Toprak Razgatlioglu delivered a downbeat assessment after the Sepang pre‑season MotoGP test, saying he expects to “probably struggle in the first five races” as he adapts from World Superbikes to MotoGP machinery. He completed the test with a best lap of 1:58.326, recorded around 18th–19th on the timesheets, well adrift of pacesetter Álex Márquez’s 1:56.402. After four-and-a-half days on track, he reported learning “something, but not a lot,” and said the five consecutive days left him physically tired, underlining how different the demands of a MotoGP race bike are compared with production‑based superbikes.

The Sepang sessions also exposed technical and setup problems within Yamaha’s new V4 package. The factory briefly halted running when a Yamaha V4 stopped on track, before resolving the engine issue and returning to action. Razgatlioglu highlighted ergonomic and handling challenges that “you can’t turn with the throttle,” and he has had to ride the YZR‑V4 more like a Moto2 machine, explaining that suspension changes are planned to improve turning. He reported improved braking after trying a different seat and reattaching the rear wing (earlier runs had the wing removed because his original seat exceeded height limits), but remained uncertain about Michelin rear‑tire wear and said tire behavior still limited his ability to hit his target lap time.

Others outside Yamaha framed Sepang as a learning and diagnostic outing. Pedro Acosta publicly urged Toprak to be cautious and not to overload expectations during his rookie transition, while Carlos Checa called him a likely top‑five rider but flagged two main uncertainties. The first is how well Yamaha’s new package will perform, followed by whether Toprak can adapt quickly to Michelin tires in the premier class. Yamaha plans further setup work and new parts at the Buriram test in just over two weeks, including additional rear‑wing trials and a possible 12‑lap race simulation to evaluate tire behavior. Taken together, the Sepang test highlighted both rookie adaptation issues and early reliability/setup and tire concerns for Yamaha’s V4 prototype, leaving Toprak’s immediate race competitiveness cautious rather than assured as the season opener approaches.

Reports before the first official 2026 pre-season test at Sepang claimed Fabio Quartararo had signed a two-year deal to join Honda from 2027. However, the rider publicly denied a completed agreement, while confirming HRC remained one of the options he was considering. The Sepang test itself was disruptive. Quartararo crashed on day one, broke a finger, and missed the remainder of that session, then encountered an engine problem Yamaha could not fix during the test. Yamaha also missed running after an unexpected engine issue described by team management as something they had “never had” before, as Alex Rins posted Yamaha’s best finish (12th). Team sporting director Massimo Meregalli said the Sepang incident did not change decisions on Quartararo’s future and characterized the interruption as a delay that pushed parts of the negotiation and testing program toward the next test.

Yamaha acknowledged it had reduced engine revs as a protective measure while continuing the development of its new V4, and planned to complete unfinished work during the upcoming Buriram test. The manufacturer emphasized continuity of its V4 program and insisted contract talks over 2027 were proceeding despite the Sepang interruption. Quartararo himself denied reports he had already signed for Honda even as questions about Yamaha’s pace of development and testing reliability intensified. Media reports and team comments linked the technical setbacks at Yamaha with increased speculation over the rider market, rather than presenting any confirmed move.

Honda presented a contrasting picture of forward momentum at Sepang. Team manager Alberto Puig praised Quartararo as “fantastic,” highlighted steady technical progress at HRC, including a lighter bike and improved engine response. The former rider cautioned that immediate wins could not be guaranteed. Joan Mir set the fastest time on day two, in what was reported as the quickest Honda lap around Sepang, and described the current RC213V as the best bike he had ridden, adding weight to Honda’s on-track gains. Puig repeatedly denied that anything for 2027 had been decided, and said Honda would prioritize its current roster while seeking riders who were both fast and intelligent. He noted that Johann Zarco and Diogo Moreira were already locked in with LCR through 2027, leaving factory-team seats contested between Mir and Luca Marini. Puig framed the 2026 contract season as chaotic and said on-track results and the evolving rule environment would shape final decisions once the season got underway.

Marc Marquez returned to the track at the Sepang pre‑season test and delivered a mixed but constructive outing. He was fastest on the opening day, but endured a roller‑coaster three days of running, ending fourth on the final day, around 0.4 seconds behind his brother Álex Márquez’s best lap. In sprint‑simulation work, he posted a best simulation lap of 1:57.602 and completed 10‑lap runs with averages in the 1:58.2–1:58.3 range. “The Ant of Cervera” showed competitive race‑pace potential despite not feeling fully 100% fit. Marquez completed the planned program using 2025 front aero on both machines while sampling 2026 aero, and suffered a low‑speed crash at Turn 1 after an aero change altered the Ducati’s balance. The reigning champion was uninjured and able to continue evaluating settings.

Beyond lap times, Marquez stressed caution about interpreting Sepang data. He warned that grip levels in Malaysia were unrealistically high and that tire usage and track conditions can skew sprint runs. Ducati displayed notable depth at the test, but Marquez said “two, three riders are faster than me” and highlighted Francesco Bagnaia, Marco Bezzecchi, and others as genuine threats. His words underline his view that the 2026 championship will be fiercely competitive. He framed testing as information gathering that must be validated under race conditions, pointing to the upcoming Buriram (Thailand) test on 21–22 February as a more decisive rehearsal because the season-opening race follows shortly afterwards.

Looking ahead, Marquez described the Sepang work as a positive step while emphasizing the need to protect his fitness and to keep evolving. A MotoGP title is earned across 22 race weekends, and riders must “reinvent” themselves year to year. His priority will be to close the gap to the riders ahead and to refine race pace and bike balance at Buriram and in the early races, using the Sepang data as a baseline rather than a final verdict on form.
