Jack Miller to Leave Pramac Yamaha at End of 2026 MotoGP Season

Jack Miller will leave Prima Pramac Yamaha at the end of the 2026 MotoGP season, bringing his latest spell with the Italian outfit and Yamaha’s premier-class project to an end.

Yamaha confirmed on Thursday that its collaboration with the Australian rider would conclude after this season. The manufacturer credited Miller with playing an important role in the development of its MotoGP programme, particularly during a period of significant technical change.

Miller returned to Pramac in 2025 after previously racing for the team between 2018 and 2020, but this time the partnership came under a different banner. Pramac switched from Ducati to Yamaha for the 2025 season, making Miller one of the experienced riders helping the manufacturer establish its new satellite operation.

His departure is part of a broader reshaping of the Pramac Yamaha line-up ahead of 2027. Spanish rider Izan Guevara has been confirmed as Miller's replacement, moving up from Moto2 after previously winning the Moto3 world championship in 2022. The 22-year-old currently sits near the top of the Moto2 standings and will make his MotoGP debut as the championship enters a major technical reset.

The timing is significant. MotoGP will introduce a new generation of motorcycles in 2027, including smaller 850cc engines, while the championship is also preparing for other technical changes. Yamaha's decision to promote younger talent signals its intention to build around riders it sees as part of its longer-term future rather than simply preserving experience in the satellite squad.

Miller's immediate future remains less certain in MotoGP. Reports have increasingly linked the 31-year-old Australian with a move to the World Superbike Championship with Yamaha, although that next step has not been presented as a fully confirmed racing contract. Miller has also indicated that a future MotoGP testing role could remain an option even if he leaves the full-time grid.

The announcement closes another chapter in a long MotoGP career for Miller, who made his premier-class debut in 2015 and has remained a familiar figure on the grid through several changes of manufacturer. His career has included victories with Ducati and periods with Honda, Ducati and KTM before his return to Pramac under Yamaha.

For Pramac, meanwhile, the move represents a clear investment in youth. Guevara will join Turkish rider Toprak Razgatlioglu, who is already contracted with the team through 2027, giving the satellite Yamaha squad a markedly different line-up for the new technical era. Yamaha managing director Paolo Pavesio described Guevara as a rider with the talent and work ethic required for the premier class.

Miller's exit also illustrates how quickly MotoGP's competitive landscape is changing. Riders who have spent years shaping the current generation of bikes are increasingly being replaced by younger prospects as manufacturers plan around the 2027 regulations. For Miller, the remaining races of 2026 now carry an added significance: they represent not only the final stretch of his Pramac Yamaha career, but potentially the closing races of his full-time MotoGP journey.

Whatever comes next, Miller leaves behind a career defined by longevity, adaptability and an ability to remain relevant through several generations of MotoGP machinery. His departure, alongside the arrival of riders such as Guevara, underlines the sport's next transition, one in which established experience is giving way to a new generation just as MotoGP prepares to reinvent its bikes for 2027.
