@Magwych Hopefully to Illustrate my thoughts in a clearer fashion
I would have expected to see the lines of the top of the gear rather than the back end of a gear
View attachment 546212
I still have a 1200ADV box with a snapped input shaft Which I always meant to fix
My 2004 1200 GS has an awfully high first gear Which was always a pain when Trying to pull away from steep junctions 2 up etc etc

Does that illustrate things better??
