R 51/2 front fork

[Chen Kalmanovich]

Does the R 51/2 fork fit the R 51/3 1951 and also to the R 67/2 1952?
If not, what is the difference among them?

[kassie]

Yes, as far is know the early R51/3 and even R67/2 fork will fit. They are even very much the same as the prewar R51, R61 and R71 forks.
