MotoGP world champion Marc Marquez set the pace in the opening practice session for the Catalan Grand Prix at the Barcelona circuit.
The Spanish rider, aiming to bounce back this weekend after his crash in the previous race at Mugello, set a fastest time of 1:41.808 near the end of the session to outpace Honda teammate Dani Pedrosa by two tenths of a second.
Suzuki rider Aleix Espargaro finished third ahead of Yamaha's Jorge Lorenzo, the winner of the last three races.
Maverick Vinales completed a promising start for Suzuki with the fifth quickest time.
Championship leader Valentino Rossi finished down in eighth position.
Riders made the most of the session to prepare for Sunday's race, with rain forecast for tomorrow.
Aleix Espargaro was the early pace-setter of a session that started under a cloudy sky and which saw Andrea Iannone crash his Ducati early on when he went off the track at Turn 10.
The Italian's bike was not damaged, however, and he managed to return to the pits after being pushed back onto the track by the marshals.
Espargaro remained on top of the times until the final minutes when, with four to go, Pedrosa jumped to the top with a lap of 1:42.018.
Marquez took P1 with less than two minutes left despite a mistake on his flying lap, the world champion setting a new benchmark of 1:41.808.
