The final design for this part came in 1956 and it has lasted all through 1984 and probably beyond.


The Iron Sportster mainshaft is a triumph of engineering. The general design has sustained from 1952 to 1984. There were teething problems in the early K-model, but they were all cured by 1957 with the introduction of the Sportster.
