The MotoGP community is buzzing with the latest developments at Yamaha, where the long-awaited V4 engine project has captured widespread attention. Yamaha, historically associated with its reliable YZR-M1 inline-four, is venturing into uncharted territory by testing a V4 engine for possible use in the 2025 season. However, news from Jerez has left fans and analysts in shock: the initial results of the V4 engine tests have not lived up to expectations.

Since 2002, Yamaha has dominated MotoGP with its inline-four engine, taking eight riders’ titles and five manufacturers’ titles. However, as MotoGP technology has evolved, rivals with V4 engines have begun to outperform Yamaha. The decision to develop a V4 engine reflects Yamaha’s intention to remain competitive, especially in light of new regulations and the evolutionary dynamics of tire technology.

Michelin’s narrow performance window in the rear tire design has made this transition even more necessary. V4 engines, known for their superior torque and stop-and-go cornering ability, seem better suited to exploit the characteristics of these tires. In contrast, inline-fours rely heavily on front tire grip to achieve their characteristic speed through sweeping corners.

Yamaha team principal Lynn Jarvis addressed the mixed reactions to the Jerez test. Speaking frankly, he acknowledged the difficulties but remained optimistic about the project. “This is not a project born in panic,” Jarvis stressed. “We have been planning and researching for years. The V4 engine represents the next step in Yamaha’s evolution in MotoGP, but we will proceed with caution to determine whether it truly exceeds the potential of our inline-four.”

Jarvis revealed that the V4 engine is still in the early stages of on-track testing, having already undergone rigorous endurance testing at the factory. Despite its disappointing performance at Jerez, Yamaha intends to refine the engine ahead of its planned debut at the Sepang pre-season test in February 2025.

The move to a V4 configuration represents a significant step forward for Yamaha, requiring considerable financial and technical resources. With the YZR-M1 inline-four engine still in development, Yamaha faces the dual challenge of perfecting two engine configurations at the same time. The stakes are high, but Jarvis believes the investment is justified, given that inline-four engines show limitations at high rpm, while rivals with V4 engines currently dominate the MotoGP landscape.

The project also aligns with the 2027 MotoGP regulations, which could further standardize engine configurations. Yamaha’s adaptability today could prove to be an advantage in the future, ensuring the team remains at the forefront of the sport.

While some fans are excited by Yamaha’s willingness to innovate, others fear the brand could lose its identity or scatter its resources. Analysts point to the difficulties of abandoning an established formula to adapt to the growing competitive demands of MotoGP. The shock of the Jerez test is a reminder of the risks inherent in such a bold engineering feat.

Despite the obstacles, Yamaha remains steadfast in its vision. The development of the V4 engine is not just about competitiveness: it is about shaping the future of MotoGP technology. Whether this gamble will pay off, only time will tell. But one thing is for sure: Yamaha’s journey with the V4 engine will be one of the most followed stories in the 2024 MotoGP season and beyond.

As Jarvis said: “We are building for the future, and that future starts now.”
