MotoGP race direction was officially issued a formal warning to Marc Marquez and Thomas Luthi. Marquez was warned over his pass on Luthi at the start of the last lap, while Luthi received the warning for the hard slap he gave on Marquez' throttle arm on the cooldown lap. Marc Marquez passed Thomas Luthi on the way down the front straight. although there were no 'touch' between them, but it pulled Luthi wide.
Marquez told "I passed him on the straight, I was completely past him, and when I arrived at the braking point, I braked like I always do, and I saw him pass me on the left."
"He has simply left no room for me," complains Luthi. "In my eyes it was not fair. He may simply not move to the left. He could have just run straight ahead. I would have let him enter the car as well. I was still at the height of his rear wheel. With my front wheel, I was almost at the level of its footrest. Then he can not simply pull to the left and to relegate me to the curb. "
"The pass was reviewed immediately, and then reviewed again later in more depth and with different camera angles, and in the context of the whole race. After the race, both riders were spoken with. The decision of Race Direction was that it was a very hard maneuver, on the borderline of acceptable racing. Marquez was warned, the equivalent of a yellow card."
"Luthi was also given a warning/yellow card for venting his obvious frustration after the chequered flag," Webb said, adding that both riders had accepted the warnings, and that as far as he was concerned the issue was done with. But the fact that a warning was issued was a clear message to all of the Moto2 riders that their actions would be subject to close scrutiny. Though no formal punishment was handed out, Race Direction were far from happy with the pass. "In this case, it was judged to be close to the limit, but not obviously malicious,"
