The 2026 racing season is already heating up, and one rider has just thrown down the gauntlet in a big way. As the second day of the Sepang Shakedown Test came to a close, Jack Miller stormed to the top of the timesheets, piloting Yamaha’s new V4 project to a blistering 1’57.908 lap time—a full second quicker than last year’s benchmark. But here’s where it gets controversial: is Yamaha’s V4 engine finally living up to the hype, or is this just a fleeting moment of glory? Let’s dive into the details and find out.
With the Malaysian sun blazing and humidity levels soaring, Day 2 of the test offered a stark contrast to the cooler conditions of Day 1. This was a crucial opportunity for factory test riders, manufacturers, and rookies alike to gather invaluable track time—something nearly impossible to replicate later in the season. For Yamaha, the day was nothing short of triumphant. Miller’s Prima Pramac Yamaha MotoGP team not only topped the charts but also showcased the potential of the V4 engine, leaving many to wonder if Yamaha has finally cracked the code.
And this is the part most people miss: while Miller grabbed the headlines, his teammate Fabio Quartararo quietly asserted his presence, placing both his bikes in the top five. The 2021 World Champion’s seamless transition into 2026 is a testament to his skill, but it also raises questions about the team’s dynamics. Can Quartararo and Miller coexist as frontrunners, or will internal competition become a distraction? Meanwhile, Alex Rins, another Yamaha rider, wasn’t far behind in P7, proving the team’s depth.
Rookie Toprak Razgatlioglu also made waves, shaving seven-tenths off his Day 1 lap time as he continues to adapt to the V4 Yamaha, Michelin tires, and the demanding Sepang circuit. Yamaha’s test team, featuring Augusto Fernandez and MotoGP legend Andrea Dovizioso, rounded out the manufacturer’s strong showing with a best time of 1’59.351.
KTM wasn’t far behind, with Pol Espargaro finishing just 0.025s behind Miller in P2. The KTM clan’s consistency near the top is impressive, but it’s worth asking: can they maintain this pace when the full-time riders take over? Dani Pedrosa and Mika Kallio also contributed solid performances, with Pedrosa completing 47 laps and placing both his RC16s in the top ten.
Over at Honda, Aleix Espargaro led the charge with a 1’58.066 lap, finishing third and just 0.133s behind his brother Pol. Despite a technical issue, Aleix’s performance highlights Honda’s potential, though it remains to be seen if they can close the gap to Yamaha and KTM. Diogo Moreira continued his adaptation, breaking into the 1’59s and showing steady progress.
Ducati’s Michele Pirro put in a solid effort, completing 46 laps and setting a best time of 1’59.155—just 1.2s off Miller’s pace. After a turbulent Day 1 focused on aero development, Ducati seemed to find their rhythm, but will it be enough to challenge for the top spots?
Finally, Aprilia’s Lorenzo Savadori was the busiest rider on track, tasked with fine-tuning eight bikes for pre-season testing. His focus on the Trackhouse bikes and the decision to standardize the chassis used by Marco Bezzecchi and Jorge Martin in 2025 suggest Aprilia is doubling down on consistency. But with aero development still pending, are they leaving too much to chance?
As the dust settles on Day 2, three manufacturers sit within a tenth and a half of each other at the top, with Yamaha leading the charge. But the real question is: can they sustain this momentum? With one more day of testing in Sepang’s heat and humidity before the full-time riders take over, the stage is set for an electrifying season. What do you think? Is Yamaha’s V4 the real deal, or is this just a temporary surge? Let us know in the comments!
