Yamaha is doubling down on innovation with a one-day private test on Wednesday (19/11/2025) at the Circuit Ricardo Tormo, following the official Valencia MotoGP test. Monster Energy Yamaha MotoGP and Prima Pramac Yamaha have stayed behind while most teams packed up, using this extra day to fine-tune their radical new V4 engine before the winter break.
The additional day is more than a luxury—it’s a necessity. After Tuesday’s sessions were hampered by a slowly drying track, Yamaha engineers and riders are determined to maximize every lap today. The goal: gather critical data that will shape the 2026 season.
Team Director, Monster Energy Yamaha MotoGP Massimo Meregalli highlighted the purpose behind the extended test:
“We were not so much looking at performance but rather focused on gathering as much data as possible. This extra day will most likely give us the time needed to evaluate the updated parts, such as a different chassis and a different aerodynamics package, and we can also work on set-ups.”

V4 Engine: A Bold Shift
Yamaha’s move from its long-standing inline-four to a V4 configuration is one of the biggest technical shake-ups in recent MotoGP history. Prima Pramac rider Jack Miller summed up the mood:
“Decent first day on the V4. Obviously, some work needs to be done, but we’re in the right direction. We wouldn’t go with the V4 if we didn’t think the potential was going to be bigger than the inline.”
Factory stars Fabio Quartararo and Alex Rins, alongside Miller and newcomer Toprak Razgatlioglu, are providing Yamaha with invaluable feedback on chassis, electronics, aerodynamics, and engine behavior. Quartararo stressed the importance of private test session:
“Tomorrow is going to be important, especially to find the way with chassis, electronics, engine, and aerodynamics. Today was short and rushed, but I like the way of riding on the V4.”
For Razgatlioglu, adapting to MotoGP machinery and Michelin tyres remains a priority. Prima Pramac boss Gino Borsoi explained:
“The plan is to start with a slightly different set-up to help him in areas where he’s struggling with the front. Rear grip complaints are more about tyre usage and electronics, but we can help him with the front tyre.”
