After a day of prevarication, Yamaha (with the blessing of the other factories) finally cracked down on the media presence at Sepang, locking the gates to pit lane as well as the side of the track. Anyone who wasn't a member of a team wasn't getting in, and the factories could work in peace. All except Honda, who had packed up on Saturday, giving Stefan Bradl an extra day's rest ahead of the official test starting on Wednesday.
Aleix Espargaro joined the action, riding the Aprilia RS-GP alongside test rider Bradley Smith, though Andrea Iannone sat out the day with what was reported to be a minor health issue with his teeth. Jonas Folger also took to the track for Yamaha, but as he and Yamaha's other test rider, Katsuyuki Nakasuga, swapped between the two test bikes, it was hard to tell who was setting which times. Both riders looked pretty fast, and Nakasuga was doing so with the benefit of an extra day's experience. Jonas Folger had a crash in the middle of the day, causing a red flag, though Folger continued testing after the flag appeared.
