That changed 35 years ago on the occasion of the R-7A clearance tests, in anticipation of the arrival of 75' cars. However you are correct. As designed, both the BMT and IND specified 125 as the minimum radii for curves on their systems.

P.S. I think the absolute minimum would be 90 degrees as 89 would be a *decreasing* radius and therefore nonfeasible...
