James Stewart Jr.

Amateur and Lites Class

Stewart was born in Bartow, Florida and currently resides in Haines City, Lake Hamilton, Florida. His father, James Sr., was a motocross enthusiast and introduced his son to the sport at the age of three. Stewart entered his first motocross race when he was four years old.

Winning eighty-four Amateur national titles all before the age of 16, he debuted as pro in 2002. While crashes and rookie mistakes kept him from winning the 2002 125 West Supercross title, he went on to dominate the 2002 125cc national championship and was named the 2002 AMA Rookie of the Year. He was also named one of "20 Teens Who Will Change the World" in the April 2003 issue of Teen People magazine.

Stewart went on to win the 2003 125 West Supercross Championship but suffered a severe crash at the season ending 125 East/West Shootout in Las Vegas, Nevada. With his collarbone broken in two places as a result of the crash, he was forced to sit out the first few rounds of the 2003 AMA Motocross series, losing the hope to win the championship, although he won every single race he competed in after coming back from that injury.

In 2004 he won both the 125 East Supercross title and the 125 Outdoor national title, only losing one moto to Mike Brown in the latter due to a broken clutch cover.

Supercross

On April 2, 2005, at Texas Stadium (in only his 3rd race), Stewart captured his very first Supercross victory. He would go on to record many more victories throughout 2005 and 2006, and he eventually won the 2007 Supercross Championship. He was unable to finish the 2007 National series due to a knee injury.

2008

Stewart missed the last 15 races of the 2008 Supercross season due to a knee injury caused by a crash into Dale White #7.

2009

Stewart signed with L&M Yamaha racing for the 2009 season, replacing Chad Reed for the supercross season. In the latter season Stewart and Chad Reed were involved in the tightest (and sometimes heated) points race of Stewart's career. Stewart won 11 of the 17 events. On May 2, 2009, at Sam Boyd Stadium in Las Vegas, Stewart won the 2009 Supercross Championship by a margin of 4 points over Reed (377-373).

2010

After a strong charge by Supercross class rookie Ryan Dungey at the opening round at Anaheim, Stewart captured the lead on lap 18, going on to take the win . In round 2, Stewart was involved in a crash during his heat, but came back to win the Last Chance Qualifier. In the final, a collision with Chad Reed caused both riders to fall. Reed's left hand was pinned under Stewart and Reed pushed Stewart's head off his arm, in what some deemed to be a physically aggressive manner. Controversy followed in the pits when Stewart pushed Reed's bike off its stand, resulting in an official warning from the AMA. Still struggling with injury Stewart finished 3rd behind Ryan Dungey and Josh Hill in round 3. Stewart retired from the season after having surgery from Dr. Arthur Ting for a broken right scaphoid.

Stewart's wrist injury took longer than expected to heal, leaving him out of the 2010 Motocross series, although he did return for one round at Unadilla where he placed third in the first moto and retired early from the second moto, citing bike setup issues and exhaustion.

On January 8, 2011 Stewart made his return to Supercross placing 3rd in the Anaheim season opener. The next week at Phoenix on January 15, he won his first main event in over a year, leading all 20 laps over Ryan Villopoto, who trailed close behind for most of the race.
