Jack Miller🐲 says Yamaha is “leaving no stone unturned” with the development of its 2025 MotoGP bike as pre-season testing begins.

The Australian retur♍ns to the Pramac fold in 2025 after two difficult years with the factory KTM squad, and will ride Yamaha ma🌠chinery 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 over the 🎐winter.

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

“An🔯d I believe we’re in the buildi♌ng process, so for sure I think there are a lot of hard-work days ahead.

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

“They are leaving no stone unturned to try to get the M1 back to where it ♛🃏belongs at the front.”

Miller says riding for Yamah✨a is “a massive honour” having been a fan 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 a𒆙 seat at the Pramac squad became available 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 working back wit꧅h the Pramac team it feels like a homecoming for me, very welcoming.

“Looking forward to doing those peop♓le proud who have taken a chance or a gamble on me.

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

“I look forward to being a small chunk in 🀅the success story of Yamaha 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 Thai𓄧land on 12-13 February.
