Yamaha's V4 MotoGP Debut: A Promising Start with Room for Improvement






Yamaha's highly anticipated V4-powered MotoGP machine had its inaugural public appearance at the San Marino Grand Prix, revealing both its strengths and areas needing development. While test rider Augusto Fernandez's performance was notable, showcasing the bike's raw potential, the day also highlighted the ongoing challenges in perfecting the new prototype. The team views this initial outing as a crucial step, with valuable data gathered for future enhancements, signaling a determined effort by Yamaha to reclaim its competitive edge in the sport.
Yamaha's V4 MotoGP Prototype Makes Track Debut at Misano, Revealing Key Insights
On Friday, September 12, 2025, at the Misano World Circuit Marco Simoncelli, Yamaha Factory Racing unveiled its new V4-powered MotoGP bike for its first public track session during the San Marino Grand Prix practice. Spanish test rider Augusto Fernandez was at the helm of the experimental M1. Despite finishing 19th on the leaderboard, his performance provided crucial insights into the bike's capabilities and areas for enhancement.
Early in the first practice session, Fernandez quickly demonstrated the prototype's inherent speed, logging laps within a second of the fastest times. However, a sensor malfunction led to an automatic shutdown, temporarily halting his run. After switching to a backup bike, he returned to the track, ultimately placing 21st, just under a second behind factory rider Fabio Quartararo. Notably, Fernandez was closely matched with Alex Rins, who finished 18th, and trailed Pramac duo Jack Miller and Miguel Oliveira by only half a second, underscoring the bike's promising pace.
During the afternoon session, Fernandez completed an additional 20 laps before a low-speed fall at Turn 2 brought his day to an early close. Nevertheless, he expressed satisfaction with the progress, particularly noting the significant improvements in rear-end grip and management—a long-standing challenge for previous Yamaha models. Quartararo himself acknowledged Fernandez's speed and the V4 bike's potential, emphasizing the need for extensive setup adjustments.
Fernandez highlighted that while some aspects of the previous M1 still hold an advantage, the V4's advancements in rear grip are substantial. He stressed the importance of finding the optimal balance to integrate the front-end performance of the standard bike with the enhanced rear of the V4 prototype. The ability of the team to successfully implement changes based on prior private testing issues further reinforced the positive outlook.
A notable achievement for Fernandez was his competitive one-lap pace, especially considering the constraints of limited tire availability and suboptimal track conditions during previous private tests, which prevented proper time attack simulations. This public debut offered the first true opportunity for such evaluations.
Looking ahead, Yamaha plans to gather more comprehensive data during the upcoming sprint and Sunday's main grand prix event, with particular focus on the bike's performance in disturbed air. An additional race outing is scheduled for the Malaysian Grand Prix in October to assess the V4 in hot weather conditions, continuing Yamaha's commitment to rigorous development.
Reflecting on Innovation: The Path to MotoGP Excellence
The debut of Yamaha's V4 MotoGP prototype underscores the relentless pursuit of innovation in motorsports. This initial public test, marked by a mix of encouraging performance and expected developmental hurdles, reminds us that significant advancements often come through iterative processes and dedicated effort. It highlights the importance of adapting to challenges, learning from every track session, and continuously refining designs to push the boundaries of technology. For Yamaha, this V4 project represents not just a new engine configuration, but a broader commitment to regaining their competitive standing, emphasizing that even seasoned giants must continually evolve to thrive in an ever-demanding arena.
