Five storylines to follow in World Supercross 2025

From riders stepping up a class, to those riding new machinery, there are plenty of talking points ahead of this year’s championship. Defending champions return and those riders seeking revenge – plus a new all-electric team join the series.

Stepping Up

One of the most anticipated debuts in recent supercross history, as American star Haiden Deegan will make his 450cc (SX1) debut at the Buenos Aires City GP before heading Down Under for Round 3 at the Australian GP (29 November). Deegan, 19, has taken the sport by storm in the 250 class and will now step up to the premier division for the first time ever, marking a watershed moment for global supercross.

The American superstar, will line up alongside giants of the sport, including Eli Tomac, Cooper Webb, Ken Roczen, Jason Anderson and Justin Cooper for the very first time on a 450 bike. It promises to be an electrifying new chapter in his already headline-making career.

Changing Teams

Experienced rider Anderson will make his World Supercross debut but he will do so with a new team. Anderson aced the AMA 450SX premier class back in 2018 and has been a factory KTM, Husqvarna and Kawasaki rider in the last ten years. However, he tackles World Supercross with the Pipes Motorsports Group and with Suzuki machinery – the brand he represented at the start of his career. Meanwhile, Tomac, one of the most decorated athletes in the sport’s history with four 450MX championships and two 450SX crowns to his name, will make his debut for his new KTM team.

Fierce SX2 Battle 

There are some cracking battles for the title in the 250cc (SX2) class. Max Anstie is one of Supercross’ most well-travelled stars. Born in Great Britain, based in the United States, and already a World Supercross Champion. He is counting on that wealth of knowledge to reclaim the SX2 crown he first secured in 2023 and close out 2025 on a high with Team GSM powered by Star Racing. He will face some stiff competition from Rick Ware Racing’s Coty Schock and Enzo Lopes while Shane McElrath is also a returning champion, having won the title in 2022 and 2024. He has 12 years of Pro experience in the United States where he rode for some of the biggest and most prestigious teams in supercross.

Causing a Spark

The governing body, Fédération Internationale de Motocyclisme (FIM) confirmed the official regulations that will allow Stark Future and its groundbreaking electric Stark VARG MX 1.2 to line up against traditional combustion bikes for the first time in the 2025 World Supercross Championship. Ridden by Vince Friese and Jorge Zaragoza in SX1 and Lance Kobusch and Michael Hicks in SX2, Stark could cause a few upsets with their lighting starts. Four-stroke combustion engines have been ruling off-road racing since the first years of the century – but an electric world champion in the coming seasons? Don’t disconnect the idea. 

A Global Stage

The series embarks on a deliberately wide-ranging schedule that spans five continents to take supercross to new fans. The season kicks off in Argentina (Buenos Aires), then heads to Canada (Vancouver), Australia (Gold Coast), Sweden (Stockholm) and finishes in South Africa (Cape Town). This expansion matters for several reasons: it tests riders and teams across different time zones, surface types and spectator cultures; it broadens the fan-base beyond the traditional U.S./Australian markets; and it raises the logistical stakes for teams. Watch how the riders adjust to different locations and conditions.
