Jason Anderson
Number Plate: 21
DOB: 17/02/1993
Nationality: American
Team: Pipes Motorsport Group
Jason has been a Pro supercrosser since 2011 he won the 250SX title in 2014 and then scooped the coveted 450SX crown in the United States in 2018, joining an exclusive list. JA21 has ridden factory Husqvarna and Kawasaki machinery in his long career so far and has won with three different bikes. Anderson is fast-as-hell but is also well known for his aggressive and uncompromising approach: if there is a hard and gripping battle on track then Jason is sure to be playing his part.

Gregory Aranda
Number Plate: 20
DOB: 19/02/1989
Nationality: French
Team: Team GSM
Greg is a name familiar to many supercross fans and especially those in his country. Outside of the USA, France is perhaps the next spiritual home of supercross. The French have a strong national series and one of the biggest annual supercross fixtures, hosted in the capital city of Paris. Aranda has been setting fast laps and fighting for trophies nationally and internationally (he was an FIM MXGP World Championship racer and has one MX2 podium finish on his CV) for fifteen years. Experience and a supercross specialist: watch out for his racecraft.

Ryan Breece
Number Plate: 200
DOB: 16/07/1995
Nationality: American
Team: MotoConcepts Racing
Fast and gnarly stadium dirtbike action? Ryan will be there! This experienced American has ripped dirt in both the United States and in Arenacross competition (‘AX’is a smaller, more compact and frenetic version of supercross) and has taken his speed across the globe. From his home country to the UK to Brazil and now World Supercross: Breece is a name that hardcore followers of the sport will easily recognise and might be a fresh favourite for the new supercross fans.

Justin Cooper
Number Plate: 32
DOB: 31/08/1997
Nationality: American
Team: Wildcard
When the gate drops and the rush for the holeshot fires-up then watch out for Justin, who makes his debut in the championship this year. The American has carved a career for steady excellence and consistency. He racked-up victories and a series of top five results to own a 250SX title in the United States in 2021 and then jumped into the 450 division (SX1) where he has been a regular contender for podium trophies. An accomplished motocrosser, his Motocross of Nations representation for Team USA in 2022 is also a career-highlight. His high standards and strict demands of his form and fitness are bound to impact the leading positions of World Supercross.

Christian Craig
Number Plate: 28
DOB: 19/07/1991
Nationality: American
Team: Honda Racing
Watch Christian for a lesson on technique and supercross supremacy. There is unlikely to be many faster and more comfortable riders through the dreaded ‘whoops’ sections of tracks; the area that often makes such a difference for lap-times and passing opportunities. Christian has won a 250cc (SX2) title for Yamaha in the USA and has a lengthy and distinguished career in the sport. Injuries have dented his pursuit for even more trophies … but ‘CC’ is still a reference for many, whether he’s caressing the full power of a 450cc bike or manhandling the agility of a 250.

Vince Friese
Number Plate: 719
DOB: 19/10/1990
Nationality: American
Team: Stark
There is unlikely to be a quiet race if Vince is rolling into the gate. On-track clashes and intense scrapping for positions have defined the ‘Friese Experience’. Sometimes the ‘noise’ has obscured the fact that Vince is a rasping and accomplished supercrosser who has posted top results at the highest echelons of the sport. His slightly unpredictable form means that Friese could be duelling for silverware or bringing the mid-pack heat. He is just as formidable either in SX1 or on electric machinery. Vince, the 2025 AMA Arenacross champion, will be bringing the buzz.

Justin Hill
Number Plate: 46
DOB: 07/05/1995
Nationality: American
Team: Venom Bud Racing Kawasaki
The younger of the Hill brothers, Justin is another former Supercross champion to form-up in World Supercross. He won races on both 250SX coast competitions in the United States, including an East title in 2017. Justin transitioned to the 450SX division (SX1) where he continued to mix performances of baffling brilliance with a tendency to also make up the numbers. Hills’ unpredictability is part of his lofty entertainment factor. This, and his often-exceptional ability on a dirtbike. One of the authentic dark horses of World Supercross who is expected to be challenge for the top three places.

Henry Miller
Number Plate: 29
DOB: 22/05/1997
Nationality: American
Team: Rick Ware Racing
Henry has been a supercross and motocross Pro since 2016 and has littered the classifications of 250SX (SX2) and 450SX (SX1) in the United States during that period. His keenness for competition and search for action as one of the leading privateer figures on the scene means he is a welcome and eager addition to the World Supercross roster having races in the championship in 2022 and 2023. Henry brings experience, and also significant edge to the field thanks to his outings in the cut-and-thrust of Arenacross (a more compact, frenetic and intense version of supercross staged in small stadia).

Austin Politelli
Number Plate: 98
DOB: 11/08/1994
Nationality: American
Team: MotoConcepts Racing
As a California, Austin knows all about speedy, hardpack tracks and the allure of supercross. He also knows a thing or two about style and looking cool on the bike while pushing for head-turning results. As a privateer he’s persisted with 250SX West Main Events, dabbled with the 450SX class in the United States and also tried to bring some extra aggression to the Arenacross series (a more compact, frenetic and intense version of supercross staged in small stadia). Austin has recently taken on the challenge of pushing a Stark VARG to its limits but will be on track hitting the clock for MCR in World Supercross.

Quentin Prugnieres
Number Plate: 319
DOB: 11/05/2005
Nationality: French
Team: Venom Bud Racing Kawasaki
What can Quentin produce in World Supercross this year? It’s a curious question, considering the youngster has been catching the eye for the last two seasons as an FIM MX2 Motocross World Championship rider and also appearing in the premier class of MXGP. He’s had to bounce around three teams (and different bikes) in that time due to circumstances beyond his control, indicating that he can adapt fast and still maintain a competitive rate of knots despite his youth: he’s one of the youngsters in World Supercross. More French supercross potential is coming up.

