On the Monday after the Austin round of MotoGP, the Suzuki team stayed on to do an extra private test. Aleix Espargaro and Maverick Viñales had hoped to start relatively early, but heavy overnight rain left the track both wet and dirty, taking some time to dry out. When they did start, the times were poor – around 2'08, rather than the 2'05s both riders had been posting in the race. But conditions improved as the day went on, and the session turned into a very productive test for both riders.
After two race on back-to-back weekends, there was little time to be testing new parts. Both men had some new electronics to try, aimed at helping the seamless gearbox be a little smoother. They also both tried the 2016 chassis again, after having spent the first three races on the 2015. Aleix Espargaro was not entirely convinced, saying the frame was stiffer, but it was also less agile. That meant balancing braking stability against cornering ability. For Espargaro, the time lost in the corners would not be made up on the brakes, certainly not in qualifying.
