I personally always use water resistant grease; it's well worth the few quid extra. Fuchs Renolit Aqua 2 is my preferred choice.

If you're going to grease the swingarm pivot and linkage then it is well worth removing the solid MPL lubricant from those bearings that have it (swingarm and one of the three in the linkage). MPL is designed to bleed oils onto the needles through use, but the problem is eventually it gives up all the oil is carries rendering it useless. It looks like a cage but isn't; they are full complement bearings so no cage is needed. Also, if you don't remove it then you can't get any normal grease in!

I've done mine twice, the first time removing the MPL. Second time apart the whole setup was in perfect nick. No wear and everything still well greased.

Ohlins did a good "walk-through" guide in four parts...
