After The Winter War and The Continuation War, the city of Viipuri was ceded to Soviet Union and Reipas was forced to move within Finnish borders. In 1945 Reipas relocated to Lahti where it continued, in the new home town of the evacuees, under its original name until renamed to Lahden Reipas. In 1975, Kiekkoreipas was formed to take over hockey operations from Lahden Reipas.
