    BMW Bearing Grease

    Picked up new steering head bearings + races for my R90/6 at the local dealer and it t seems that the original part was superceded by p/n 31 42 7 663 941 which is currently used on the G650 bikes. As far as I can tell from looking at them, the only difference is the $$$.

    Something else I noticed is that they're packed with a yellow, waxy looking grease. I've only ever used red bearing grease of a completely different consistency and asked whether this was just on the bearings to prevent corrosion while they are in storage. The guy at the counter said BMW bearings come pre-packed from the factory now and they're ready for use.

    Anyone else experienced this? I could clean and repack, but obviously wouldn't bother if it's not necessary.

    Personally, I'd want to know what the grease was, so if there's any doubt, there will be doubt. Probably best to clean up and use what you're comfortable with. Peace of mind!

    After some searching it looks like BMW is using Shell Retinax EP2, though I can't seem to find any US stores that carry it. It's probably fine, but when I pack bearings they look like a greasy mess, maybe I'm just not used to seeing bearings packed with German efficiency (or Japanese since that's where the bearings are made)

    Considering what those bearings do, I would think an good quality, brand name bearing or lubricating grease would do.

    How will you get the races out and the bearing off the stem?
