During the 2025 preseason MotoGP test at Sepang Circuit, Yamaha’s leading rider, Fabio Quartararo, shared several key factors that contributed to the bike’s outstanding performance. In a post-test press conference, Quartararo explained that the speed and stability of the Yamaha machine were not coincidental but rather the result of relentless efforts from the engineering team and continuous technological innovation.
- Innovative Aerodynamic Package
According to Quartararo, one of the secrets to Yamaha’s speed lies in the updated aerodynamic package. The Yamaha team has refined the bike’s design to not only reduce air resistance but also increase downforce, ensuring enhanced stability on the track—especially on long straights and during high-speed corners. “This new aerodynamic design gives us a significant advantage, allowing us to maintain high speeds without sacrificing stability in the curves,” Quartararo stated.
- Engine Optimization and Electronic Calibration
In addition to the aerodynamic improvements, enhancing the engine’s performance played a crucial role. Yamaha implemented a more advanced engine calibration along with upgrades to the electronic system. As a result, the bike now delivers a more responsive power output with sharper acceleration. Quartararo added, “The adjustments to the engine calibration and electronic system enable us to achieve optimal engine response, providing that extra boost when we push towards maximum speed.”
- Enhanced Suspension and Chassis Setup
Equally important was the focus on refining the suspension and chassis setup. The modifications were tailored to the unique characteristics of the Sepang track, allowing the bike to tackle sharp corners and varying track surfaces effectively. “We made adjustments to the suspension and chassis to ensure the bike remains balanced and responsive under all track conditions,” Quartararo explained. These enhancements have proven to be highly effective in improving both speed and stability during testing.
- Synergy Between Rider and Technical Team
Another critical factor was the close collaboration between the rider and the technical team. Quartararo emphasized that direct feedback from the rider has been invaluable for the team in fine-tuning the bike’s setup. “The strong communication between me and the mechanics provides essential insights that help us continually refine the bike. Here in Sepang, we collected a wealth of data that has been immediately applied to boost performance,” he noted.
Conclusion
Through a series of technical refinements and innovative upgrades, Yamaha managed to deliver an impressive performance during the 2025 Sepang MotoGP test session. The updated aerodynamic package, engine optimization, and enhanced suspension and chassis setup were the key elements that made the Yamaha bike both fast and stable on the track. With a solid technological foundation and a dedicated team, Yamaha and Quartararo look well-prepared to compete fiercely in the upcoming 2025 MotoGP season.
