Pramac Ducati Danilo Petrucci topped FP1 for the MotoGP grid at the TT Assen, ahead of rookie superstar Johann Zarco and two-time GP winner Cal Crutchlow after a flurry of activity towards the end of the session.
There was drama early on as crashes for Jonas Folger and Jorge Lorenzo signaled some problems out on track – with the Red Flag then brought out for suspected oil on the circuit dropped by Andrea Dovizioso as the winner at Mugello and Assen suffered a problem.
There were no further incidents in the therefore delayed session until Petrucci suffered a late mechanical issue after the flag, quickly moving off the track and the Italian then heading back to pitlane.
