Throughout the history of AMA Supercross, Suzuki has experienced periods of dominance, long championship droughts, and unexpected returns to the top. From Mark Barnett delivering the brand’s first-ever title in 1981 to Ken Roczen ending a sixteen-year wait in 2026, Suzuki’s legacy in the premier class has been shaped by legendary riders, dramatic title fights, and multiple generations of supercross stars.
These are all of Suzuki’s premier class AMA Supercross championships.
1981: Mark Barnett delivers Suzuki’s first title
The 1981 season marked the beginning of Suzuki’s rise in AMA Supercross. With a line-up featuring Kent Howerton, Mark Barnett and Darrell Shultz, Suzuki dominated much of the championship and quickly established itself as the team to beat.
After opening the year with an incredible run of victories, Barnett eventually emerged as the leader of the title charge. While injuries sidelined Shultz and Howerton lost ground in the standings, “The Bomber” took control with crucial wins in Houston, Pontiac, Kansas City and Los Angeles.
The championship was sealed at the Los Angeles Coliseum, where Barnett delivered another dominant victory in front of more than 60,000 fans. It was Suzuki’s first-ever AMA Supercross title, with Barnett winning six of the eleven rounds while the brand claimed ten victories throughout the season.
2005: Ricky Carmichael returns Suzuki to the top
After Suzuki’s dominance in 1981, Suzuki had to wait twenty-four years before returning to the top of AMA Supercross. The man responsible was Ricky Carmichael, who captured the title during one of the most anticipated seasons in supercross history.
The 2005 championship opened with enormous hype surrounding Carmichael, Chad Reed and James Stewart Jr.. Stewart’s early injury at Anaheim removed one major contender, allowing Carmichael to capitalize immediately. With five wins in the opening seven rounds, the Suzuki rider built a crucial advantage over Reed.
Although Reed mounted a late-season comeback and Stewart returned to win races, Carmichael managed the points lead with experience and consistency. He clinched the championship in Houston, securing Suzuki’s first modern-era AMA Supercross crown.
The 2005 title also symbolized the final great chapter of the 250cc two-stroke era before the transition to 450 four-strokes permanently changed the sport.
2006: Carmichael survives the ultimate title fight
If the 2005 title brought Suzuki back to the top, the 2006 season cemented Ricky Carmichael’s place at the center of one of the greatest championship battles in AMA Supercross history.
The season immediately intensified with the arrival of James Stewart Jr. aboard Kawasaki’s new KX450F, while Chad Reed remained firmly in contention. The three-way fight stayed alive all the way to the Las Vegas finale.
Carmichael answered with consistency and experience. Stewart may have been the fastest rider overall, and Reed remained a constant threat, but the Suzuki rider minimized mistakes when it mattered most. He also overcame the mid-season fuel controversy that temporarily cost him valuable championship points before the AMA eventually restored them.
The title came down to the final round in Las Vegas, with Carmichael and Reed tied in points and Stewart still mathematically alive. Stewart won the race, but Carmichael’s second-place finish was enough to secure his second consecutive AMA Supercross championship with Suzuki.
Just days before the finale, Carmichael had also announced that 2006 would be his final full-time season, making the title-winning campaign an iconic end to an era.
2010: Ryan Dungey begins a new era
Following the Carmichael years, Suzuki found its next superstar in Ryan Dungey. The rookie entered the premier class in 2010 after taking over the factory Suzuki ride previously occupied by Chad Reed, and immediately proved he belonged among the sport’s elite.
The season initially looked set to revolve around James Stewart Jr. and Ryan Villopoto, but the championship picture changed quickly after injuries sidelined both Stewart and Reed early in the season. Dungey seized the opportunity with remarkable maturity, collecting wins in Phoenix and Anaheim 2 while consistently battling Villopoto for the championship lead.
The decisive moment came in St. Louis, where Villopoto crashed heavily while fighting Dungey for the lead and suffered a season-ending injury. With his main rival out, Dungey secured the championship one round later in Seattle by finishing fourth.
The Suzuki rider became only the second rookie in history to win the AMA Supercross title, restoring Suzuki to the top for the first time since the Carmichael era. He capped off the season with another victory in Las Vegas, confirming the arrival of a new generation.
2026: Ken Roczen ends Suzuki’s drought
After Ryan Dungey captured the title in 2010, Suzuki endured another lengthy drought in AMA Supercross. By the time Ken Roczen returned to the brand in 2023, Suzuki’s factory presence was far smaller than during its glory years.
Roczen had already enjoyed success with Suzuki during his first stint between 2015 and 2016, earning multiple wins and an AMA Pro Motocross title, but his second chapter with the brand seemed more focused on occasional race victories than a serious championship challenge. Injuries and late-season fades had repeatedly denied him a Supercross crown.
Everything changed in 2026. Roczen produced one of the most unexpected comebacks in recent history, erasing a 35-point deficit to enter the final round leading Hunter Lawrence by just a single point. The two riders arrived at the finale tied in victories and podium finishes, highlighting how evenly matched the championship had become.
In the deciding main event, Roczen capitalized on a costly mistake from Lawrence to finally secure his first AMA Supercross championship after thirteen years of trying. The title not only represented the biggest achievement of Roczen’s American career, but also returned Suzuki to the top of AMA Supercross for the first time in sixteen years.
