Overview
- Yamaha paused Sepang Day 2 to probe a V4 engine issue, then resumed running for the final day after overnight checks, but Fabio Quartararo did not return following his Day‑1 crash and broken finger.
- Marc Marquez led Day 1 on his comeback from a shoulder fracture as Ducati continued aero trials, KTM evaluated a new chassis and swingarm, and Aprilia tested rear‑wing concepts.
- Joan Mir topped a rain‑affected Day 2 for Honda as late showers limited slick‑tyre time and prevented further time attacks.
- The final day proceeded with Yamaha’s remaining riders back on track as manufacturers prioritized mileage and selections ahead of the Buriram test later in February.
- In F1, Williams completed a first shakedown of the delayed FW48 at Silverstone and confirmed plans to join next week’s Bahrain testing after missing the Barcelona running.
