Finer details on the 2025 World Supercross Championship (WSX) structure have surfaced following a recent WSX Latitude Summit, which indicates substantial updates in regards to participating teams and venue locations for its fourth season, including the cancellation of London’s previously-announced British GP.

Information has been circulated following the WSX conference – which included stakeholders of the SX Global-led series – with a six-team roster breaking cover, among a detailed breakdown on the proposed, expanded six-round calendar.

Next year will almost certainly see WSX commence with a Malaysian GP in Kuala Lumpur on October 18, followed by round two in Argentina with the Buenos Aires City GP on November 8. It appears that Vancouver, Canada, will remain on the schedule for round three on November 15, before traveling to San Jose in Costa Rica for round four on November 22.

Round five of the season will take place with the Australian GP on the Gold Coast come November 29 – expected to clash with a round of the domestic series – and then South Africa will host the finale in Cape Town on December 13. Officially, only South Africa, Australia and Argentina have been announced, albeit without dates being confirmed publicly.

A high-profile British Grand Prix had also been announced at London Stadium, but an announcement from the organization today has confirmed it has been removed from the calendar, with the venue having been unable to ‘meet key requirements necessary to stage the event’.

“Missing out on London this year is a real blow,” commented WSX CEO, Tom Burwell. “The UK fans have been nothing short of exceptional and we know how much anticipation there was around the event. We exhausted every option to make it work, but ultimately, circumstances outside our control at the stadium made it impossible to deliver the event.”

It adds to the skepticism surrounding WSX, which has managed to deliver a total of eight relatively successful events since its introduction three seasons ago, but has been largely clouded by calendar revisions and a reduction in licensed teams, which began with 10 in 2022 and is down to six following the exit of ClubMX, MDK Motorsports and Honda Nils last year, as well as CDR ahead of the 2025 season.

Just six of the inaugural teams remain, including MotoConcepts Racing, Fire Power Honda, Bud Racing, Pipes Motorsport Group, Team GSM, and Rick Ware Racing. Notably, the team that picked up the rider’s championship last year with Eli Tomac – Craig Dack Racing (CDR) – appears to be departing WSX altogether in order to focus on its Australian operations.
