Jorge Lorenzo said he had 'no excuses' following his defeat by MotoGP World Championship leader Marc Marquez at Aragon.
Defending champion Lorenzo made a strong start to the race and opened a lead of one second, but Marquez proved too strong in the end as the series rookie extended his advantage at the top to a commanding 39 points in Spain.
Lorenzo, winner of the previous two races at Silverstone and Misano, said it was 'impossible' to catch his Honda rival once he hit the front.
“My tactic was to start well and open a gap like I did in the last races. I could make one second at the beginning but then simply Marc was faster,” said Lorenzo.
“When he caught me I closed the throttle to try to save some energy until the end; then he passed me and tried to go away. I tried my best to catch him but it was impossible.
“Today he was faster than me; there are no excuses. We have to congratulate him and now we think about the next races,” he added.
“The championship is more difficult now than before the race but we are going to fight for it until the end. We will try to win as many races as possible.”
Asked if he knew of any future technical improvements to his M1 for the remainder of the season, Lorenzo replied:
“We already have the fifth [and last] engine, so the engine cannot be improved. We can just improve the chassis and suspension... pray for some miracle. It's a difficult situation. We have to concentrate to win races and be motivated for next year.”
