Piraterna made their league debut during the 1949 Swedish speedway season, finishing 8th in a ten team division.[5] The following season in 1950, the club won their first honours in the newly created division 2.[6] However after 1951, the club would not ride in the league system for 20 years.
1971 to 1999
In 1971 the team returned to league action competing in division 3,[7] and two years later in 1973 gained promotion to division 2.[8] The club continued to race and despite a division 2 win in 1980 they never competed in the top division, which became the Elitserien in 1982.[9] The team then dropped out of the league in 1997 before returning in 1998 and winning division 2 in 1999.[10]
