Picked up new steering head bearings + races for my R90/6 at the local dealer and it t seems that the original part was superceded by p/n 31 42 7 663 941 which is currently used on the G650 bikes.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.
