How much life do you think this lower bearing had left? Believe it or not, it came out of an 04 ST3 leftover I recently purchased (794 miles). I only discovered the problem as a result of my swapping out the front forks and upper triple with ST4s versions. Anybody know what size socket I can use to press a new race into the lower stem? Needless to say, the bearing did a nice job on the plating on the one that's currently in there.
