It is probably shot. If there still is loose feeling after nstalling new bearing, the next maintenance is fork and especially fork bushings. Did both after 20 k kms and it is like new now. And rear shock maintenance since nitrogen charge will leak out. :D

Rusted solid probably.
Mine was fine when I looked at it. I think liberal use of power washers is what does for them.

At least yours had grease on them. Mine were pretty much bone dry and orange. I didn't use a pressure washer either.

F ' ' k dude!
Thank's for posting pictures of the head bearing.
Right now I'm glad that I've ordered new head bearings to be replaced during the dark and cold winter evenings in the garage... :)

Damn...that don't look healthy. Thanks for the pics, I'll have to check on mine this winter too... I'll probably just order a new set and replace them anyhow. 70k km on them now.
