AMA Supercross Championship
The AMA Supercross Championship, commercially known as Monster Energy AMA Supercross, is an American professional off-road motorcycle racing series sanctioned by the American Motorcyclist Association (AMA).[1][2] It features high-speed races on artificial dirt tracks built inside stadiums and arenas using thousands of cubic yards of dirt, emphasizing jumps, rhythm sections, and whoops sections designed for spectator excitement.[1] The series runs annually from January to May, comprising 17 rounds for the premier 450cc class and regional events for the 250cc class, attracting top riders from nine motorcycle manufacturers on production-based bikes.[1][2] Supercross originated as an indoor evolution of traditional outdoor motocross, with its first professional event held in 1971 at Daytona International Speedway on a temporary track.[2] The format expanded in 1972 to urban stadiums, beginning with the Los Angeles Memorial Coliseum, where the term "Supercross"—a blend of "Super Bowl" and "motocross"—was coined to describe the spectacle.[2] By the 1980s and 1990s, the series grew significantly through increased manufacturer involvement, team sponsorships, and media coverage, solidifying its status as one of the most popular motorsports in the United States and boosting off-road motorcycle sales.[2] The championship is divided into two primary classes: the 450SX Class, the elite division for riders on 450cc motorcycles competing in 17 full rounds to determine a single national champion, and the 250SX Class, for younger or developing riders on 250cc bikes split into Eastern and Western regional series that culminate in separate titles.[1][2] Each event follows a structured format, including qualifying heats, a Last Chance Qualifier (LCQ) for additional spots, and Main Events lasting 15 minutes plus one lap for 250SX or 20 minutes plus one lap for 450SX, with up to 22 riders per final.[1] Special "Triple Crown" rounds feature three Main Events per class, awarding bonus points to intensify competition.[1] Points are awarded based on finishing position, with 25 points for first place tapering down, leading to crowning of champions at the season finale.[1] Notable figures in Supercross history include Jeremy McGrath, who holds the record for seven 250SX championships and 72 career wins in the 250SX class, exemplifying the sport's demand for precision and athleticism.[1] The series has produced global stars and integrates with the AMA Pro Motocross Championship through the SuperMotocross World Championship playoff, combining indoor and outdoor formats for an ultimate title.[2] With events drawing massive crowds and broadcast worldwide, Supercross remains a cornerstone of American motorsport, emphasizing speed, strategy, and rider skill on ever-evolving tracks.[1][2]Origins and History
Early Development
Supercross originated as an indoor evolution of traditional outdoor motocross, with its first professional stadium event held in 1971 at Daytona International Speedway on a temporary track.[2] The format expanded in 1972 when promoter Mike Goodwin organized the first stadium-based motorcycle race at the Los Angeles Memorial Coliseum in California, dubbed the "Superbowl of Motocross." This event featured a modified motocross track constructed inside the venue, drawing over 30,000 spectators and marking a pivotal shift toward urban, enclosed racing formats.[3][4] Marty Tripes emerged as the winner, riding a Yamaha, in what proved to be a successful experiment that blended high-speed racing with entertainment in a controlled environment.[5] This innovation stemmed from the limitations of traditional outdoor motocross, which was heavily dependent on weather conditions and seasonal schedules, often restricting events to warmer months and rural tracks. By moving races indoors to stadiums, organizers like Goodwin aimed to mitigate rainouts, enable year-round competition, and attract larger urban audiences who could attend without the unpredictability of open-air venues. This transition not only extended the racing calendar but also intensified the sport's appeal by incorporating tighter, more technical layouts that emphasized rider skill and bike handling in confined spaces.[6][7] The American Motorcyclist Association (AMA) began formal involvement in 1974 by sanctioning the first official Supercross series, initially known as the "Yamaha Super Series" due to sponsorship. Comprising just three rounds—held at Daytona International Speedway, the Houston Astrodome, and the Los Angeles Memorial Coliseum—this short championship introduced a points-based system to crown national titleholders, with riders accumulating scores across motos to determine overall standings. Dutch rider Pierre Karsmakers, competing on a Yamaha, secured the inaugural 250cc Western Region title by winning two of the three events, establishing himself as the first AMA Supercross champion and highlighting the series' growing international draw.[8][9][10]Evolution and Key Eras
