Yamaha’s Bold Leap to V4 Development Marks a Revolutionary Shift in MotoGP Strategy

Speculation about Yamaha's potential significant change to a V4 engine in MotoGP suggests it could improve its standings. However, it's the change in mindset that will likely provide the greatest advantage.

The announcement that Repsol is set to conclude its three-decade-long title sponsorship with Honda's factory team at the end of the 2024 season marks a significant indicator of the changing dynamics within MotoGP throughout the 2020s.

The once dominant force, Repsol, stepping aside occurs as Honda faces arguably its toughest period in the premier class. This downturn is especially pronounced considering that just five years earlier, it had secured a world championship in what was one of the most commanding performances ever seen from a rider, thanks to Marc Marquez, underscoring the severe decline the Japanese manufacturers have experienced.

Honda's only victory last year, achieved by Alex Rins at the Circuit of the Americas, stands as the most recent triumph for the now-reduced duo of Japanese motorcycle manufacturers, following Suzuki's unexpected departure at the close of 2022. Yamaha has not celebrated a win since 2022, highlighting a shift in dominance away from the Japanese firms towards their European counterparts.

Since the conclusion of 2022, Ducati has shown unparalleled supremacy in the racing world. The team secured victories in all but three of the grand prix events in 2023, leading Francesco Bagnaia to his second world championship title. Apart from Aprilia's victory at COTA this year, Ducati has consistently maintained its position at the forefront, without being surpassed for the top spot on the podium.

At the same time, Honda and Yamaha are making the most of the allowances granted to them at the previous year's end, striving to advance their positions through development.

Up to this point, both have struggled to achieve a podium finish (Quartararo briefly held third position at the Jerez sprint due to a penalty, but his placement was largely due to numerous accidents ahead of him). This season, Yamaha's average distance from the leader at the finish of each grand prix has been 25.168 seconds, and for Honda, the situation is somewhat more dire, with an average lag of 33.229 seconds.

In 2024, Yamaha has outperformed Honda to some extent. The company hailing from Iwata has managed to secure positions within the top 10 on four occasions during Sunday races. In contrast, Honda has not yet managed to achieve this feat, despite having an additional two riders compared to Yamaha.

Starting next year, Yamaha's strategy will shift as it collaborates with Pramac Racing to include Miguel Oliveira and Jack Miller in their team. Choosing a seasoned duo for Paolo Campinoti's team, Yamaha aims to join forces with Quartararo and Alex Rins at the factory level to hasten the progress of their motorcycle for the 2025 season.

Yamaha and Honda have both been taking advantage of the concession perks, allowing them to conduct in-season tests with their racing riders. However, it's Yamaha that appears to be producing a greater number of components to subsequently introduce at Grand Prix events.

Despite not leading to significant advancements, a series of recent improvements in engine, aerodynamics, and chassis technology have offered modest enhancements upon their implementation. Honda, which appeared to have made considerable progress with the RC213V during last year's Valencia test, soon realized that its 2024 prototype fell short of expectations just after several races.

Since that time, it has been in a constant cycle of pursuit, with the anticipated significant redesign of the motorcycle for the previous Monday's Misano test appearing not to come to fruition.

"Mir expressed disappointment following the Misano test, indicating it didn't meet his expectations," he commented, reflecting on the lackluster advancements with the RC213V. While Luca Marini had high praise for the new aerodynamic fairing, it appeared to be the sole highlight.

At the same time, Yamaha didn't introduce any new developments since they had already assessed numerous components during private testing sessions. Quartararo and Rins expressed satisfaction with the progress in the chassis design. Additionally, Rins had the opportunity to compete with a prototype engine planned for 2025 at the Aragon race, where he secured his best result of the season by finishing ninth. This engine was not used for the San Marino Grand Prix, yet it provided Rins with an improvement in his race speed, enhancing it by approximately 0.5 to 0.7 seconds.

The reasons behind the engine not being used again at Misano, as well as its future appearances, remain uncertain. This uncertainty was highlighted by a notable remark made during the Misano test, especially in light of subsequent reports from es.motorsport.com. These reports suggested that Yamaha was significantly progressing in the development of its inaugural V4 engine for the contemporary era.

Yamaha stands out as the sole manufacturer employing a four-cylinder engine in a straight-line configuration, in contrast to its competitors who favor V4 engines. This approach has been a consistent strategy for Yamaha throughout the current four-stroke era, a stance it has maintained even as its performance has waned in recent times.

Simplified, an inline-four engine doesn't pack as much punch as a V4 engine. However, its slimmer profile offers greater versatility in the design of the motorcycle's frame, leading to bikes that typically handle more agilely. This trait was also evident in the Suzuki when it competed in MotoGP, utilizing the inline-four configuration.

This season, Yamaha's competitors, especially Quartararo, have voiced concerns that the M1 no longer performs as it once did. Despite traditionally lagging behind in power compared to its competitors, Yamaha managed to stay in the race through superior handling and grip. However, with this advantage no longer apparent, rethinking the engine strategy is starting to look like a viable option.

The transition to a V4 engine is being spearheaded by Luca Marmorini, who has been advising Yamaha on its engines as a consultant since 2022. With a background as an engine director for both Toyota and Ferrari in Formula 1, Marmorini has been instrumental in enhancing the power of the M1 as per the demand. However, this increase in power hasn't significantly improved the M1's performance, particularly in areas like rear grip and cornering.

This decision aligns with MotoGP's transition to 850cc engines starting in 2027. Ideally, if Yamaha manages to equip its motorcycle with a V4 engine by 2025 and effectively develop it, this could enhance its performance once the 2027 rules are implemented. Additionally, an anticipated freeze on engine development for the remainder of the current regulatory period could benefit Yamaha, assuming it doesn't face restrictions due to better performance outcomes.

If Yamaha transitions to a V4 engine configuration next season, it won't immediately propel them up the rankings. However, this shift in strategy indicates a real change in the traditionally rigid approach often attributed to both Yamaha and Honda's decline in MotoGP standings.

Bringing Marmorini on board as an advisor, along with the recruitment of Max Bartolini from Ducati to serve as Yamaha's head of technology, signaled a move in this direction. However, such steps would have been futile without decisive support from the decision-makers in Iwata. In a contrasting situation, Honda had engaged Kalex to develop a chassis for them the previous year, which was soon rejected by its riders, leading to the termination of their relationship with the company.

Moving away from its traditional engine design will allow Yamaha to venture into previously unexplored territories, potentially enhancing motorcycle innovation. It's evident that Yamaha has acknowledged that sticking to its old strategies won't outdo Ducati. Moreover, it understands that facing a few setbacks is a part of the journey towards success as it ventures into new areas.

Acknowledging this is the initial significant move towards returning to the spotlight…
