"After some research, these are my findings so far
BMW R1200 R / GS / RS / Adventure share the same alternator/stator. The stator dimensions are 133mm OD, 60mm ID, and 13mm core thickness. It has 21 coils
Part numbers:
12 31 8 526 908 - available till 03.04.2014
12 31 7 724 032 - available till 23.11.2016
12 31 8 356 824 - the current part
R1200RT has different alternator, heavier flywheel, stator with 139mm OD, other dimensions are not known to me at the moment. It has 15 coils.
Part numbers:
12 31 8 541 003 - available till 16.02.2015
12 31 8 556 028 - the current part