The 1980s marked a significant boom for the AMA Supercross Championship, as stadium events transformed into major spectacles that drew large crowds and elevated the sport's popularity nationwide.[11] This era saw expanded schedules and increased attendance, with the series growing to 17 races by 1980, solidifying its role as a premier motorsport entertainment product.[12] Dominance in the 500cc class was exemplified by riders like Ricky Johnson, who secured seven AMA national championships during the decade, contributing to the sport's rising profile through high-profile performances.[13] In the 1990s, the championship underwent promotional shifts, including the bankruptcy of Mickey Thompson Entertainment Group and the subsequent acquisition by Pace Enterprises, which streamlined operations and fostered stability. The decade also witnessed the growing presence of international riders, highlighted by French rider Jean-Michel Bayle's successes, including the 1991 250SX championship, and continuing with the first international podium in the 125SX class by Mickael Pichon in 1993, leading to increased global participation and 279 international podiums by the early 2020s.[14] The 2000s brought further professionalization, highlighted by Feld Entertainment's 2008 acquisition of Live Nation Motor Sports, which integrated Supercross into its portfolio alongside events like Monster Jam and enhanced production values.[15] This ownership change coincided with Monster Energy becoming the title sponsor that same year, boosting visibility through aggressive marketing and aligning the series with high-energy branding.[16] Entering the 2010s and 2020s, the championship adapted to technological and external challenges, including the full transition to four-stroke engines in the premier class, reclassified as 450cc to accommodate equivalents of the former 500cc two-stroke displacement by the mid-2000s, with formal rule combinations for 250cc two- and four-strokes implemented in 2008 for broader amateur and pro alignment.[17] The COVID-19 pandemic disrupted the 2020 season, prompting a "bubble" format in Salt Lake City to complete the remaining rounds without spectators, while the 2021 schedule featured condensed mid-week races and venue adjustments to navigate ongoing restrictions.[18] Key milestones included the introduction of the first Triple Crown event in 2019 at Angel Stadium, featuring three main events per round to intensify competition.[19] Attendance reached new heights, with total series figures exceeding 850,000 fans in 2023, 828,796 in 2025 (the fourth-highest ever), and the 2025 season opener featuring five past champions, underscoring the sport's enduring cultural impact.[20][21]Race Format and Rules
Event Structure
A typical AMA Supercross event unfolds over a single evening in a stadium setting, progressing through structured sessions that determine starting positions and culminate in the main race. The day begins with timed practice sessions for each rider class, allowing competitors to familiarize themselves with the track and set initial qualifying times. These sessions are followed by heat races, where riders are grouped based on practice results and compete in shorter races to advance to the main event or further qualifiers.[1] Riders who do not qualify directly through heats enter last-chance qualifiers (LCQs), intense short races that offer a final opportunity to secure a spot in the main event, which features the top 22 riders in each class racing for 15 minutes plus one lap (250SX) or 20 minutes plus one lap (450SX) under stadium lights on a dirt track filled with jumps and obstacles. In select events, the triple crown format replaces the standard single main event with three separate mains per night (10 minutes plus one lap for 250SX; 12 minutes plus one lap for 450SX); points from all three are aggregated using Olympic-style scoring to determine the overall winner, adding strategic depth and endurance demands.[1][22] Points for the overall championship are awarded solely based on finishing positions in the main event, with 25 points for first place, 22 for second, 20 for third, 18 for fourth, 17 for fifth, 16 for sixth, 15 for seventh, 14 for eighth, 13 for ninth, 12 for tenth, 11 for eleventh, 10 for twelfth, 9 for thirteenth, 8 for fourteenth, 7 for fifteenth, 6 for sixteenth, 5 for seventeenth, 4 for eighteenth, 3 for nineteenth, 2 for twentieth, 1 for twenty-first, and 0 for twenty-second. Gate selection for the main event is determined by qualifying results from heats and practice, with the fastest qualifiers earning the best starting positions inside the 40-rider gate. Tiebreakers for championship points standings prioritize wins, followed by second-place finishes, and so on, ensuring fair resolution in close contests.[1][22] These events emphasize intensity and precision, typically lasting 4 to 6 hours from opening ceremonies to the final checkered flag, all conducted under artificial lighting to accommodate evening schedules and large crowds.Track Specifications
