2011 1200RT. 20k miles. The bearing between the swing arm and the final drive unit ...in particular the final drive unit bearing on the left ( tire) side continues to collect dirt around the circumference of the bearing/seal. After a few thousand miles I get the dark/dirt covering the pivot pin/isa screw etc.

I clean it off and it appears again. Everything around it stays clean.

I this a possible seal or bearing (17x 40x 13.25) leak and are both under warranty? All is good on the right side pivot pin.
