Consistent Crutchlow
At Honda, one big focus for Crutchlow was the start; clutch feel and electronics.
He did 78 laps, was the man deposed by Quartararo's late lunge, and did his fastest lap on a new rear medium compound tyre from Michelin featuring new technology for improved grip and consistency.
Marquez on Bradl's bike
A little further down the timesheets, Jerez winner Marc Marquez (Repsol Honda Team) ended the day in seventh after 75 laps.
He set his quickest on the bike that wildcard and test rider Stefan Bradl rode in the race with carbon fibre chassis additions.
Espargaro shines
For KTM the timesheets made for good reading with Pol Espargaro (Red Bull KTM Factory Racing) as he ended the day in fourth, 0.735 off P1 after 63 laps, with team-mate Johann Zarco in P16 after 71.
They tested chassis parts, chassis settings and some engine parts.
Different Dovizioso!
Ducati were not inside the top ten by the end of the day.
Andrea Dovizioso (Mission Winnow Ducati) was P11 after 52 laps with a best of 1'37.601, but he was not trying any particular new parts, instead focusing on big set-up changes they had not use time for during a race weekend.
