BMW and Ducati have both been affected by the latest changes to the maximum fuel flow limits in WorldSBK.
WorldSBK has announced fuel flow limit changes for BMW and Ducati for the second time in 2025 before the Czech Round, following reaching the second Concession Checkpoint in the season, resulting in a 0.5kg/h reduction for both manufacturers.
BMW’s reduction is due to its performance meeting the threshold for a Step 1 reduction, whereas Ducati received the same reduction for accumulating over 12 Concession Points more than the next manufacturer.
Both BMW and Ducati now have a total reduction of 1kg/h of maximum fuel flow compared to the season’s initial 47kg/h limit, established during the Dutch Round at Assen.
After every second round, which is the Concession Checkpoint, the fuel flow limits can be adjusted, with the next potential adjustment scheduled for the sixth round of the season in Misano on June 13–15.
Variable fuel flow limits were introduced as a new performance balancing mechanism in the 2025 World Superbike season, replacing the previous RPM-based system.
