In a thrilling twist of events at this weekend’s World Superbike Round in Assen, Ducati and BMW are confronting new challenges as they adapt to freshly adjusted fuel flow limits. These changes, stemming from the first ‘Concession Checkpoint’ of the 2025 season, mark a pivotal moment in the competitive landscape of superbike racing. Concession Checkpoint Insights The latest checkpoint, occurring after the opening two rounds at Phillip Island and Portimao, has introduced significant fuel flow alterations for Ducati and BMW.
According to a statement from the FIM, both manufacturers were found to have exceeded the performance value thresholds defined by the World Superbike Regulations. These thresholds are crucial as they ensure that no single manufacturer gains an overwhelming advantage, thus maintaining the championship’s competitive spirit.

5 kg/h, under the ‘Step 1 Fuel Flow reduction.’ As stated in the FIM WorldSBK Regulations, this measure is intended to rein in manufacturers whose performance edges towards overdominance. This strategic move ensures a level playing field and is expected to shape the dynamics in upcoming races.
Ducati’s Dominance at Season Opener At the season opener in Phillip Island, Ducati showcased exceptional dominance. With four of their riders landing on the podium and Nicolo Bulega clinching victories across all three races, the Italian powerhouse made an indelible mark. This impressive performance undoubtedly influenced the decision to alter fuel flow limits, challenging Ducati to maintain their edge under new constraints.
BMW’s Command at Portimao Similarly, BMW’s resounding success at the next round in Portimao with Toprak Razgatlioglu at the helm, further highlighted the need for regulation adjustments. Razgatlioglu’s M1000RR triumphs, with a consistent presence on the podium alongside rival Ducati riders, underscored a strategic necessity for the FIM’s intervention to balance competitive fairness. A Balanced Championship Ahead As indicated by the FIM, the new fuel flow regulations are designed to ensure a balanced and competitive championship.
These adjustments, though challenging for Ducati and BMW, offer an exciting opportunity for emergent narratives and unexpected twists as the season unfolds.
