In my current career as a millwright, I have found that bearings that don't spin (in other words bearings that operate through less than 360 degree rotation) fail early. I have my own theories as to why this is, but I see it often. Yes, this is an oversimplification, but this is my empirical observation. I grease these more often than bearings that rotate. Swingarm bearings and headstock bearings kind of match that description for me.

Wonder what year it was? 2012 seems to be the problem year.
Not sure about Australia, but that color was only available in the US market in more recent years - 2015 to 2017 I believe.
