Sepang MotoGP test: Marquez leads Lorenzo and Crutchlow at Sepang

As has been the case all week, searing temperatures meant the quickest times were set early on, with Marquez's 1m59.115s for Honda coming on his 13th of 73 laps.

That put the world champion 0.322 seconds clear of Lorenzo's Yamaha, with Marquez going on to set a strong pace on long runs later in the day despite the hot conditions.

Crutchlow (pictured below) had been quickest prior to Marquez's lap, and the LCR Honda man's time kept him in third for the rest of the day.

Andrea Iannone continued to show the new Ducati's immediate potential in fourth, ahead of Valentino Rossi, Bradley Smith, Dani Pedrosa and Avintia rider Hector Barbera on the old Desmosedici, with Andrea Dovizioso 10th on the other GP15.

Aleix Espargaro kept Suzuki in the top 10 in ninth, just 0.3s quicker than rookie team-mate Maverick Vinales in 14th.

Pol Espargaro continued his run of test crashes with a fall at Turn 7. He was 11th.

At the tail of the field, MotoGP returnee Marco Melandri endured a miserable week on the Gresini-run Aprilia and was slowest on all three days.

Wednesday was the final day of normal running for the test, but most of the field will be engaged in Michelin tyre testing on Thursday ahead of the French firm replacing Bridgestone in 2016.

No times or official information about the Michelin test are likely to be revealed, but it will be the works race riders' first chance to try the new tyres, which have so far been limited to development riders.
