Even if Yamaha did want to stick with its inline-four engine, MotoGP’s new rules are set to force it towards the V4
Yamaha, currently the only MotoGP manufacturer with an inline four engine, is developing a new V4 powerplant to match the speed and cornering capabilities of its competitors. The switch to a V4 engine may become mandatory under the new rules set to be introduced in 2027. Despite being the last V4 outlier since Suzuki’s departure in 2023, Yamaha has maintained its unique configuration due to smoother power delivery and better cornering abilities. The transition to a V4 engine could happen as early as the 2025 season under Yamaha’s concession status but has been delayed by the extensive engineering required to adapt to the new shape. The move towards V4 engines is not solely due to engine regulations but also influenced by upcoming aerodynamic restrictions that will limit the width of devices to reduce costs and improve overtaking opportunities. Yamaha’s potential switch to a V4 engine aims to ensure compliance with the evolving rules and maintain a competitive edge in MotoGP.