Supercross tracks are artificial dirt courses constructed indoors within stadium facilities, distinguishing them from outdoor motocross by their compact, stadium-optimized design that amplifies obstacles for spectator viewing. These tracks utilize approximately 5,500 cubic yards of dirt, transported in about 500 truckloads, to create a racing surface covering around 70,000 square feet. The dirt is typically layered to a depth of 8 to 15 inches over a protective base, allowing for the formation of jumps and berms while adapting to the underlying stadium floor, which may consist of concrete, Astroturf, or grass.[1][23][24] The construction process begins with laying thousands of plywood sheets—often 6,800 in total—to shield the venue floor from damage, followed by dumping and shaping the dirt using heavy machinery such as bulldozers and graders over a period of about 60 hours with crews operating 30 pieces of equipment. Specialized track-building teams, like DirtWurx, handle the weekly disassembly and reconstruction for each event, stockpiling excess dirt centrally in the stadium and sculpting the layout to fit the facility's dimensions, ensuring proper drainage and adaptation to varying floor types. This labor-intensive rebuild allows tracks to evolve per venue while maintaining core Supercross characteristics, such as a standard racing lane width of 20 feet and a starting straight of 150 to 375 feet.[1][25][26] Key track elements include whoops sections, consisting of a series of small, closely spaced bumps about 3 feet high that riders skim across at high speeds to maintain momentum; rhythm sections, featuring irregular sequences of smaller jumps that demand precise linking of doubles or triples; and large jumps like triples spanning up to 70 feet, where riders can achieve airtime of 35 feet. Additional features encompass step-up jumps, with elevated landings requiring upward trajectory control, and step-down jumps, involving downhill descents that test braking and balance. Tracks average 0.25 to 0.5 miles in lap length, incorporating 10 to 15 turns—many banked as berms for cornering speed—and elevation changes reaching up to 50 feet through jump combinations and undulations.[1][27][28][29] Safety features have evolved to mitigate the high-impact nature of these compact courses, including foam pits beneath major jumps to cushion hard landings and reduce injury risk from overshoots, alongside foam-block barriers such as tuff blocks—over 700 per track—positioned at corners and edges to absorb collisions softly. These elements, combined with flaggers monitoring conditions and minimum width standards of 20 feet (with exceptions for flow-enhancing sections), ensure safer navigation amid the track's demanding layout, though concrete proximity remains a challenge in stadium settings.[1][22][30]Rider Classes and Eligibility
The AMA Supercross Championship is divided into primary professional classes based on engine displacement and rider experience levels, with the 450cc class serving as the premier division for elite competitors using production-based single-cylinder motorcycles limited to 249-450cc four-stroke engines or 150-250cc two-stroke equivalents.[22] The 250cc class, designed for emerging professionals, utilizes engines up to 250cc four-stroke or 125cc two-stroke and is split into East and West regional series to accommodate a larger field of younger riders while managing travel demands.[22] These classes ensure competitive balance by restricting multi-class entries per event and enforcing homologation standards for all motorcycles.[22] Eligibility for participation requires riders to hold a valid AMA Supercross license, which demands a minimum age of 16 years as of the 2025 season, increasing to 17 in 2026 and 18 in 2027, along with proof of physical fitness, primary medical insurance, and completion of a neurocognitive baseline test within the prior two years.[22] For the 250cc class, riders must qualify through the AMA Road to Supercross program by earning advancement points—such as four points for top-20 finishes in select Pro Sport classes at events like the Monster Energy AMA Amateur National Motocross Championship—over a 24-month period, with a two-season window to apply for the license.[31] 450cc eligibility builds on this foundation, requiring prior qualification in the 250cc evening program or possession of a 450cc license from 2022-2024, alongside adherence to the AMA Substance Abuse Policy prohibiting performance-enhancing substances.[22] All riders assume responsibility for equipment compliance, including engine displacement limits, and must undergo technical inspections.