We are looking at some small updates moving into 2025.
In the Streetstock class there will be a relaxing of the engine modifications to Honda, KTM , Aprilia and Yamaha with use of modified cam shafts with high compression pistons.
Bikes must remain 125cc.
The Suzuki will still remain as they were this year with a standard engine but open electronics. This is to allow greater choice of bike and keep the overall cost down with more donor bikes more readily available with a wider range of competitive manufacturers.
Production and Moto4 rules will remain unchanged
Please note that some circuits next year have noise control monitoring done by the council.
This means the Airbox rule and a well maintained homologated silencer are critical for the individual team and series compliance of these noise restrictions.
