The 2025 FIM Speedway GP of Great Britain in Cardiff has been withdrawn from next season’s calendar.
It was no longer viable, said Warner Bros Discovery (WBD) Sports.
It said a complex economic landscape had had an impact on the event and its contributing stakeholders, when faced with ever-increasing costs and declining attendances.
The decision has been made in close consultation with the Fédération Internationale de Motocyclisme.
There will still be 10 rounds across the 2025 season as WBD Sports and the FIM announce that a double-header will be staged in Manchester on June 13 and June 14.
Jean-Baptiste Ley, motorsport events director at WBD Sports, said: “Firstly, I would like to thank all our partners who have helped us to stage a fantastic sporting event at the Principality Stadium in Cardiff in recent years.
“I would also like to place on record that Warner Bros. Discovery Sports remains committed to delivering an action-packed, engaging 2025 FIM Speedway GP series that can be enjoyed by millions of fans.
“In 2024, we had record numbers of fans watching the FIM Speedway GP series on our platforms and a host of sold-out events, as well as staging racing in front of nearly 50,000 fans at PGE Narodowy in Warsaw (Poland), the world’s biggest speedway attendance in 2024.
“In 2025, we are incredibly excited to bring the FIM Speedway GP series to the iconic National Speedway Stadium in Manchester, a true heartland of the sport, meaning British fans can still watch their favourite riders live and in-person next season as part of an exciting double-header.
“The difficult but necessary decision to replace Cardiff on the 2025 calendar, made in close consultation with the FIM, has not been taken lightly.
“However, a combination of logistical challenges, rising costs impacting the event and its contributing stakeholders, and declining attendances have prevented us from positioning Cardiff as an event that met commercial, or spectator attendance targets post-Covid.
“It is a decision we have made for commercial reasons and a move that ensures the long-term sustainability of the series.
“We will continue to deliver on our plans to capitalise on the popularity of speedway elsewhere and we support the sustained expansion of the sport at all levels of the SGP pyramid – ensuring we provide an even more compelling product for fans while helping the sport to grow even further.”
The 2025 FIM Speedway Grand Prix season will start with the FIM Speedway GP of Germany on Saturday, May 3, when Polish world champion Bartosz Zmarzlik bids to win a record-equalling sixth FIM Speedway World Championship.
