After leading an Aprilia one-two on Saturday, Aleix Espargaro broke the all-time unofficial Sepang♒ lap record at the start of Sunday's final day of te𝓰sting.

But 🐠it didn't last long, with Enea Bastianini then taking last year's Ducat🉐i GP21 to a time 0.026s quicker!

Danilo Pet𒐪rucci set the previous unofficial record of 1m 58.239s during pre-season testing with Ducati in 2019. Espargaro then clocked a 1m 58.371s to lead day one of MotoGP's first Malaysian laps since 2020 on Saturday.

The cooler morning temperatures again meant a fast start to Sunday, with both Pramac Ducati's Jorge Martin and Suzuki's Alex Rins dipping under Espargaro's🐼 day one best. But the Aprilia rider responded on his eighth lap with a 1m♏ 58.157s, 0.086s quicker than Martin and under Petrucci's record.

Bastianini, fourth ﷽on day one for the new-look Gresini Ducati team, then set his 1m 58.131s stunner on his 13th lap.

The fastest Sepang laps are usually setꦗ in the first and last hour of💙 testing, meaning there's still a chance of seeing the first 1m 57s lap later today, providing rain stays away.

With no Malaysian Gr👍and Pr꧋ix for the past two years, the official MotoGP lap record remains a 1m 58.576s set by Fabio Quartararo in 2019.

Aprilia - which took its first podium with the RS-GP at Silverstone last year courtesy of Espargaro - is the only factory that still has access to technical concessions, meaning they can modify their 🦹engine design during the season and are allowed two extra engine changes per rider.
