In Sweden, the Bauhausligan will implement changes to team averages, roster flexibility, and playoff structures. Key updates include increasing the maximum team average to 10.750, expanding the number of transfer cards, and transitioning semifinals to a home-and-away aggregate format. New squad composition requirements aim to support young talent by mandating specific numbers of U21 and Svemo-licensed riders. Similarly, the Danish SpeedwayLigaen is introducing reforms to elevate its international standing. These changes include expanding team rosters to include an additional senior rider and dedicated spots for two junior riders, with at least one being Danish. The league will also increase the number of heats per meeting from 14 to 15 and reinstate a ‘guest’ system for U21 riders with averages below 0.800. ## Timeline ### 2026-10-22: Denmark Speedway League announces major rule changes for 2027 The Danish speedway federation is introducing major rule changes for the 2027 SpeedwayLigaen season, including expanded rosters, mandatory junior spots, and the return of the ‘guest’ rider system. 2 sources. https://clstr.news/cluster/denmark-speedway-league-announces-major-rule-changes-for-2027 ### 2026-10-06: Bauhausligan announces new speedway regulations for 2027 season Svensk Elitspeedway has announced new rules for the 2027 Bauhausligan, including updated team averages, expanded roster flexibility, and a new home-and-away format for the semifinals. 2 sources. https://clstr.news/cluster/bauhausligan-announces-new-speedway-regulations-for-2027-season --- Cite as: European speedway league regulatory changes.
