Jack Miller believes the evolution of Michelin’s rear tires was a decisive think about tilting the technical stability of MotoGP in favor of V4 engines.
After working the inline-powered M1 all through the trendy four-stroke period and successful eight rider titles, most not too long ago with Fabio Quartararo in 2021, Yamaha will be part of its rivals in switching to V4 engines in 2026.
When requested what shook the stability, Miller, a Pramac rider who gained races with Honda and Ducati after which completed on the rostrum with KTM, mentioned: crash internet: “Rear tires. I imply, that’s apparent.
“We changed the rear tire a few years in the past, and the extra Michelin developed this rear tire, the extra it at all times was.
“However to unlock the complete potential of right now’s rear tires, it’s essential be on the bottom. It is advisable use them for stopping, mid-corner and acceleration.”
“However on the similar time, you’ll be able to’t overload it. It has a slim working time, however when it’s on, it’s fucking on!
“For those who can maximize your potential, it makes a giant distinction.”

Jack Miller brakes on his inline M1 and lifts the rear wheel into the air.
That sensitivity additionally explains why MotoGP kind fluctuates dramatically from race weekend to race weekend.
“If we will do it inside that working window, that is phenomenal,” Miller emphasised. “As you’ll be able to see, some bikes could be ‘on’ relying on the weekend. And the following weekend it is “off”.
“That is very true with Yamaha. When a truck would not have the most effective grip or different vans cannot use a softer rear, we are inclined to carry out higher.
“You do not actually discover it while you’re not utilizing it as a result of you aren’t getting the complete advantages of a gentle tire such as you would with different tires.
“However different individuals say they cannot cease (with out a gentle rear tire) and that is the way it felt after I was driving the KTM.
“For those who do not use softs, it appears like somebody is taking the brakes off, as a result of you’ll be able to’t use the rear finish as a lot to cease the bike.”

With the V4 choice, Yamaha now faces the troublesome job of beating rivals who’ve been racing with the expertise for at the least a decade in MotoGP.
Miller is assured that Iwata producers will rise to the problem.
“That is proper. I imply, they went all in on this new undertaking,” he mentioned.
In the meantime, like all MotoGP producers, Yamaha must develop an 850cc/Pirelli shoe machine for the following 2027 laws.
“Clearly, the bike goes to vary in 2027…however they needed to do one thing. That is (Yamaha) actively doing one thing to remain aggressive,” Miller mentioned of the transition to V4.
“And in ’27, they’re going to have much more data.
“Yamaha engineers have been working laborious for the previous 18 months and can in all probability proceed to take action for the following 24 months!”
“However that is the best way this sport is. It is all a studying course of for what is going on to occur within the not too distant future.”
That studying course of will proceed when the 2026 MotoGP check begins with the Sepang Shakedown from January 29-31.
