Fabio Quartararo's Yamaha V4 Struggles: Sepang MotoGP Test Analysis (2026)

The Yamaha V4's Future: A Worrying Reality Check at Sepang MotoGP Test

As Fabio Quartararo headed back to Europe, Yamaha's Sepang MotoGP test hit a snag, with a technical issue halting progress on day two. The French rider had already completed two days of testing on the new V4 engine, but his assessment was concerning.

The V4's Competitiveness in Question:

Quartararo, the 2021 world champion, believed the V4 was significantly behind its competitors, even before the technical setback. His lap times seemed to confirm this, finishing 0.851s behind Ducati's Marc Marquez on day one, with the next Yamaha rider, Jack Miller, further down in 14th.

"I can't claim confidence," Quartararo admitted, acknowledging their struggles. "But I'll give it my all and hope for the best."

Adapting to the V4:

Despite spending his entire MotoGP career on Yamaha's Inline4, Quartararo doesn't think he needs more time to adapt to the V4. He quickly identified areas for improvement, but also noted that their V4 differs from others. Technical issues in turning, traction, electronics, grip, and power require attention.

The Performance Gap:

Quartararo's limited track time made it challenging to compare Yamaha's V4 to its rivals. However, the gap was evident, with other manufacturers posting impressive lap times on the first day. Yamaha's V4 needs a performance boost, as Quartararo's top speed was notably slower than KTM's Enea Bastianini on day one.

Technical Insights:

An interesting observation was Quartararo's consistent top speed of 333.3km/h, suggesting a rev limit. Normally, top speeds vary due to factors like slipstreams and traction. In comparison, Marc Marquez's Ducati achieved a higher average top speed of 342.4km/h.

Yamaha's Next Steps:

Due to its concession status, Yamaha can modify the V4 engine throughout the season and conduct private tests. This flexibility could be crucial in addressing the performance concerns raised by Quartararo.

Controversial Speculations:

Some speculate that Quartararo's decision to join Honda in 2027 is influenced by Yamaha's struggles. Could this be a sign of a potential shift in the MotoGP landscape? And what does it mean for Yamaha's future in the sport?

Looking Ahead:

Quartararo will return to the V4 at the Buriram test in February. Yamaha resumed testing on day three at Sepang, with Alex Rins finishing as the fastest M1 rider, but still behind the leading manufacturers.

Where would Quartararo have placed if the test continued? If his pace from day one held, he would have been eighth, close to the top KTM time. But the gap to the leading manufacturers remains a concern.

The Big Question:

Is Yamaha's V4 engine truly 'super far' behind, or can they turn things around with further development? The Sepang test has raised intriguing questions about the future of Yamaha in MotoGP. What do you think? Are Yamaha's struggles a temporary setback, or a sign of deeper issues?
