[4] Another of McGrath's nicknames, "Showtime," is partly derived from his iconic "nac-nac" move, which helped to spawn what would become known as freestyle motocross.

However, McGrath's popularity transcended the world of motorcycles, taking small roles in the movies Charlie's Angels: Full Throttle[5] and Motocrossed, appearing on The Tonight Show with Jay Leno,[6] licensing a video game series named after him,[7] and featuring in several other offroad racing-related video game titles.

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.

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.

He announced plans for the McGrath Invitational; an off-season supercross race with an innovative track and rider purse.

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.

[4]In April 2007, McGrath announced he had signed a driver development contract with the NASCAR team JR Motorsports, with Monster Energy Drink as his prime sponsor.

[15] 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.

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.

[16] 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.