[22] Rookie status is assigned to first-year professionals in a class, influencing starting gates and seeding, while veteran riders benefit from points carryover from the previous season, which determines championship standings and playoff qualification for the top 30 in each class at season's end.[32] The progression pathway from amateur ranks typically begins with regional and national events like the Loretta Lynn Amateur National Motocross Championship, where strong performances in Pro-Am classes accumulate the 60 points needed over 18 months for a professional motocross license, often leading to team contracts and entry into feeder series such as SMX Next.[33][31] Gender inclusion policies allow women to compete in the open 250cc and 450cc classes under the same eligibility criteria, with no separate women's division in the AMA Supercross Championship, though former or current professional female riders may participate in affiliated women's motocross classes like WMX for skill development.[34] International riders gain eligibility through FIM license reciprocity, requiring approval from their home federation, submission of a Confirmation of International Rider Eligibility form, and compliance with all AMA standards; numbers 100-110 are reserved for top international participants.[22] Appeals for expired licenses or disputes are handled through AMA processes to maintain fairness.[22]| Class | Engine Displacement Limits | Key Eligibility Notes |
|---|---|---|
| 250cc | 0-250cc (4-stroke); 0-125cc (2-stroke) | Minimum age 16; Road to Supercross qualification; East/West split; 4-year champion tenure limit.[22] |
| 450cc | 249-450cc (4-stroke); 150-250cc (2-stroke) | Premier class; prior 250cc experience required; no multi-class per event.[22] |
Season Calendar and Venues
Annual Schedule
The AMA Supercross Championship season typically spans from January to May, encompassing 17 rounds held weekly in stadiums across the United States to capitalize on winter and spring weather patterns in southern and western regions. The 2025 season began on January 11 at Angel Stadium in Anaheim, California, and concluded on May 10 at Rice-Eccles Stadium in Salt Lake City, Utah, crowning champions in the 450cc and 250cc classes following a rigorous series of high-stakes races.[35] In the 250cc class, the schedule features a regional split between Eastern and Western divisions to accommodate geographic and logistical demands, with each division racing seven exclusive rounds and participating in three East-West Showdown events for a total of 10 scoring opportunities per region. These showdowns, held at select venues like Indianapolis, Philadelphia, and Salt Lake City, bring top riders from both coasts together for head-to-head competition, adding intensity to the regional championships. The 450cc class, by contrast, contests all 17 rounds as a unified national series.[36][37] Schedule planning is shaped by key logistical factors, including stadium availability amid competing events like NFL games, avoidance of harsh winter weather by prioritizing warmer climates early in the season, and considerations for international riders who compete in the FIM Motocross World Championship (MXGP), with the calendar designed to limit direct overlaps during peak periods. Championship points are awarded cumulatively across all applicable rounds, with 25 points for first place tapering to 1 point for 21st; ties are resolved first by the greatest number of main event wins, followed by the most second-place finishes, and so on, until a decisive outcome is reached.[1][22] A notable recent adjustment occurred in 2024, when the season finale shifted to a Saturday night format to align with primetime television windows, improving broadcast accessibility and viewer engagement on networks like NBC and Peacock. This change, part of broader efforts to enhance media coverage, was retained for subsequent seasons including 2025.[38][39]Current and Former Venues

The broadcasting of the AMA Supercross Championship began with limited local coverage in the 1970s and 1980s, primarily through affiliates of ABC and CBS, which aired highlights and select events to introduce the sport to broader audiences. ABC's Wide World of Sports provided some of the earliest national exposure, featuring motocross-derived events like Superbikers in the late 1970s and early 1980s, helping to elevate the series' visibility beyond regional markets.[60][61] ESPN marked the first significant national television milestone in 1983, offering dedicated coverage that transitioned the series from sporadic highlights to more structured programming, laying the groundwork for expanded partnerships. By the late 1990s, ESPN established a full partnership starting in 1998, introducing live weekend broadcasts and over 20 hours of annual network airtime, which solidified Supercross as a staple in cable sports programming.