Ken Roczen
Number Plate: 94
DOB: 29/04/1994
Nationality: German
Team: Pipes Motorsports Group
Is there a more recognisable international dirt bike racing icon than Ken Roczen? In motocross and supercross circles the ‘94’ number plate is almost as strong as the ‘46’ for MotoGP. An FIM Motocross World Champion, American motocross champion and 250SX (SX2) title holder as well as a Motocross of Nations winner and, of course, two World Supercross crowns: the German has accolades well beyond his United States and Florida base. Ken is a father of two, but the energy and the enthusiasm he brings to his day job is boyish and brilliant. He is elite: both in his racing intelligence and his technique. He is individualistic and charismatic and when he is physically 100% then there is almost nobody who can stop him. Still taking chequered flags wherever he goes, Roczen has been one of the megastars of the sport ever since he burst onto the scene as a 15 year old in 2009.

Joey Savatgy
Number Plate: 17
DOB: 19/02/1994
Nationality: American
Team: Honda Racing
Joey should somehow have more than a 250SX (SX2) championship runner-up medal and three Main Events victories. If talent and personality were the main ingredients for championship success then Savatgy would be a multiple winner but the Georgian is also an example of how top flite motorsport is very transient, and the next generation of stars are just waiting to come along. Joey has nevertheless forged a lasting career where the bright moments have reminded fans and spectators of his capabilities on two wheels and is one of the most consistent in the series. A supporter and believer of World Supercross and happy to spread supercross to a wider audience; Joey is a significant racer in the gate.

Devin Simonson
Number Plate: 88
DOB: 20/06/2001
Nationality: American
Team: Rick Ware Racing
Devin has been gliding and grafting in the point-scoring positions of elite level supercross in the United States and has been one of the prominent performers for Yamaha’s ClubMX team. He has rubbed dirtbike plastics in both the 450SX and 250SX divisions in his homeland but has also been open to extending his supercross education to an international spotlight. Good starts could bring the North Carolinian into play … but he’ll certainly be pushing for every single place until the flag regardless.

Jordi Tixier
Number Plate: 911
DOB: 02/11/1991
Nationality: French
Team: Team GSM
Jordi excelled in motocross early in his career. He was European champion and then 2014 FIM MX2 World Champion in 2014 for one of the most exciting title finales seen in the sport. Whether attempting to set the speed in Grand Prix or other national motocross series like Germany’s highly competitive ADAC MX Masters, Jordi has maintained his love of supercross and has been a mainstay on the French and European circuit. He recently took a podium finish in the 2025 French championship in preparation for his blast at World Supercross.

Eli Tomac
Number Plate: 1 [red]
DOB: 14/11/1992
Nationality: American
Team: Wildcard
The World No.1 supercross rider—there might be longer names in the worldwide spread of Supercross but hardly any get bigger than Eli Tomac. He has won championships in both 450SX (SX1) twice, with two different manufacturers, and 250SX (SX2) and has multiple motocross titles in the United States. Want more? Then try the fact that he’s the second most victorious rider in 450SX history. Eli is no stranger to supercross overseas and to World Supercross and it’s beyond cool to have this immensely popular athlete back on the slate. Hard, uncompromising with his speed (the Tomac ‘Beast Mode’ has been an unbreakable rhythm for a decade) but also fair and respectful, Eli is one of the genuine all-timers with nothing left to prove.

Tom Vialle
Number Plate: 16
DOB: 28/10/2000
Nationality: French
Team: Wildcard
Tom Vialle is the most successful and decorated French dirtbike racer of the decade. He made a splash for Red Bull KTM as a virtual unknown in 2019 when he became FIM MX2 World Championship rookie of the year and a GP winner in his debut season, The following year he won the first of his two MX2 world titles. Chasing his dream in Supercross he moved to the United States for 2023 and promptly stamped two 250SX (SX2) East crowns. An electric starter and a smart racer, the 450cc category awaits as the next boundary for Vialle to leap.

Cooper Webb
Number Plate: 2
DOB: 10/11/1995
Nationality: American
Team: Wildcard
The current top dog in American Supercross. Cooper won his third 450SX (SX1) championship in 2025 and his first for Yamaha after two crowns with KTM in the United States. ‘Coop’ turned Pro back in 2013 while he was 17 and although it feels like he has been a race winner and title contender for an age, he is only just on the edge of his ‘30s. From 2014 he has finished in the top three of a 250SX or 450SX championship eight times: on five occasions as #1 from both categories. It’s an immense record of achievement. Cooper also won the high profile supercross event in France towards the end of 2024. A family man, Webb is fully committed and applies the highest demands to his preparation and racing. The relentlessness of his approach and strategy means he ‘stalks’ the opposition and churns out a series of unflinching results. Either beat Cooper (good luck) or don’t dare make a mistake … otherwise you’re his.

Jorge Zaragoza
Number Plate: 99
DOB: 30/05/1996
Nationality: Spanish
Team: Stark
Initially touted as Spain’s next big motocross star in the early ‘10s, Jorge’s career entered a different sphere when injury and a lack of opportunity kept him out of the FIM Motocross World Championship limelight. His tidy and attractive riding style meant he was an effective fit for supercross and arenacross (a more compact, frenetic and intense version of supercross staged in small stadia), and he also became a useful test rider and racer for Stark as they honed their Stark VARG electric bike for competition, winning the FIM E-Xplorer championship.
