Misano, Italy – September 16, 2025 – Just hours after the high drama of the San Marino Grand Prix, MotoGP returned to business with a crucial post-race IRTA test at Misano. The day saw Pedro Acosta (Red Bull KTM Factory Racing) bounce back from Sunday frustration to top the timesheets ahead of Alex Marquez (BK8 Gresini Racing MotoGP) and home hero Marco Bezzecchi (Aprilia Racing). Meanwhile, Yamaha’s much-anticipated YZR-M1 V4 prototype made its full-squad debut.

After a tough Grand Prix, Pedro Acosta wasted no time in showing KTM’s speed potential, leading most of the afternoon and finishing with a 0.340s advantage over the field. Despite admitting he still wasn’t fully comfortable in fast corners, his pace was close to the sub-90s barrier.

• Brad Binder improved late to finish 14th.
• Enea Bastianini (Tech3 KTM) tested setup ideas and finished 12th, one spot ahead of Maverick Viñales, who worked on regaining strength in his recovering shoulder.

Yamaha: V4 Prototype Makes Its Full-Squad Debut
