Hey man! if you havent found the proper size bearing yet, go to this site and get the service manual for your R. I think the size of the bearing should be in it. Try this link:

if its not in the manual, try www.bikebandit.com and they may be there under OEM parts.
hope this helps!

Looking to get some hot rod bearings for my engine build. They don't show any for the 82. Need the size so they can check for me.

They are the same from 81-84.

we only use Honda bearings and seals. Did you check to see if bikebandit listed the bearing size? I have an air cooled crank and an 85 liquid cooled crank sitting in front of me as we speak. I measured them with a vernier caliper and they are the same on the crank diameter but I don't have a case apart to measure the case diameter. The crank diameter is 28mm on both.

They're the same as the 85.
