Jack Miller explains why Yamaha has gone “all in” on its new V4 MotoGP project for 2026.
Jack Miller believes that Michelin’s rear tire evolution was the key factor in favoring V4 engines in MotoGP’s technical balance. Yamaha, after using an Inline-powered M1 and winning multiple riders’ titles, will switch to a V4 engine in 2026 to align with its competitors. Miller emphasized the crucial role of the rear tire, stating that its development significantly impacts bike performance. The narrow working window of the rear tire demands precise handling for optimal performance in braking, cornering, and acceleration. Miller expressed confidence in Yamaha’s ability to adapt to the V4 engine challenge and believes that their proactive approach is essential for competitiveness in the evolving MotoGP landscape. Additionally, Yamaha faces the task of developing an 850cc/Pirelli-shod machine for the upcoming 2027 regulations, showing their commitment to staying competitive in the sport.
