Dani Pedrosa put the second factory Honda in fourth with his final flier of the 45-minute session.

Scott Redding lapped fifth fastest on the satellite Marc VDS Honda, ahead of factory Ducati rider Andrea Dovizioso and Tech 3 team-mates Bradley Smith and Pol Espargaro.

Cal Crutchlow was ninth for LCR Honda, a tenth of a second clear of Andrea Iannone, the Italian riding with a dislocated shoulder.

Eugene Laverty ended the session as the fastest of the Open riders in 11th position for Aspar.
