Crutchlow went from sixth to first with three minutes remaining in the session, deposing Jorge Lorenzo with a lap of 1m43.963s.

The previous benchmark - Lorenzo's 1m44.202s - had stood for many hours before that, while during the morning the top spot had been occupied by his future Yamaha replacement Maverick Vinales and his 1m44.310s lap.

Lorenzo and Vinales would make up the top three behind Crutchlow at the chequered flag, with Ducati's Andrea Iannone fourth and Vinales' Suzuki teammate Aleix Espargaro making up the top five.

Having missed the first in-season test day at Jerez, Avintia was present this time, with a sole bike for Hector Barbera, who lapped sixth-fastest.

Marc Marquez and Valentino Rossi, the duo who battled for victory in Sunday's Catalan Grand Prix, ended up 8th and 11th.

The focus of the test was, as usual, tyres and electronics, with Michelin giving teams three rear tyre options to try out.

Three of MotoGP's 21 regular-season entries did not put a time on the board in the eight-hour test, with Aspar's Ducati Desmosedici GP14s absent alongside one of Avintia's GP14s.
