Starting from the 2026 season, a concession system will be introduced to the ST1000 class to reduce performance gaps between manufacturers, as well as to increase the number of entrants per race. The system allows approved low-cost concession parts designed to help manufacturers with a performance disadvantage reach a fair competitive baseline. Throughout the season, performance will be reviewed to determine whether a manufacturer should retain or have adjustments made to its concessions.
The championship will also drop the system of assigning race numbers based on last season's standings, and riders will instead use their own chosen personal numbers. This will apply to all four classes and only to full-season entrants.
