[1][2] Roberts competes in the FIM Moto2 World Championship with OnlyFans American Racing Team aboard a Kalex chassis bike.

He competed successfully for two seasons in the USGPRU (United States Grand Prix Racer's Union) finishing 3rd in points in 125GP in 2010.

At the end of 2010 he was invited to the Red Bull MotoGP Rookies Cup try-outs for the 2011 season and was one of 12 selected from 100 applicants.

He would qualify for pole again in the fourth round and finished the race in third, becoming the first American driver on the podium since Spies at the 2011 Valencian Community motorcycle Grand Prix and the first in mid class since John Kocinski at the 1993 Dutch TT.

Roberts was offered not only deals with multiple front running teams on the Moto2 grid but was even offered a MotoGP ride with Aprilia to partner Aleix Espargaro in 2021, a move that was endorsed not only by Roberts manager and American Racing team principal Eitan Butbul but also his mentor John Hopkins and was even endorsed by Espargaro himself.

[20] Roberts suffered a broken collarbone at Misano on October 22, 2021, and underwent surgery the following Tuesday, forcing him to miss the last two rounds of the 2021 season.

The Malibu rider returns to the team that led him to make his debut in the world championship, now with content subscription service OnlyFans as a big sponsor.
