JACK MILLER SAYS SILVERSTONE WIND MADE AERO TESTING HARD TO READ

Jack Miller admitted that it was “very f*****g difficult to tell anything” about the aero changes he brought to Silverstone after a windy Friday disrupted the team’s ability to properly evaluate an updated package.

Riding for Pramac Yamaha, Miller used his new aero specification across the British Grand Prix’s two practice sessions, with the goal of understanding how the update would translate into performance. The work paid off in terms of qualifying progress: he secured a direct place in Q2 by finishing ninth on Friday.

However, Miller said the conditions made meaningful comparisons almost impossible. He pointed to the crosswind as the main issue, explaining that “no two corners felt the same” throughout the day. In his view, even small changes in wind strength meant that laps could feel different from one another, making it hard to isolate what was coming from the aero versus what was coming from the weather.

Asked about the update, Miller drew a parallel with Yamaha’s own approach, telling the media, “Honestly, you're asking the same as Yamaha.” He elaborated that the wind was “pretty bad,” and that the track’s character in those conditions made it tough to feel a clear aero effect. “You know, you have a little bit less wind, a little bit more wind; some laps feel better than others,” he said, adding that Silverstone can be particularly challenging when conditions are unstable.

Despite the evaluation difficulties, Miller suggested the bike itself was coping reasonably well with the gusts. He said the Yamaha was “handling the wind pretty good,” especially in crosswind situations, and he noted that he had seen some other manufacturers appear to struggle more. “In general, we're reasonably strong,” he said.

Miller also looked ahead to Saturday, expecting a fresher engine for the next day. “We'll have a fresher engine tomorrow, so hopefully we can be a little bit closer to the front,” he said, framing the upgrade as part of the broader plan to improve competitiveness after Friday’s mixed conditions.

On the performance side, he described several areas where he felt comfortable. “I feel good in braking, I feel good mid-corner,” Miller said. He also highlighted the bike’s responsiveness, stating that it was “changing direction pretty good.”

The remaining work, in his words, was about improving how the bike behaves at the limit—particularly on tyre edge grip and the ability to build speed out of the final corner. He said he wanted to “work a little bit more on edge,” aiming to help the machine “hook up a little bit better” and to generate more speed through the last corner.

Miller explained that finding that extra pace while keeping the tyre from overheating was difficult. “If I can pick the bike up and drive it, it's driving pretty good,” he said, before adding that “trying to build speed on the edge of the tyre, it's really hard to keep the thing—keep contact, let's say—without lighting it up too much.”

With Friday’s aero conclusions blurred by the wind, Miller’s focus for the evening was to translate what he could feel into actionable setup ideas. “So, we'll try and work on that tonight and see if we can come back with some ideas,” he said.

He also acknowledged the competitive nature of Friday’s Q2 qualification, remarking that it had required “suck[ing] the arse out of Marc [Marquez] and Alex [Marquez] to get through,” while still emphasizing the value of arriving at the weekend with a Q2 place already secured. “But we'll see what we can do tomorrow,” Miller concluded, “but it's always nice going to bed on a Friday and being in Q2 already.”
