Very timely questions. I'm getting ready to re-fill my forks on my R100GS. According to my receipts the last time it was done they put in 7.5 weight BMW brand fork oil - done at a dealer in Denver. I went and bought some in Vancouver - one dealer uses Belray products and the other used Motul - these are both BMW organizations and according to Steve G they have common ownership. It just seems that they are pushing different product lines. As per the MAX BMW fiche, I am putting in 10W.

I was careful in draining each leg and measured what came out. The left leg contained 360 ml - it should have had 410 ml. The right leg had 370 ml - it should have had 440 ml. There are no leaks on my fork legs. I will be putting in pre-measured quantities of 410/440 mls as per the manual. It should be fine...
