It was another intensive day of work for Prima Pramac Yamaha MotoGP on the opening day of the Spanish Grand Prix at Jerez, with the focus firmly placed on development as the team introduced a range of new engine and chassis components brought from Japan. Some of the updates showed clear signs of improvement and offer promising direction for future development, while others did not deliver the expected results. The engineers will now analyse the data in detail to understand the discrepancies, especially as certain parts had shown positive feedback during recent testing. As a result, Saturday will remain focused on refining the package, with Monday’s official test already shaping up to be a key opportunity to continue this work. Toprak Razgatlıoğlu completed 31 laps and finished the day in 18th position, narrowly missing the opportunity to place himself higher up the standings. The Turkish rider focused on understanding the new components and continuing his adaptation process, making the most of the available track time despite not finding the final step needed for a stronger result. Jack Miller, who completed 42 laps, also dedicated his day to gathering valuable data and evaluating the updates, ending the session in 20th position. Like his teammate, the Australian was unable to extract the lap time needed to improve his standing, but contributed important feedback for the ongoing development work. This means both riders will have to go through Q1 on Saturday morning, aiming to secure a place in Q2 as the weekend continues.
