WorldSBK to Reduce Development Cost, Among Other Key Changes in 2025
WorldSBK officials confirm several regulation changes with a focus on reducing costs
Testing time for teams and riders in 2025 will be reduced in a bid to save on development costs, but there are plenty of other changes coming in 2025.
One of those surrounds fuel flow as the WorldSBK championship will now feature a fuel flow limitation that’s been introduced to limit the performance of the engines. From 2025, the starting fuel flow limit for all manufacturers starts at 47kg. A tolerance of 2 grams per lap beyond the 47kg limit has been allowed. For 2026, the limit will be reviewed before a decision is taken at the end of July 2025 after analysis during the first part of the season.
Like testing time, there will also be a restriction on aerodynamics, which comes after the same has happened in MotoGP.
A statement from WorldSBK officials said: “The rules applied in MotoGP regarding the attachment of winglets/aerodynamic appendices will be applied: under normal operating conditions, the attachment must have a maximum deflection of 10mm at any point when a vertical load of 50 N (normal force) is applied downwards with a 20mm radius spherical steel indenter.”
A limit, although what that number is has yet to be confirmed, has been introduced in regards to how many tyres can be used over the course of a single event. A new class will be introduced in 2026 but it will not expand the WorldSBK bill to four different categories. Instead, it is set to replace the current World Supersport 300 series.
As is the case in any professional, FIM-regulated series, wearing a fully functioning airbag has been a must for many years, but going forward regulations on this have become even stricter as only ‘type one or two’ (the highest level of safety and performance) variants can be used by riders.