[62] The 2000s saw a shift to the Speed Channel (later rebranded as Fox Sports), which began comprehensive coverage around 2005-2006, delivering live and delayed events that boosted viewership ratings to household averages of approximately 0.47 per event by 2006, equivalent to hundreds of thousands of viewers and contributing to the sport's growing mainstream appeal.[63][64] In the 2010s, broadcasting transitioned toward NBC Sports following the network's 2011 acquisition and integration of action sports programming onto platforms like Versus (which became NBCSN), introducing enhanced production values reminiscent of Olympic-level events and further professionalizing the coverage. These evolving TV deals have directly influenced the series' financial growth, driving substantial increases in prize purses from modest totals in the 1980s to multimillion-dollar payouts exceeding $10 million annually in recent seasons through expanded media revenue.[65][66]Championships and Results
AMA Supercross Winners by Year
The AMA Supercross Championship's premier class, known as 450SX since 2008 but tracing its roots to the original 250cc/450 four-stroke division established in 1974, has produced intense competition among top riders. Annual champions are determined by points accumulated over 17 races, with the title often decided in the final rounds due to close battles and unforeseen events like injuries or mechanical issues. Jeremy McGrath holds the record for most 450SX titles with seven, while Ricky Carmichael secured five during a dominant era in the early 2000s. The following table lists all 450SX champions by year, including the rider's manufacturer for context on team and bike influences.[67][68]
Several seasons featured defining rivalries and highlights that shaped the sport's legacy. In 1997, Jeff Emig clinched the title over seven-time champion Jeremy McGrath in a fierce duel, with Emig overcoming McGrath's mid-season injury to win by 36 points amid controversies over track conditions at rounds like Las Vegas. The early 2000s saw Ricky Carmichael's unbeaten streak in 2002, where he won all 15 mains, solidifying his rivalry with Chad Reed, who dethroned him in 2004 after a controversial pass at Anaheim. James Stewart's explosive style led to back-to-back titles in 2007 and 2009, highlighted by his recovery from a 2008 injury that sidelined him for the season. More recently, the 2025 season culminated in Cooper Webb's third championship, edging Chase Sexton by just two points in a nail-biting Salt Lake City finale marred by wet conditions and multiple crashes. These moments underscore the high-stakes nature of the series, where points leads often swing dramatically.[67]
The 250SX class, serving as a proving ground for future stars, has been split into East and West regional championships since 1986 to reduce travel demands on developing riders, with each region's title decided by 8-9 races before a showdown at the season finale. Champions from this class frequently graduate to 450SX contention. The table below lists 250SX East and West winners from 2010 onward, showcasing recent talent pipelines like Jett Lawrence's 2023 West title en route to his 2024 450SX dominance.[67]

World Supercross Winners by Year
The FIM World Supercross Championship (WSX), distinct from the domestic AMA Supercross series, was re-established in 2022 by SX Global, an Australian-based promoter, following a split from the AMA amid efforts to create a truly international circuit. This revival aimed to globalize the sport by hosting events across multiple continents, drawing top riders from the AMA and other regions while operating as a separate entity with its own points system. The inaugural season featured just two rounds—in Cardiff, Wales (October 8), and Melbourne, Australia (October 15)—emphasizing a compact format to test the waters for broader expansion. Ken Roczen of Germany, riding for Suzuki, clinched the 2022 WSX title with consistent podium finishes, marking the first championship under the new structure and highlighting the series' focus on elite, global talent.[69][70] The 2023 season expanded ambitions but faced significant hurdles, including logistical delays and financial pressures that led to the postponement of the planned French Grand Prix and reductions from an initial six-round calendar to three events: Buenos Aires, Argentina (October 28), Vila Real, Portugal (November 4), and Melbourne, Australia (November 25). Low attendance at early international venues compounded challenges, prompting investor concerns and last-minute adjustments by organizers. Despite these issues, Roczen defended his title successfully, securing back-to-back victories with strong performances in the sprint-style races, underscoring the series' appeal to AMA veterans seeking off-season competition without conflicting points. The format emphasized shorter, high-intensity rounds—typically three main events per class over a single weekend—contrasting the AMA's longer 17-round domestic schedule and fostering a more global rider pool that included Europeans and Australians alongside American stars.