Yamaha V4 lap times: Jack Miller, Alex Rins beat Inline qualifying time on 2026 MotoGP debut

Official Test Update: Here are the updated Yamaha lap times after the conclusion of the Official Sepang Test.

Fabio Quartararo did not ride on day three due to a finger injury on day one, while all Yamaha riders were confirmed to the garage on day two while a technical issue was investigated.

Jack Miller did not beat his Shakedown best (but matched his time attack best during a Sprint simulation). Alex Rins did improve to finish 0.25s behind his best Inline lap time during limited Yamaha running on the final day.

For comparison, the fastest lap at the 2025 Sepang test was a 1m 56.493s by Alex Marquez (Gresini Ducati), who set an almost identical 1m 56.402s to lead the 2026 test.

Day 3 update: Alex Rins' late improvement on Saturday's final day of the Sepang Shakedown meant he joined Jack Miller in beating his Inline qualifying time from last year's Malaysian MotoGP on the new Yamaha V4.

Rins and Miller now head into next week's Official test needing to find half a second to beat their best-ever Inline M1 Sepang laps, set by both at last year's Official test.

Fabio Quartararo finished as the fastest Yamaha at the 2026 Shakedown, but didn't beat his qualifying time from last October.

The Frenchman also needs to find almost one second to set a personal best Sepang lap time on the V4 next week - still an achievable goal, depending on the weather...

• 2026 Sepang MotoGP Shakedown Test: Results - Day 3 (FINAL)

Ranked by 2026 Shakedown time.

Original Story: Ever since Yamaha confirmed it was developing a new V4-powered MotoGP machine, the factory set a clear target of being at least as competitive as the outgoing Inline-powered M1 as soon as possible.

While the prototype seen last season was a clear step behind the Inline bike, not least due to limited engine performance, Jack Miller enjoyed an encouraging debut on the latest version of the V4 during Friday’s Sepang MotoGP Shakedown.

After skipping day one, Miller joined factory riders Fabio Quartararo and Alex Rins in completing his first laps of the pre-season on day two.

It ended with the Pramac rider not only putting the V4 top of a MotoGP timesheet for the first time, albeit with a limited rider line-up, but also beating his own Inline qualifying time (for 11th on the grid) at last October’s Malaysian Grand Prix.

Miller's next target will be his personal all-time best Inline Sepang time of 1m 57.452s, set at the official test a year ago (see table below). But with one more day at the Shakedown, then three days at the Official test, that looks set to fall.

Nonetheless, there is still some way to go to match Quartararo’s 1m 57.195s from qualifying last season, which earned fourth on the grid.

An even bigger challenge will be Yamaha’s all-time Sepang record of 1m 56.724s, set by Quartararo during testing last year, a lap the Frenchman later described as “fake” due to near-perfect track conditions.

The former MotoGP champion, reported to be leaving Yamaha for Honda in 2027, began 2026 with a best of 1m 58.135s on Friday.

Rins also has margin to improve relative to the inline M1. The Spaniard set a 1m 58.657s on day one of the Shakedown, compared with a 1m 57.945s in qualifying and a 1m 57.351s in testing last year.

Miller’s rookie Pramac team-mate Toprak Razgatlioglu, in action on both days of the Shakedown, has a best lap so far of 1m 58.805s.
