Intro

The Yamaha V4 YZR-M1 made its debut at Misano, and it’s a complete reset for the team – not just a new engine. By moving from the long-serving inline-four to a compact V4, Yamaha is chasing straight-line punch, stronger braking support, and data gathered under the heat of a race weekend. That’s why it matters: the project isn’t about headlines today, it’s about building a winning platform for tomorrow.

What is the new Yamaha V4 YZR-M1?

This is a clean-sheet MotoGP prototype built around a 1,000 cc V4, dressed in an all-blue corporate livery and paired with a newly designed chassis. The goal is simple: to gather real GP data and stress-test the new bike under race pressure, not just to chase a fast lap time. Think of it as Phase 1 – measure first, optimize fast.

Why did Yamaha switch to a V4 engine?

By moving to a V4, Yamaha can achieve tighter packaging, more flexible weight distribution, and aerodynamic gains that are difficult with the wider inline-four. The target is clear: stronger acceleration, better draft behavior, and more rear grip – areas that matter when dicing with Ducati on a long straight. It also positions Yamaha well for upcoming rules that reward narrower, more efficient layouts.

What are the key design changes?

Under the skin sits the big move – the V4 layout – wrapped in a chassis built specifically to house it and work the rear tire harder under drive. The aero is a fresh chapter too, with shapes that look far more aggressive than the current M1’s surfaces. Hardware remains top-tier and familiar—Öhlins suspension, Brembo braking – but the philosophy is different: integrate engine, frame, and aero as one system.

How does the new bike handle?

Early track whispers are optimistic: better rear grip, more support on the brakes, and a calmer exit drive. Now, the team’s challenge is to blend the new straight-line power with the M1’s signature front-end feel, which has always been its strength. It’s a balance game – gain speed without dulling the M1’s cornering edge.

When will the V4 YZR-M1 race full-time?

This weekend is about learning, not lap-time chest‑beating. The roadmap points toward a 2026 race debut if testing stays on track, with 2025 acting as the proving ground for reliability, rideability, and race execution.

Who is riding the new prototype?

Test rider Augusto Fernández takes up wild‑card duties at Misano to stack meaningful data under race conditions – launches, pit cycles, traffic, tire life. Factory feedback folds in during test days, compressing development cycles between private runs and GP weekends.

Closing note

This is Yamaha’s boldest pivot in years: a move to V4 power, a rethought chassis, and aero that looks built for elbows‑out racing. If testing goes well over the next few months, 2026 won’t just be a debut – it could be the year Yamaha finally converts its development work into race wins.
