Motorcycle racing McGrath began racing motocross at the age of 15 after a successful career in
BMX. He placed 8th in the 125cc West Region supercross season of 1989. In 1990, he won his first supercross race and placed 2nd in that season. McGrath won the 125 West supercross title in 1991 and 1992. At the start of the 2001 season, McGrath won 2 of the first 3 rounds. However, Team Kawasaki's
Ricky Carmichael went on to win every race from there on out; dethroning McGrath as Supercross champion and matching his 1996 win record of 13 consecutive main event victories. McGrath returned in 2002 to take a shot at regaining his crown, but chronic arm pump and
compartment syndrome limited his efforts, but still managing a 3rd place overall in the series behind Carmichael and Yamaha's
David Vuillemin. In 2003, McGrath signed with
KTM; however, a pre-season crash led McGrath to reconsider his future in racing, ultimately leading to his decision to retire just before the start of the 2003 Supercross season. He did a farewell tour with KTM to show his appreciation and sign autographs for fans. In 2005, McGrath came out of retirement to race a limited schedule on the supercross circuit. He rejoined forces with his former Team Honda squad and has recently proven to be at a competitive level and speed that has not been seen from McGrath since the 2001 season. At the age of 34, he placed regularly in the top 5 positions. In the same year, Jeremy also raced
Supermoto in the
X-Games and placed 2nd to take home the silver medal. McGrath switched motorcycles from his trademark Honda CR250R 2-stroke to a Honda CRF450R 4-stroke at Round 3 of the 2006 Supercross season. In keeping with his partial schedule, McGrath withdrew from the series after Round Six, after earning multiple top 5 finishes, and running as high as fourth in the point standings. Jeremy competed in the 2006
Summer X Games; earning a 2nd in Step-Up and 7th in Supermoto. He announced plans for the McGrath Invitational; an off-season supercross race with an innovative track and rider
purse. McGrath announced that the 2006 Invitational would be the final professional Supercross race of his career. He holds the third best record for most combined AMA supercross and motocross victories with 102 career wins; only Ricky Carmichael and
James Stewart have won more. In the 2010s, he transitioned into
off-road truck racing, competing in the Pro 2 division of the
Lucas Oil Off Road Racing Series (LOORRS). In 2017, McGrath won the Pro 2 class championship in the series. McGrath has occasionally raced in
off-road races in the late 2000s. He has finished in the Top 10 in several PRO-2 races. In 2017, he won the championship in the Pro 2 division of the
Lucas Oil Off Road Racing Series. Since 2016, McGrath has partnered with Kawasaki to host a weekly video series, entitled "Science of Supercross", which is hosted on
YouTube and featured as a portion of the live broadcast of Supercross when the series is active. Occasionally, McGrath has guest-commentated Supercross races as well.
Other business ventures Jeremy McGrath Supercross A video game series based on McGrath's motocross career, titled
Jeremy McGrath Supercross, debuted in 1998. In early installments, McGrath was the primary character, but later games introduced customizable riders while still featuring him in various gameplay modes as a competitor and mentor, offering players insights into motocross racing strategies.
Pole Position Raceway In September 2005, McGrath teamed up with long-time friends Ken Faught and Jason Williams to create a state-of-the-art indoor
go-kart track called Pole Position Raceway. The track uses environmentally friendly electric karts that produce 20-horsepower.
ARMA Sport Inc. In February 2020, McGrath co-founded Arma Sport Inc. along with Scott Sepkovic, founder of Spy Optics and CrownAMG, and fellow motocross rider Nick Wey. The company produces a line of
sports nutrition products. ==Career results ==
