Maverick Vinales set a new unofficial all-time Sepang lap record during the start of Friday's final day of official MotoGP testing... then Ducati's Danilo Petrucci went even quicker!

Monster Yamaha Vinales, quickest with a 1m 58.897s on day two, rocketed to a 1m 58.644s on his eighth lap of the day. That beat the previous unofficial fastest ever two-wheel lap at Sepang, which was a 1m 58.830s by Jorge Lorenzo one year ago for Ducati.

But Lorenzo's replacement Petrucci then set a stunning 1m 58.239s, with team-mate Andrea Dovizioso slotting into second ahead of Vinales with a 1m 58.538s... until Pramac riders Jack Miller and then rookie Francesco Bagnaia took over second place, making it an all Ducati top four.
