Ducati wasn't the only team to give its prototype 2019 fairing a public debut on the final day of the Sepang MotoGP test.

Yamaha also appeared with new aerodynamics on the factory M1 of Maverick Vinales (pictured), with the wing shape now split into two parts, on either side of the bike.

Vinales was the first rider to beat Jorge Lorenzo's unofficial 2018 all-time record this morning, before the Ducatis of Danilo Petrucci, Francesco Bagnaia, Jack Miller and Andrea Dovizioso demoted him to fourth.

Suzuki and KTM debuted their new fairing designs earlier in the week, with Honda and Aprilia yet to show their hand, with one winter test still to go.
