With the 2024 season that canm to an end a few weeks ago, the SBK Commission met to clarify and make some changes to the regulations for next year. What is concerning, among other things, is the limitation of fuel flow allowed in 2025, a year during which restrictions on tests and the number of tires used in each round will also come into effect.
Changes to sporting regulations
On the sporting regulations front for the SBK, a restriction on tests will be applied, in order to reduce development costs, and the number of tires used in each round will also be reduced.
The SBK commission also decided to toughen the current penalties for violating rules regarding flags and yellow lights to further protect track officials. From now on, riders will have to slow down sufficiently to ensure the safety of their colleagues and trackside personnel or risk incurring a harsher penalty than they are used to.
With the recent introduction of rules regarding the minimum age of riders who can take part in the FIM Supersport World Championship, some exceptions have been defined regarding the top three finishers in the FIM Supersport 300 World Championship, the top three in the FIME Moto2 European Championship, and the FIME Stock European Championship. These riders will be able to take part in the 2025 season of the SSP, even if they have not reached the minimum age, but they must be at least 17 years of age.
Instead, on the Women's World Championship front, the minimum time required to qualify will be set at 110% of the time of the fastest rider, and a race that starts in dry conditions could be interrupted should the weather conditions change and the track becomes wet.
Changes to technical regulations
Starting in 2025, a fuel flow restriction will be introduced in the SBK class to limit engine performance. The initial limit will be set for all manufacturers at 47 Kg/H, with a tolerance of 2 grams per lap above the 47 Kg/H limit. The limit for 2026 will be decided in late July 2025, after the first part of the season has been analyzed.
Regarding the attachment of fins and aerodynamic appendages, the regulations already in force in the MotoGP will also be applied to the SBK. Under normal operating conditions, the parts must not exceed a deflection of 10 mm at any point, with the application of a downward vertical load of 50 N, with a steel spherical penetrator having a 20 mm radius.
In the same category, new "virgin" frame parts can be freely marked, but they must contain the model code recorded in the bike's FIM Homologation, and the decision was made that the procedure for reading the new marking must be declared by each manufacturer to the FIM Technical Director before the start of the season.
The SBK commission is also continuing to work on the introduction of a new World SBK entry category in 2026, which will replace the World Supersport 300. Talks have begun regarding the choice of bikes and related homologations.
