Maybe I have old ones but the ones I do have fit flush with the bearing in the swingarm or linkage. I just received a replacement shoulder bolt (because one was getting mangled) and I noticed it's not as big. The outer edge of the bearing is exposed. I'm not too worried about it but have they changed recently??
