Jack Miller has weighed in on the V4 or inline-four debate in the midst of Yamaha's engine dilemma.

At the end of the 2024 MotoGP season Yamaha shocked the paddock as they announced that they were developing a V4 engine. This decision would see the inline-four engine disappear from the paddock with all manufacturers choosing the V4 direction.

However, Jack Miller has recently stated that the debate over whether a V4 engine is better than an inline-four engine 'is a fad'.

Miller has used V4 engines during his MotoGP career at Honda, Ducati and KTM. But he believes that Yamaha's 2025 inline-four engine is 'strong'.

"Not so much. You ride every bike differently," he said when asked at the Sepang pre-season test if he needed to adjust his riding style to the inline-four.

"As a rider, you understand what the bike needs. My riding style hasn’t changed. You ride how the bike allows you to. If it allows maximum corner speed, that’s what you do. If you realise ‘s*** I can turn’ you keep working in that direction.

"Most motorcycle riders can work that out. We’re simple fellas but we can work that out. It’s easy to work out what the bike wants from you. The character of the engine is different.

"But it’s awesome to step onto one of these things. It’s different, the power curve. It’s a considerable amount different even to the bike I rode in Barcelona.

"I have rode screamers, big bangs, and now an inline. It doesn’t matter if it’s a Yamaha 450, a Honda 450, or a motocross bike - the power curve is always different.

"It does what it does very well. I believe this whole ‘V4 or no V4’ is a fad. I don’t believe it’s set in stone that you need a V4. There are pros and cons to everything. The inline-4 that we have, at the moment, is strong."
