You don’t expect to be cold in the desert. On Friday evening, most of the paddock was wandering around in short sleeves and t-shirts until after 9pm. On Saturday, people were pulling on jackets shortly after sunset. By the time MotoGP finished, people were starting to lose feeling in their hands.
It wasn’t just the temperature. The wind had picked up enormously on Saturday, blowing sand onto the track in places, and blowing any residual heat from ever nook and cranny around the circuit. It was not the normal chill of the desert evening. It was cold.
That caused more than a few problems during the evening. Session after session, class after class, riders fell, mostly at Turn 2. That is the first left-hand corner for nearly 2km, after the final right-hander before the long straight, and then hard braking for Turn 1.
That is a lot of time for the front tire to cool down, especially when there is a hard headwind blowing down the main straight, whipping the heat from the tires.
