The rumbling in the MotoGP paddock is intensifying: Yamaha is preparing for its rebirth. At the heart of this excitement is a project long thought impossible for the Iwata-based firm: a V4 engine. After decades of loyalty to the famous inline-four, the Japanese brand is preparing to turn a historic page. And the first tests have already generated a lot of buzz.
It is Jack Miller, Pramac Yamaha, which sets the tone. After two test sessions, the Australian displays measured enthusiasm: " I'm happy with the direction the V4 has taken " he confides, all smiles. " Rear grip has improved significantly »
But behind this satisfaction lies a straightforward observation: “ the raw power of the engine remains a weaknessWe need to get a few more horses out of it. »
On the long straights of Misano, the Yamaha V4 was still timid in the face of the red missiles of Ducati or to the Austrian cavalry of KTMMiller, however, remains convinced that the engine has enormous potential:
« It's a new project, but It's easier to find power than to correct a chassis. »
Behind the scenes, a real struggle for influence is taking place between engineers loyal to the "inline-four" philosophy and those in favor of radical change.
The former defend the legendary precision and smoothness of the inline-four; the latter advocate the modernization essential to compete with Ducati, Aprilia, KTM et Honda, all of which have long since switched to V4. This internal tug of war could well redefine the technical trajectory of Yamaha for the entire decade to come.
The decisive test for Yamaha: Sepang and Valencia
The V4 will make a new appearance at Sepang, with Augusto Fernandez on the handlebars for a wild-card role. A final outing is also planned at Valencia, a symbolic stage for the end of the season and technological transitions. These two meetings will be crucial in determining whether the V4 will officially take over from the current M1 in 2026.
Not everyone is convinced. fabio quartararo, the emblematic figure of the project Yamaha current, expressed his frustration after the Misano tests:
« It's not the revolution we were hoping for yet. I'm not sure the V4 will be ready for 2026. »
A caution that contrasts with the combative optimism of Miller, who is preparing to celebrate his 250th Grand Prix start at Phillip Island:
« It feels great to reach this number, but I'm not here to count. I still have a lot to give, and the best is yet to come »
For Yamaha , the stakes are colossal. The transition to V4 would represent the boldest departure since the 2002 M1. If the promised power materializes, the manufacturer could finally close the gap between itself and its European rivals.
But if the project fails, the in-tune brand risks getting bogged down in a painful transition, undermined by internal struggles and the pressure of an unforgiving schedule.
One certainty: the world of MotoGP holds his breath. The roar of the V4 Yamaha could well herald a new era, or the last battle of a giant in search of rebirth.
