Jack Miller’s spell as a Yamaha MotoGP rider is over at the end of this season. The Australian’s exit was confirmed by Yamaha and Prima Pramac in releases at Aragon, closing his second stint with the Italian outfit after two seasons on Yamaha machinery.
Neither statement named his 2027 destination, and Miller himself offered only a note of intent.
“I still believe I have more to offer and more to achieve, and I’ll take that motivation with me into whatever comes next.”
He had already flagged the outcome weeks earlier. Speaking to Motorsport.com on 7 August, he said he was “not naive” about his position and expected a decision within weeks.

Pavesio thanks a ‘valuable contributor’
Yamaha Motor Racing managing director Paolo Pavesio was warm rather than valedictory, framing Miller as a rider who had shaped the manufacturer’s development direction.
“Jack joined Yamaha at an important stage of our MotoGP project and immediately became a valuable contributor,” Pavesio said in the Yamaha release.
“His technical understanding, openness with feedback, and relentless commitment helped us move forward in several areas.”
Miller had arrived at Pramac for 2025 after two seasons at factory KTM, and Yamaha leaned on him as much for his engineering feedback as his race craft.
The WorldSBK move Miller wants
The link that will not go away is a factory Yamaha R1 seat in the World Superbike Championship. No deal has been announced, but Miller has made no secret of the appeal.
“For sure, I’m looking forward to hopefully heading over there and doing something special over on that side of the field,” he told Crash.net on 6 August, when asked whether WorldSBK appealed to him.
He also pointed to his history with the manufacturer as a reason a switch would be a natural fit, having ridden the Yamaha R1 at the Suzuka 8 Hours in 2025 and 2026 alongside Katsuyuki Nakasuga and Andrea Locatelli, finishing runner-up on both occasions.
Izan Guevara steps up at Pramac
The vacancy Miller leaves has already been filled. Izan Guevara is promoted from Moto2 to take the Prima Pramac seat for 2027, lining up alongside Toprak Razgatlioglu, who continues in the team’s other saddle.
