Australian MotoGP veteran Jack Miller will leave Prima Pramac Yamaha at the conclusion of the 2026 MotoGP season, ending a two-chapter, five-season association with the Pramac outfit. Yamaha Racing confirmed the split ahead of the Aragon Grand Prix, with the departure also expected to mark the end of Miller's premier-class career.

Official Confirmation and Team Reaction

Yamaha Motor Racing managing director Paolo Pavesio paid tribute to the Australian's technical contributions. 'Jack joined Yamaha at an important stage of our MotoGP project and immediately became a valuable contributor. His technical understanding, openness to feedback, and relentless commitment helped us move forward in several areas,' Pavesio said in a statement.

Pramac Racing team principal Paolo Campinoti was equally effusive. 'Some riders pass through a team, while others leave a lasting mark on its history, and Jack certainly belongs to the second group,' Campinoti said. He added: 'We are naturally sorry that our journey together is coming to an end, but this is part of the decisions that have to be made in our sport. We wish Jack and his family every success for whatever comes next. The door will always be open for him, because once you're part of the Prima Pramac family, you'll always be part of it.'

Miller's MotoGP Career at a Glance

Miller made his MotoGP premier-class debut in 2015 and went on to win four races across multiple manufacturers — Honda, Ducati, KTM, and Yamaha. He joined Prima Pramac Yamaha in 2025 specifically to support the launch of Yamaha's revamped MotoGP project, providing crucial machine insights and technical feedback alongside his racing duties.

His best result with the outfit was a fifth-place finish at the USA GP. He also competed in the 46th edition of the Suzuka 8 Hours, demonstrating his versatility beyond the premier class.

What Comes Next for Miller

According to Fox Sports, Miller is reportedly set to sign a deal with Yamaha in the World Superbike series for 2027, suggesting his professional racing career will continue in a different championship. This would represent a common transition path for MotoGP veterans seeking competitive opportunities at the highest level of production-based racing.

Significance of the Split

Miller's exit closes a chapter in Yamaha's rebuilding effort in MotoGP. He arrived at a critical juncture when the Japanese manufacturer was restructuring its satellite programme through Pramac, and his experience — spanning four manufacturers — made him a valuable development asset. Notably, this is the second high-profile rider departure from the Yamaha stable in recent seasons, underscoring the competitive pressures reshaping the grid heading into 2027.
