Marc VDS rider Scott Redding crashed on the opening lap at the race at the Circuit of the Americas, losing the front and taking out Pol Espargaro with him.
The race had been delayed by almost 40 minutes to clear a water spillage at turn 3, but Redding made a fast getaway from his best premier class starting position of sixth on the grid. After dicing with Spanish duo Jorge Lorenzo and Pol Espargaro for a top six position on a frantic first lap the 22-year-old lost the front of his Honda RC213V machine in the braking zone for the tight turn 11.
Redding remounted but a damaged left handlebar and footpeg forced him to retire from the race.
He said: “I’m really disappointed because I have been fast all weekend in wet and dry conditions. And after claiming my best ever qualifying result in MotoGP I was confident I could have been in that second group fighting for the top six. I had a good early battle with Lorenzo in the first three corners and in turn 11 he stopped mid-corner to pull it back round and I was in a little bit too hot and I think I clipped the back of him and went down. I got going again and wanted to stay out in case it rained but the left footpeg broke off, so I had no gears and had to retire. We can take a lot of positives from the weekend but it is disappointing not to get a good result at the end of it.”
