Álex Márquez’s #73:
Bike Number, Age & Helmet Design Explained
The Gresini Ducati rider has made 73 one of the most recognisable numbers in MotoGP. Why he races it, how old he is, what his helmet design means — and the career behind the AM73 brand.
Álex Márquez’s #73 Explained
Bike number, age, helmet design and the career behind the AM73 brand.
Álex Márquez races with the number 73 — the same number he has carried throughout his grand prix career, from his Moto3 title season through to his current seat at BK8 Gresini Racing in MotoGP. Fans often search for his “car number”; in MotoGP it is a bike number, and 73 has become the core of his AM73 personal brand.
Born on 23 April 1996 in Cervera, Spain, Márquez is 30 years old and a two-time world champion — Moto3 in 2014 and Moto2 in 2019 — with a maiden MotoGP victory at Jerez in 2025 and a career-best 2026 season that included second place at Misano in the first Márquez brothers one-two of the year. Below: the story of the number, the helmet, and the rider.
Álex Márquez’s Bike Number: The Story of #73
Álex Márquez’s race number is 73. He has used it since his early grand prix career in the lightweight classes, carried it through his Moto3 and Moto2 world titles, and brought it with him to MotoGP when he debuted with Honda in 2020. Where his brother Marc’s famous 93 is a nod to his 1993 birth year, Álex simply made 73 his own — building his entire personal brand, AM73, around it.
The number is everywhere in his racing identity: on the front and tail of the Gresini Ducati, across his leathers, on his merchandise, and — most visibly of all — as the centrepiece of his helmet design. In an era where riders are brands, AM73 is one of the paddock’s most complete.
MotoGP uses a permanent career number system: a rider picks a number early in their grand prix career and keeps it for as long as they race, which is why 73 has followed Márquez through three classes and four teams. The one exception is the number 1 plate, reserved for the reigning world champion — his brother Marc has carried it as defending champion this season. Numbers become so tied to identity that retired legends’ numbers are sometimes withdrawn from use entirely. For more on how the sport is structured, see how racing championships are scored.
Marc has 93. Álex has 73. In the Márquez household, the numbers are as much a part of the family as the surname.
How Old Is Álex Márquez? Age & Career Timeline
Álex Márquez is 30 years old, born on 23 April 1996 in Cervera, Catalonia — the same small Spanish town that produced his older brother. He is the younger of the two by three years, and his career has followed a path that is unusual among champions: he won world titles in both junior classes, then had to rebuild his MotoGP career after a difficult factory Honda debut before emerging as a race winner on Ducati machinery.
Álex Márquez’s Helmet Design Explained
Márquez’s helmet is one of the most recognisable in the MotoGP paddock, and it is built around three constants that have survived every team change of his career.
Like most top riders, Márquez runs special-edition designs for the calendar’s biggest weekends — home races in Spain carry extra personal touches, and at Misano in 2026 he raced a special tribute livery honouring Marco Simoncelli, the most emotionally charged design of his season. His long-time personal sponsors, led by Estrella Galicia 0,0, have remained on the helmet through every team change — a visual thread connecting the Moto3 champion of 2014 to the MotoGP race winner of today.
With riders hidden behind leathers and fairings, the helmet is the one piece of a MotoGP rider that is fully theirs — which is why designs become fan phenomena in their own right and why a rider’s number is always the centrepiece. It is the two-wheeled equivalent of a car driver’s pole position trophy: instantly recognisable, endlessly collected.

The arc is one of the better comeback stories in the modern paddock: champion twice over in the junior classes, written off by some after the Honda years, and now a race winner heading to a factory seat. His 2026 form — second at Misano and in the thick of the fight for fourth in the championship — is the strongest of his MotoGP career.
Márquez joins Fabio Di Giannantonio at Red Bull KTM Factory Racing for 2027, replacing Pedro Acosta — who moves the other way to the factory Ducati team. It is one of the defining swaps of the 850cc era’s opening market. Full picture: MotoGP driver market — September 2026.
The Márquez Brothers: Racing’s Most Famous Siblings
Álex is the younger brother of Marc Márquez, the six-time MotoGP world champion and the man currently leading the 2026 standings on countback. They grew up racing each other in Cervera, won world titles in the same paddock, and have spent the 2026 season as direct rivals — Marc at the factory Ducati team, Álex at Gresini.
Their defining moment of the season came at Misano, where Marc won and Álex finished second — the first Márquez brothers one-two of 2026 — with Álex racing a tribute livery for Marco Simoncelli and recovering from a disastrous Saturday to almost steal the win in the closing laps. It was the second time in history the brothers had shared a premier-class podium lockout, and it underlined how far Álex has come from the years when he was described primarily as “Marc’s brother.”
The brothers’ 2026 has had its flashpoints too — including the much-discussed incident covered in our report on Álex Márquez and Johann Zarco’s crash, one of the season’s most debated moments. At this level, even family comes second to the championship.
What makes the rivalry work is that it is real. Marc leads the standings on countback; Álex is fighting for fourth and took second off his brother at Misano on pure pace. With Álex moving to KTM and Marc partnered by Acosta at Ducati in 2027, the brothers will spend next season on different machinery for the first time in years — on tracks where the slipstream can put them wheel to wheel at 350 km/h.
Frequently Asked Questions
More than a number
The 73 started as a race number and became an identity. Álex Márquez has carried it from an 18-year-old Moto3 champion to a 30-year-old MotoGP race winner — through a factory Honda dream that turned difficult, a Ducati rebuild that restored him, and a Misano afternoon where he finished one place behind his brother and ahead of everyone else.
The blue helmet with the big 73 will look different in KTM orange next season, but the essentials will not change: the number, the monogram, and a rider who has quietly become one of the most complete on the grid.
We update this profile as his 2026 season concludes and the 2027 KTM chapter begins. For the championship picture he is racing in, see our MotoGP coverage linked above.
