That new ceramic disc may actually be for 49063-1055 mechanical seal for other models.
I measure the -1055 ceramic at 13.919mm ID & the metal body at 28.778mm OD. I believe that you may have Mis-Packaged Parts.
I measure the KLR 49063-1056 metal body at 24.231mm OD and the ceramic disc at 11.938mm ID, nearly the same as your old one.
Modify at "YOUR OWN RISK"!
Still riding my 1987 KL650-A1. 85,000+ miles & counting
