The FIM is pleased to announce that electric bikes are allowed to line up against traditional combustion bikes in the 2025 FIM World Supercross Championship (WSX) and publishes the relevant sporting and technical regulations.
To compete in the FIM World Supercross Championship (SX1 and SX2 classes), the relevant electric motorcycles must meet the FIM’s Equivalence of Technologies / Balance of Performance (EOT/BOP) rules. These are a set of technical regulations designed by the FIM to ensure fair and safe competition between electric and internal combustion motorcycles. The motorcycles must also comply with FIM electric safety regulations, which include the use of approved ballast if necessary to meet the weight limit, plus compulsory functioning LED side lights (this requirement is only applicable during FIM World Supercross Championship events).

FIM President Jorge Viegas said: “Innovation and development have long been a key part of motorcycle sport, as such the FIM has recognised and embraced the addition of electric motorcycles to our various FIM World Championships, which represents an exciting and new chapter across all disciplines. We are therefore delighted to see electric bikes racing against combustion engine motorcycles in the FIM World Supercross Championship.”

Adding further technical detail, the FIM International Technical Commission and FIM Motocross Commission highlighted the extensive work undertaken to ensure parity and fairness.

The FIM International Technical Commission (represented by Roland Berger) and the FIM Motocross Commission (represented by Antonio Alía Portela) said: “Over the summer, our two Commissions worked to ensure a fair balance of performances and an equivalence of technologies that allows electric motorcycles to compete alongside internal-combustion motorcycles in both the SX1 and SX2 classes. The process included extensive work both on and off the track. All motorcycles were thoroughly tested on a test bench, where a detailed analysis of all power and torque curves was carried out to define the equivalence of technologies.” 

Electric motorcycles will compete against combustion motorcycles at Round 01 of the 2025 FIM World Supercross Championship in Kuala Lumpur, Malaysia.

Kurt Nicoll, Vice President of Race Development, World Supercross, added: “This announcement delivers exactly what we set out to achieve – a championship that embraces innovation while guaranteeing fairness. The FIM has built a framework that lets electric and combustion machinery compete side by side, which is groundbreaking. Fans are about to see something truly new: two technologies battling head-to-head on equal terms. It’s a historic moment that will make the 2025 World Supercross season our most thrilling yet.”

With regulations locked in, fans and teams alike can look forward to a season unlike any other – one where electric and combustion bikes race head-to-head on equal footing, redefining the future of the sport.
