Career
Sjösten won the world pairs championship in 1974 with Anders Michanek and became world team champion three times representing Sweden, in 1962, 1964 and 1970.

Sjösten rode for Masarna, Vargarna and Bysarna in the Swedish leagues and for Belle Vue Aces, Wolverhampton Wolves and Bristol Bulldogs in the British League. An excellent starter, he was renowned for having a 'wild' style of riding with the rear of the bike sliding further out on the bends than is usual and was often considered rough on his opponents.
He retired after his brother Christer was killed in a meeting in Brisbane, Australia in 1979.
