Recent seasons:  At the height of the clubs expansion, after the '60s and '50s, the club had 22 different sports departments. Only two remain to this day, and the declining economy and lack of money during the Polish Second Republic, as with lots of other Polish clubs at the time, meant that over the years the departments were shut down one by one. However, the weightlifting and hockey sections have produced several international athletes, such as weightlifting world record holder Antoni Pietruszek, and hockey national team player Wiktor Olszowski. BKS fans usually focus on football team due to the culture around the sport, however, they do sometimes support the women's volleyball team too for important games. The fans are usually nicknamed "South Boys", and frequently highlight the fact they are the most southward major club in Poland. They have friendships with fans of Zagłębie Sosnowiec and Olimpia Elbląg, in the past they used to have a friendship with fans of Legia Warsaw. Their biggest rivals are fellow locals Podbeskidzie Bielsko-Biała with whom they contest the Bielsko-Biała Derby, however, they also have rivalries with most Upper Silesian teams.
