Fabio Di Giannantonio hails from Rome, Italy and ended the 2013 European Moto3™ Championship in ninth. For 2014 he began to focus on the Red Bull Rookies Cup, ending the year in eighth with a best finish of second at Brno. In 2015 he emerged as a title contender, taking two wins and four second place finishes to end the year in second. This saw him quickly snapped up by the Gresini team, racing the final 2015 round for them in Valencia before joining the team full time in 2016. After fighting to be Rookie of the Year and taking three podiums, Di Giannantonio stayed with Del Conca Gresini Racing Team Moto3™ for 2017 and took five podiums to take P5 overall. He remained with the outfit in 2018, and managed to secure second in the lightweight class Championship after claiming his first two Grand Prix race wins.

A step up to the Moto2™ class with Speed Up Racing was the Italian’s next chapter, and it was an impressive year. Six top tens, coupled with two podiums in Brno and Misano, saw Di Giannantonio claim P9 overall and the Moto2™ Rookie of the Year. Chasing a first intermediate class victory in 2020, the Italian could only muster two podium finishes while he cruelly crashed out in the Valencia GP as he searched for that elusive victory. 2021 was a year of change as Di Giannantonio moved to Federal Oil Gresini Moto2 and a Kalex bike. Better fortunes came his way as he clinched that all-important Grand Prix win in Jerez. Three other podiums were enough to earn the Italian a dream move to MotoGP™ in 2022.

The highlight of Diggia's rookie campaign was pole position at his home Grand Prix at Mugello, and he remained with Gresini Racing in 2023, but teamed up with World Championship winning crew chief Frankie Carchedi. Pre-summer brought a best finish of P8, but the Italian raised his game in the final races of the season. A debut podium came in Australia before a first MotoGP™ win was pocketed in Qatar. A late penalty denied Di Giannantonio a podium in Valencia too, but it was his incredible late-season form that saw him bag a ride alongside Bezzecchi in the VR46 set-up, having lost his Gresini seat to Marc Marquez. Now, can this form continue in 2024?
