Hi JC, my friend, can you shared the specs of photos of mini cooper bearing that I can use in my FD of r1150gsa?

See the difference in the two bearings, above is the deep groove bearing that BMW installed and below is the Angular contact bearing I inserted.

If you do insert an Angular contact bearing, make sure you drill three little (3.2mm) holes like below in order to be able to use a 3mm pin punch to knock the outer ring of the Angular bearing out of the casing, as the bearing can easily come apart like a taper roller bearing and then you cant get the ring out. I used sylicone sealer to plug the little holes and has lasted the 50,000kms with no oil leaks.

Below is the package the Angular bearing came in with with all the relevant numbers you might need to order one.

So it worked for my GS, She has now done close to 180,000kms in total and I hope never to see my sump plug look like below again when I drain the oil of the dif. . . . . . I'm ready for the next 180,000kms!

Hope this helped a bit.

Just completed the bearing change in my 1100GS, 140k km. Found a slight wobble 12/6 o'clock so a preemptive strike to sort it out. Quite an easy job really, mined you my press helped a lot.
Wobble all gone no rumble and ready for the next big trip

Hi Johan
I've just joined today and found this thread wrt to the angular contact bearing. Did it work out for you and can you please send me the part numbers for the bearings and seal required for a 2004 R1150Gs.

Have a look at this website - they may have the answer via an online BMW parts microfiche:


I know that it looks like it is for an F650GS but that is just the entry title and you can select the year and model of your choice on the website
