchased it. This may help somebody about to buy a 2012 Norge.
If you want more info mine and others dealings on this are in the Stelvio postings under Rollerization.
