The end where the reservoir is, only has the bush, the other end has the needle bearing.
On the R1 the shock is mounted with the reservoir upwards I believe.
The angular movement at the upper end where it bolts to the frame is small, hence the simple bush at the reservoir end.
The bottom end, bolted to the swing arm linkage moves through greater angles hence the needle bearing. On the direct acting Versys it will move through bigger angles.
NOW! We are mounting it upside down so we have the bearings in the wrong position according to the way they were designed.
Maybe we should think about this guys!
This is just my theory I must add, I haven't had confirmation from anywhere.
The lower end with the bush can be fitted with a 10mm bolt without drilling the bush, by making spacers. The hardened bush for the needle rollers cannot, because there is a tapped 12mm hole in the frame, UNLESS we work out a way to use a 10mm bolt on that end also, by modifying the tapped hole arrangement to 10mm. I will check in the morning if there is room to get a nut behind the frame.
