After a scuffle off the line through Turns 1 and 2 at a dry but cool MotorLand Aragon, it was Team Suzuki Ecstar rider Maverick Viñales who emerged from the melee to turn his front row start into the early lead in the race. With the front group close all the way down to P8, Marquez soon struck to take the lead, before a wobble through Turn 7 saw the championship leader drop back into the group slightly, down to P5. Lorenzo was the man on the chase behind new leader Viñales, with teammate Valentino Rossi in very close company.
The lead began to stretch for the Silverstone winner, before it was Rossi tagged onto the back of the Suzuki rider and looking for a way past, finally making a clever but aggressive move to take the lead with 15 to go and sit the younger Spaniard up. Viñales, pushing to find a way back through, then ran wide at Turn 1 and let Marquez through to hunt down his championship rival. With Lorenzo then on the scene, the front group divided into two duels.
Once with rider from Tavullia, former apprentice Marquez moved quickly to overtake the master, through on the inside on the 'Aragon Corkscrew' and making it stick. The championship leader then had the pressure of 9 world titles close behind and trying to hang on, but Marquez kept his head down and the pace up to slowly begin to get the better of the Italian and create a gap. The pace shown by the 2013 and 2014 MotoGP™ World Champion throughout the weekend on home turf proved to have survived the trip to Sunday, as the number 93 bike started to get smaller and smaller in front of the 46 plated Yamaha - with Rossi then forced to start looking over his shoulder instead as Lorenzo and Viñales threatened.
