HELP !..........Wheel bearing type

[Guest]

Need some help from the brain trust out there !
I have a late 79’ GS750…with factory mag wheels
I received the bike in boxes and most parts, I have to get some new wheel bearings, and I see that there are different bearings for “EC”, and “EN”, how dose one determine what one needs ??
Thank you for any help

Might be they changed to different seals on the bearings. 63032RS abd 63022RS I think, but check here:

Could well be the shield type. Istr, the first wheel bearings I bought for my '79, I had a choice of metal shield or more of a proper seal built in. The originals I took out were metal shielded and I wasn't too impressed with the life span of them, to be honest. I went with Koyo, then and since, and never had the slightest doubt about the efficacy of the rubber seal, the Koyo bearings lasting much, much longer - probably related to the seal, as well as quality of manufacture.
