Overview

• Yamaha publicly ran its ground‑up V4 YZR‑M1 prototype for the first time on a grand prix weekend, using Fernández as a Misano wildcard to validate the concept under race conditions.
• FP1 was interrupted by an electronics issue that forced Fernández to stop on track, and he later had low‑speed crashes in Friday’s training and again in FP2 on Saturday morning.
• Trackside reporting flagged improved grip versus the current M1 but weaker top speed in the debut outings, echoing test feedback of better braking, handling and traction.
• Factory riders cannot adopt the V4 in 2025 because Yamaha has already used its seasonal update allowance and a chassis change is required under the rules.
• Yamaha plans further wildcard and test runs at Sepang and Valencia before deciding on a 2026 rollout, and confirmed Fernández’s deal through 2027 during the Misano presentation.