[71][72][73][74] In 2024, the championship stabilized with four rounds across diverse venues, including Vancouver, Canada (October 26), Perth and Melbourne, Australia (November 23 and 30), and Abu Dhabi, UAE (December 7), attracting a broader international field while maintaining the concise five-to-six round structure planned for growth. Eli Tomac of the United States, on Yamaha, emerged as champion after a tight battle, winning the decisive final round in Abu Dhabi to claim his first WSX title and demonstrating the series' role as a proving ground for AMA pros during the northern hemisphere off-season. The event format continued to prioritize sprint races—two shorter heats plus a longer final per round—allowing for rapid, action-packed weekends that differ markedly from the AMA's extended season, with global stops like Qatar occasionally featured in planning.[75][76][77] As of November 19, 2025, the ongoing season marks a milestone with five planned rounds spanning five continents, starting with the Buenos Aires City GP in Argentina (November 8) at the Oscar and Juan Gálvez Racetrack, followed by Vancouver, Canada (November 15), Gold Coast, Australia (November 29), Gothenburg, Sweden (December 6), and Cape Town, South Africa (December 13). Ken Roczen (Suzuki) won Round 1 and leads the SX1 standings with 85 points after Round 2, ahead of Jason Anderson (Suzuki) at 65 points, in a competitive field that includes AMA crossovers like Haiden Deegan. This structure reinforces the championship's international ethos, with separate scoring from AMA events enabling pros to chase dual accolades, though participation remains voluntary and off-season focused.[78][79][80]| Year | WSX Champion | Nationality | Manufacturer | Key Notes |

Manufacturer Victories
Honda has historically dominated the AMA Supercross premier class (450SX), amassing the most championships and main event victories of any manufacturer. As of the end of the 2025 season, Honda holds a record of over 340 premier class main event wins, far surpassing competitors and underscoring its engineering prowess and factory support through the Honda Racing Corporation (HRC) program.[81] Yamaha follows as the second-most successful brand in terms of titles, with consistent performances driven by factory teams like Monster Energy Star Racing. The Japanese "Big Four" manufacturers—Honda, Yamaha, Suzuki, and Kawasaki—established overwhelming control from the 1980s through the 2000s, capturing nearly every championship during this period. Honda's HRC initiative was pivotal, powering riders to multiple consecutive titles, including four straight wins with Jeremy McGrath from 1993 to 1996. This era saw heavy investments in R&D and rider development, enabling technological advancements in suspension and engine performance that favored Japanese bikes. Suzuki and Kawasaki also contributed significantly, with Suzuki securing back-to-back titles in 2005–2006 via Ricky Carmichael and Kawasaki claiming four straight from 2011 to 2014 with Ryan Villopoto. Since the 2010s, European manufacturer KTM has emerged as a major force, breaking the Japanese stranglehold with five premier class titles and over 20 main event wins, largely through its Red Bull KTM Factory Racing team. KTM's success stems from aggressive expansion into the U.S. market, including the acquisition of Husqvarna, and innovations in chassis design that appealed to riders like Ryan Dungey (three titles, 2015–2017) and Cooper Webb (two titles, 2019 and 2021). In the 2025 season, Yamaha reclaimed momentum with Cooper Webb securing the title aboard the YZ450F, marking the brand's 12th premier class championship and highlighting Star Racing's continued strength.[67]Overall Manufacturer Championships (1974–2025)

Records and Statistics
All-Time Rider Wins Leaders
The all-time wins leaders in the AMA Supercross Championship are determined by the number of main event victories in the premier class (formerly 250cc, now 450cc), reflecting the highest level of competition within the series. Jeremy McGrath holds the record with 72 premier class wins, a mark set during his dominant career from 1989 to 2001, primarily aboard Honda machinery.[82] His total includes 72 wins in the 250cc era, underscoring his versatility across track conditions and bike evolutions. McGrath's record highlights the importance of consistency, as he secured seven championships while competing in an era of expanding schedules and increasing technical demands.[83] Ricky Carmichael ranks fourth with 48 premier class wins, achieved between 1997 and 2007, mostly with Suzuki and Kawasaki. All 48 came in the premier class, with no recorded wins in the 250cc support class during his professional tenure, emphasizing his rapid ascent to elite competition.[84] Known for his flawless execution, Carmichael's career featured undefeated streaks, including winning the first nine rounds of the 2001 season, which contributed to his five premier class titles and cemented his reputation for mental fortitude under pressure.