Lorenzo and fifth fastest team-mate Valentino Rossi compared the two versions of the 2013 M1 chassis currently available with the goal to decide upon one solid base set-up. If achieved, this will allow them to avoid the time-consuming task of switching between chassis during race weekends.
Honda Gresini focused on the front and rear Showa suspension of Alvaro Bautista who finished sixth quickest, while on the team's CRT machine Bryan Staring ran with a new frame.
LCR Honda MotoGP's Stefan Bradl had suffered a lack of front end grip for the entire race weekend, thus today the German hoped to modify the geometry of his bike in a bid to find a proper solution. He would end proceedings in ninth spot.
Filling the void in seventh and eighth were the Ducati Team pairing Nicky Hayden and Andrea Dovizioso, who had been highly keen to sample the revised chassis of the GP13 Laboratory bike.
Both riders conducted back-to-back comparisons with the current GP13, although test rider Michele Pirro - who had competed with the new machine over the weekend - was not on-track today.
Bradley Smith rounded out the top ten on the second Tech 3 machine. Unlike Crutchlow, Smith felt a clear benefit from the new chassis.
A selection of CRT riders - such as those of NGM Mobile Forward Racing, Came IodaRacing Project and Avintia Blusens' Hector Barbera - experimented with the first significant upgrade to the Magneti Marelli MotoGP ECU kit.
This is aimed at providing a better interface for riders and teams when working on bike setup, while on the bike itself the main performance steps are wheelie control and an 'anti-jerk' strategy that cuts engine power when between off-throttle and on-throttle situations; this should allow for a more stable mid-corner ride.
In the case of Barbera who was the leading CRT runner in 11th place, the Spaniard also looked at several new chassis components, whereas Avintia teammate Hiroshi Aoyama tried out a new frame and swingarm combination.
At PBM, Michael Laverty - who on Sunday had scored his first points with the team's own-built bike - ran new parts as well as looking into the ECU update, whereas on the outfit's ART machine Yonny Hernandez was looking to solve several setup issues, having been one of five riders to crash out of Sunday's race.
