Jack Mi𝐆ller says Yamaha is “leaving no stone unturned” with the development of its 2025 Moto⛎GP bike as pre-season testing begins.

The Australian returns to the Pramac fold in 2025 after two difficult years with 🎃the factory KTM squad, and will ride Yamaha machinery for the first time in his career.

Miller, who has already been on track this week at the Sepang shakedown, comes to the Yamaha project “in a building process” but is confident in the work its engineers have been doing ove🎶r the w🦹inter.

“I𒅌 believe the guys have been working extremely hard from our test in Barcelona at the end of last season to where we are now,” he told Sport TV.

“And I believe we’re in the build⛦ing process, so foꦆr sure I think there are a lot of hard-work days ahead.

“But fortunately for us we have extra days 🐎to test and we have no༺ shortage of parts coming from Yamaha.

“They are leaving no 𒁃stone unturned to try to get the M1 back to where it belongs at the꧟ front.”

Miller says riding for Yamaha is “a massive honour” having been a faꦛn of the brand as a child, and is also keen to “do those people proud who have taken a chance” on him.

At one stage last year, Miller’s MotoGP career looked over before a seat at the Pramac squad 🐲became 𒁏available in the summer.

“Looking forward to it,” he said.

“A new challenge, trying to learn a new bike.

“So, looking forward to that and I mean wo𝔍rking back with the Pramac team it feels like a hꦗomecoming for me, very welcoming.

“Looking💝 forward to doing those people proud who have taken a chance or a gam𝓡ble on me.

“Working with Yamaha is such a pleasure, [it’s] such a massive company, I was a massive fan of it growing up and being able to ride the M1 n𒉰ow is a massive honour for me.

“I look forward to being a small chun𒁃k in the success story of Yamah🌱a going forward.”

The first official pre-season test begins this week and runs from 5✅-7 February in Malaysia, before two final days of running in Thailand on 12-13 February.

As a concession manufacꦺturer, Yamaha will be able to test freely during the season with its races riders.
