By late August 2026, the transition of Jack Miller from MotoGP to Yamaha’s WorldSBK program moved from speculation toward official confirmation. Yamaha Motor Co. and Pramac Racing announced that Miller’s partnership with the MotoGP project will conclude at the end of the 2026 season. Following the Aragon Grand Prix, Miller provided technical insights into the development of Yamaha’s new V4 engine. While noting the bike’s effectiveness in corners, he highlighted a critical deficit in top speed, reporting a gap of up to 10 km/h on straights compared to competitors like KTM. Miller described the situation as having his ‘hands tied behind his back,’ as tire protection strategies required for long-distance competitiveness further limited his ability to compensate for the lack of power. Despite these constraints, Miller finished 10th in the Sprint and 11th in the Grand Prix, notably outperforming teammate Fabio Quartararo. In September 2026, it was confirmed that Miller will transition to the World Superbike Championship (WorldSBK), joining the Pata Maxus Yamaha factory team for the 2027 and 2028 seasons. He will replace Xavi Vierge and partner with Andrea Locatelli. This move follows Miller’s demonstration of speed on the Yamaha R1 during the Suzuka 8 Hours endurance races. To fill the vacancy in MotoGP, Yamaha announced that Moto2 rider Izan Guevara will join the Prima Pramac Yamaha team for 2027, partnering with Toprak Razgatlioglu as part of a strategy to invest in younger talent ahead of the 2027 technical regulation changes. During the Austrian Grand Prix in late September, Miller faced further difficulties. After initial strength in the early laps, extreme rear tire degradation caused his pace to plummet, with lap times eventually exceeding those of Harley-Davidson Baggers on the same circuit.
