1980 Fork Leg

Post by EMS »

I have a couple of lower fork legs and don't know from which year they are. :? I know they are for 35mm tubes but they seem to measure 57mm on the upper end where the fork stabilizer would clamp. My 79 forks only measure 56mm there. I faintly remember that Honda changed something when they put air into the 1980 forks. Could someone with a stock 1980 fork please confirm this for me? What do they measure on the outside at the large diameter where the fork seals sit, where the leg has the grooves :?:

My '80 is 56mm up by the fork seal.

Mike:
I think you'll find the upper leg (just below the seal) machined for a bushing, that the '79 didn't have. At least that's what the parts book shows and what I remember from rebuilding them.

I found this in my own records:

The front fork was air assist and the steering neck incorporated tapered roller bearings which were 2mm further apart. Each fork leg had two anti-stiction rings instead of one. The fork sliders were 1mm larger, 45 up from previously 44mm. Stanchions remained at 35mm.
