Two weeks ago on my way home I noticed increasing vibrations at speeds over 70mph.
Initially I figured the bearings were finally on the way out - a week before when mounting new tires I noticed some rough spots in the bearings - but when I put the bike on the center stand and turned the wheel I heard clonk-clonk noises coming from near the engine.
So I got a used drive-shaft from the dutch version of Craigs-list and pulled the swingarm.
Not sure if you can see but in the photo below you're looking at what's left of a bearing. The outside of the casing had completely broken off, on the other side there was a big crack running along the bearing.
While I was at it, I also replaced the rear disk and wheel bearings this weekend
