Jack Miller's time with Yamaha will come to an end after the 2026 MotoGP season, bringing another major chapter of the Australian rider's career closer to its conclusion.
Yamaha and Prima Pramac Yamaha have confirmed that Miller will leave the project at the end of the year, ending a two-season partnership that began when Pramac switched from Ducati to Yamaha in 2025.
Miller joined Yamaha at an important stage of the manufacturer's MotoGP rebuild and played a key role in developing the YZR-M1. His experience and technical feedback were regarded as valuable to the project, particularly as Yamaha worked through a difficult period while preparing for the next generation of MotoGP machinery.
The Australian also represented Yamaha outside MotoGP, competing in the Suzuka 8 Hours in both 2025 and 2026. His contribution helped strengthen his relationship with the wider Yamaha racing organisation.
However, Miller's future in MotoGP had already become increasingly uncertain. The 31-year-old has been searching for a competitive seat after struggling to achieve the results he wanted during his recent seasons with KTM and Yamaha.
Miller returned to Pramac in 2025 after spending two seasons with KTM. His comeback came with a major change, as Pramac had moved from Ducati to Yamaha following its long partnership with the Italian manufacturer.
Despite his experience, Miller has found it difficult to regularly challenge near the front. His last MotoGP victory came with Ducati in 2022, while his premier-class career currently stands at four race wins and 23 podium finishes.
With the 2027 MotoGP grid rapidly taking shape ahead of the sport's new 850cc regulations, opportunities for experienced riders are becoming increasingly limited.
Miller's departure also opens the door for younger talent at Pramac Yamaha. Spanish rider Izan Guevara has been confirmed as his replacement for 2027, with the former Moto3 world champion stepping up from Moto2 to the premier class.
For Miller, the next step remains unclear. He has previously indicated that he would like to continue racing and has not ruled out a move to WorldSBK. A switch to the production-based championship could provide him with another opportunity to remain competitive at the highest level.
Yamaha team boss Paolo Pavesio praised Miller's technical understanding, commitment and contribution to the manufacturer's development programme, while Pramac team principal Paolo Campinoti also described the decision to part ways as a difficult one.
Miller, meanwhile, has made it clear that he intends to remain focused on finishing the 2026 season strongly before turning his attention to the next chapter of his career.
After more than a decade in the premier class, the Australian now faces an important decision about what comes next. Whether he remains in the MotoGP paddock or begins a new challenge in WorldSBK, his departure marks the end of another significant chapter in a career that has included victories with Honda and Ducati, as well as more than 20 premier-class podiums.