[85] His longevity was influenced by strategic team affiliations and injury management, allowing him to retire at the peak after transitioning from a dominant 125cc phase. James Stewart follows with 50 premier class wins from 2002 to 2014, riding primarily for Kawasaki and Yamaha. Like Carmichael, Stewart's total is entirely from premier events, building on an explosive start in the 125cc class where he won 18 races before promotion.[86] His career narrative revolves around raw speed and aggressive style, marked by two championships and multiple win streaks, though tempered by injuries and suspensions that tested his resilience. Stewart's 50 wins place him third all-time, a testament to his ability to dominate diverse venues despite personal challenges.[87] Among active riders, Eli Tomac leads with 53 premier class wins as of the conclusion of the 2025 season, riding for Honda, Yamaha, and KTM across his career from 2011 onward. Tomac's tally includes 5 wins in the 250SX West class in 2012 en route to the regional title, plus 41 in the premier class, showcasing his progression from support to elite status. His two championships and consistent podium presence highlight factors like adaptive riding technique and cross-training regimens that extended his prime, making him a benchmark for modern longevity.[88] Emerging talent Jett Lawrence, an Australian rider competing for Honda since 2022, has amassed 22 Supercross wins as of the end of the 2025 season, including 13 in the 250SX class across 2021–2023 (with regional titles in the East 2022 and West 2023) and 9 in the premier class.[89] Lawrence's rapid rise, marked by two 250SX regional titles and a 2024 premier championship, introduces international flair to the leaders' ranks, with his technical precision and family racing background (brother Hunter also a champion) positioning him for future climbs. His impact extends beyond wins, influencing global interest in the series through high-profile performances.[90] The following table summarizes the top 10 all-time premier class wins leaders as of the end of the 2025 season, including years active and primary teams:| Rank | Rider | Wins | Years Active | Primary Teams |

Team and Manufacturer Stats
In the AMA Supercross Championship, manufacturers track collective performance through metrics like podium finishes, which reflect overall competitiveness beyond outright victories. Honda holds the record for the most all-time podiums, with 683 in the premier class across the first 700 races held through 2021.[91] This dominance underscores Honda's historical reliability and engineering prowess in high-stakes stadium racing environments. Kawasaki and Yamaha have also amassed significant podium tallies, contributing to the sport's brand rivalries, though exact figures trail Honda's benchmark. Team-level statistics highlight sustained excellence, particularly for factory outfits like Red Bull KTM Factory Racing, which entered the premier class in 2012 and quickly established a strong podium presence through riders such as Ryan Dungey and Cooper Webb.[92] Dungey's 31 consecutive 450SX podiums spanning the 2015–2016 seasons set an all-time record, elevating the team's legacy during a period of rapid ascent. Other notable streaks include Ricky Carmichael's 16 consecutive podiums in the early 2000s, showcasing individual contributions that bolster team metrics.[93] Additional performance indicators include fastest lap records, which demonstrate technological edges in speed and handling. Eli Tomac holds multiple venue-specific fastest laps, including 1:01.954 at Anaheim 1 in an earlier season, highlighting advancements in suspension and power delivery.[94] Rookie achievements further illustrate team development pipelines; Jeremy McGrath secured a record 10 wins during his 1993 rookie 450SX season, a feat that remains unmatched for newcomers transitioning to the premier class.[95] Team structures in AMA Supercross divide into factory squads, fully backed by manufacturers with comprehensive engineering and logistics support, and satellite teams, which receive partial assistance like parts and technical aid while operating independently.[1] These satellite operations allow broader talent access but operate on varied funding scales, enabling diverse entries without full factory resources. Diversity metrics show growing international participation, with riders like Australian Jett Lawrence and French Tom Vialle contributing podiums and championships, enhancing the field's global appeal.[96] In the Women's Motocross (WMX) class, integrated into select Supercross weekends, riders such as Jordan Jarvis have claimed podiums, promoting gender inclusivity amid evolving class formats.[97]| Top Manufacturers by Premier Class Podiums (as of 2021, first 700 races) | Podium Count |
