Yamaha Confirms Switch to V4 Engine from 2026 MotoGP Season

November 17, 2025

November 17, 2025—Yamaha is delighted to officially announce the transition of its YZR-M1 from the iconic inline-four engine to the V4 configuration from the 2026 MotoGP season.

Yamaha Motor Co., Ltd. confirms that the YZR-M1 machines will be powered by the V4 engine starting from the 2026 MotoGP season. This decision aligns with Yamaha's earlier stated intentions to transition, underlining the continuity and transparency of Yamaha's engine development strategy.

The inline-four has been a cornerstone of Yamaha's racing identity for decades, powering legendary riders such as Valentino Rossi, Jorge Lorenzo, and Fabio Quartararo. Its unique combination of agility and smooth power delivery led to countless successes: the inline-four competed in 429 Grands Prix, won 125 races, stood on 352 podiums, and helped Yamaha claim 8 Riders Title, 7 Team Titles, 5 Manufacturer Titles and 5 MotoGP Triple Crowns.

However, as MotoGP evolves, Yamaha embraces the challenge of adapting to new technical demands while preserving its DNA. The move to the V4 marks a significant milestone in Yamaha's pursuit of performance and innovation. The new configuration is expected to deliver improved acceleration, better handling under braking, and greater adaptability to the most recent tyres and aerodynamics requirements. The quick development process over the course of the 2025 season reflects Yamaha's commitment to be at the forefront of MotoGP technology while honouring its heritage.

The Grand Prix of the Valencian Community marked the final race and the closing chapter for Yamaha's iconic inline-four engine in MotoGP. Stepping into a new era, all 2026 Yamaha MotoGP riders will ride with the V4 engine during Tuesday's Valencia Test, signalling the start of an exciting new beginning for Yamaha and its fans worldwide.

"The inline-four has been at the heart of Yamaha's philosophy for decades. It delivered unforgettable victories and shaped our reputation for precision and control. We are proud of what this engine has achieved and of the riders who made history with it, as they all together have shaped our racing heritage. However, MotoGP is constantly evolving, and we must evolve with it. The V4 represents a new chapter for Yamaha, one that combines our 'Spirit of Challenge' with our racing DNA and the technical solutions required to fight at the top. Our goal remains the same: to give our riders the best possible motorcycle to win and to bring fans all around the world the feeling of 'Kando*'."

*Kando is a Japanese word to express the deep satisfaction and excitement you get when encountering something of exceptional value, quality, and performance.

“We want to extend our heartfelt gratitude to Manzi for clinching the title. Winning in the debut season of the YZF-R9, a machine that represents a milestone for Yamaha, was a significant achievement, proving the bike’s outstanding potential.
Manzi’s strong determination and fearless riding in decisive moments, often battling fiercely with young talents like Öncü, led to multiple victories and inspired Yamaha riders across the board. His performance set a new benchmark and ignited everyone’s competitive spirit.
The YZF-R9 has also shown that its exceptional capabilities can accelerate the growth of young riders and elevate them to the next stage of their careers. As we look ahead to next season, we are committed to developing riders who will follow in Manzi’s footsteps, so stay tuned!”
