Double Bearing swing arm?

[mike96]

Been doing some research be I don't seem to see anyone who has done it yet... I was wondering if anyone has ever double bearing-ed their swing arm, replace the bushing on the inside pivot points with another set of bearings? Any benefits? Worth the pain or not?

I've got 4 needle bearings in my swingarm. It came that way so when I replaced them I kept it with 4 bearings. Not sure on the benefit but I don't think having 2 extra bearings is a bad thing? Putting the new ones in wasn't hard either. I put the bearings in the freezer and then tapped them in with a socket
