The final place on the 2025 MotoGP grid has been officially confirmed with Jack Miller completing the new Pramac Yamaha line-up alongside Miguel Oliveira.

The Australian thus returns to the team he raced for, with Ducati machinery, from 2018 to 2020.

Miller was then promoted to the factory Ducati team, winning three races, before joining Red Bull KTM at the start of last year.

Like Oliveira, Miller has signed directly with Yamaha and ‘can count on having a Factory 2025 YZR-M1.. as well as full Factory support’. Unlike the Portuguese, who signed for two years, Miller appears to have only a one-year deal.

“We are happy to announce that Jack is joining Prima Pramac Racing’s line-up, and we warmly welcome him to the Yamaha MotoGP group,” said Yamaha Racing managing director Lin Jarvis.

“With 10 years of experience in the MotoGP class with three different manufacturers, Jack will be a valuable asset for Yamaha. His speed, knowledge, work ethic, and team spirit will be invaluable to our project as we plan to improve the performance of the M1 in 2025 and beyond.

“Yamaha will be supporting him in every way they can.”

Rookie Pedro Acosta will take over Miller’s KTM seat for 2025 but the 29-year-old – who leapt straight to MotoGP from Moto3 in 2015 and took a shock debut win for Marc VDS Honda the following year – was surprised to lose out on a Tech3 seat.

Miller later admitted his chances of staying in MotoGP were looking bleak and that the phone was not ringing, before suddenly moving into pole position for the Pramac Yamaha ride.

Miller took a podium in only his fourth KTM grand prix, at Jerez last year, then a second Sprint podium in German, but has been absent from the rostrum ever since.

The former Moto3 title runner-up is 15th in the riders’ standing heading into this weekend’s Emilia Romagna round.

Pramac, leading the MotoGP standings with Jorge Martin on Ducati machinery, will run factory-spec YZR-M1s next year equal to the Monster Yamaha team.
