WorldSBK makes changes to fuel flow performance balancing regulations

A regulation update has been made by WorldSBK, with a change to the fuel flow regulations ahead of this weekend’s Emilia-Romagna Round of the 2025 season at Misano.

Previously, the fuel flow performance balancing worked on a step-based system with three different steps. The first step of performance reduction meant a 0.5kg/h fuel flow reduction, the second meant 1.0kg/h, and step three meant 1.5kg/h.

The adjustments were to be made after each concessions checkpoint, meaning after every second round in the season. After each of the first two checkpoints, Ducati and BMW were both given 0.5kg/h reductions, meaning at the Czech Round they both raced with 1.0kg/h less maximum fuel flow than the rest of the field.

The system was criticised by BMW’s Toprak Razgatlioglu, the reigning World Superbike Champion, who felt that it was incorrect that BMW was receiving the same reduction as Ducati after each checkpoint.

The update to the system will make the key change that penalties will now be applied linearly, rather than in the previous step-based system.

“For WorldSBK Class, the step-based system of performance calculation is replaced by a linear penalty system, effective from Checkpoint 3,” the Decision of the Superbike Commission reads.

“Only permanent riders are included in performance assessments, with wildcard and replacement riders excluded. Manufacturers must complete at least 50 laps across two events to be eligible for fuel flow concessions or penalties.

“A balanced performance range means no action is taken, while underperformance triggers a proportional penalty.

“There is no buffer period – penalties remain until performance improves.

“Recovery is only possible through meeting positive performance thresholds, with limited gains allowed per checkpoint.”
