There is only one seat still up for grabs on the 2024 MotoGP World Championship grid and things are filling up nicely over in the supporting Moto2classes.

With five rounds of both series' still to come in a tightly-packed end-of-season schedule, Moto2 has filled 24 of an available 30 seats with ten teams having announced both of its riders..

So, who is signed up, who is out and who is still refreshing their emails every five minutes...?

2024 Moto2 World Championship

With just one rider heading on up to Moto2 in the form of champion-elect Pedro Acosta, the 2024 Moto2 World Championship grid will bear a similar look to this year's line-up, albeit with a few familiar faces in unfamiliar places.

As it stands, Tony Arbolino looks set to be the highest-placed rider from 2023 returning for 2024, the Italian having re-signed with Marc VDS Racing, while Jake Dixon behind him in third overall at this time is also sticking with what he knows on the GasGas Aspar Kalex.

There are changes elsewhere though with Aron Canet switching from Pons Racing - which exits Moto2 - in favour of a move to Fantic Racing, while Filip Salad swaps Gresini for Marc VDS for his third season.

Champions in 2021, 2022 and most likely again in 2023, Red Bull KTM Ajo's high expectations will be handled by Celestino Vietti, who leaves the VR46 Academy fold in favour of shacking up with KTM instead, and rookie Deniz Oncu, who steps up from Moto3.

Other moves taking place within Moto2 include Joe Roberts, who returns to American Racing to team up with Rory Skinner, who will look to make a step forward from what has been a tough maiden campaign in 2023, and Albert Arenas, who lands at Gresini Racing.

In addition to Skinner, those also staying put in 2024 include Darryn Binder (Husqvarna Intact GP), Dennis Foggia (Italtrans), Somkiat Chantra (IDEMITSU Honda Team Asia) and Bo Bendsneyder (SAG Team).

Each will get a new rookie team-mate too with Moto2 European title contender Senna Agius joining Binder, Diogo Moreira rising from Moto3 to join Italtrans, Mario Aji coming in alongside Chantra and Moto3 leader Jaume Masia penning a deal with SAG Team. Ayumu Sasaki will also graduate from Moto3, joining the Correos Pageo Yamaha VR46 team.

With Pons Racing ending its long-association with Grand Prix competition at the conclusion of the season, its entry will be assumed by the Teo Martin-run MT Helmets - MSI outfit, which has signed the experienced Ai Ogura and 2022 Moto3 runner-up Sergio Garcia for its inaugural campaign in the intermediate class.

Just the two teams will boast unchanged rider line-ups for 2024 in the shape of GasGas Aspar, where Izan Guevara gets a second season alongside Dixon, while Racing GP will retain Barry Baltus and Zonta van den Goorbergh.

Those without a ride include Alonso Lopez, though his seat alongside Fermín Aldeguer at SpeedUp remains unfilled for now, American Racing's standout stand-in Marcos Ramírez and the bad boy of Moto2 right now, Jeremy Alcoba.
