Following the Spanish Grand Prix, Prima Pramac Yamaha MotoGP remained on track in Jerez for a crucial day of testing, completing an extensive programme aimed at continuing the development of the Yamaha YZR-M1 and refining the base set-up for both riders.

With a wide range of components and configurations to evaluate, the team worked through a demanding schedule, while also focusing on resolving some of the key issues highlighted by the riders over the course of the weekend, particularly during Sunday’s race. The objective was not only to assess new parts, but also to better understand the current package and define a clearer direction moving forward.

Toprak Razgatlıoğlu and Jack Miller both maximised their track time, making full use of the stable conditions to gather consistent data — something that had been limited during the race weekend. For Razgatlıoğlu, still in the early stages of his MotoGP adaptation, every lap remains especially valuable in building confidence and understanding of the bike, while Miller continued to provide detailed technical feedback to support the development process.

At this stage of the project, with the bike still relatively new and the team working to establish a solid foundation, track time is a key asset. The insights gathered during this test will now be analysed in detail, with the aim of translating them into further improvements in the upcoming races.

Test days like this are extremely valuable. During a race weekend, as much as you would like to try new things, the priority is always the race, so you don’t have the time to properly analyse, discuss and evaluate every option. At a certain point, you have to choose a direction and commit to it.

Days like today, instead, allow us to work more methodically, which is crucial for our development and learning process. At this stage, it’s not about refining small details — it’s about testing different solutions, sometimes very different from each other, to understand what works and what doesn’t. It’s a time-consuming process, but also a very important one.

We are fortunate to have a rider like Jack, who brings a huge amount of experience and very valuable technical feedback. At the same time, it’s impressive to see the level of input we get from Toprak — he has a fresh perspective, is very intelligent and extremely curious, and that is a great asset for the team.

It was a busy Monday for us. We had a lot to get through and tried to tick off as many items as possible. There were new parts and solutions to test, but we also focused on revisiting some of the issues we encountered over the weekend and, importantly, confirming the things that were working.

It was useful to go back over certain areas in a calmer environment and make sure we had taken the right direction, without the pressure of a race weekend. That kind of validation is just as important as trying new things.

I’m quite happy with the base chassis set-up at the moment, but at this stage of development even small changes can have a big impact and sometimes take you a step backwards. We know what we need to do — it’s about staying focused, working through our priorities, and continuing to build towards a higher level of competitiveness for the bike, the team and ourselves as riders.

We had a lot of items to test today, and it’s a shame about the small crash because it cost us around an hour of track time. It wasn’t anything serious, just a mistake, but at this stage every lap is important. 

We worked through several things, especially on the electronics, which is an area where I still need to improve my understanding and where we also need to make progress with the bike. I focused a lot on that today to give as much feedback as possible to the engineers.

Now they have a lot of data from me and from the other Yamaha riders, so I’m sure they will be very busy analysing everything before Le Mans and coming back with new ideas to test.

Days like this are also very important for me personally. On tracks like Jerez, I naturally tend to ride like I did in Superbike — it comes automatically — but this is something I need to change. Step by step, I am adapting more to the MotoGP style.
