Yamaha's Ben Spies topped the second day of testing at Sepang, but the session was once again badly affected by rain. While vastly improved track conditions in the morning saw most riders take over a second off their times from yesterday, heavy rain started after just a couple of hours, calling a premature halt to the proceedings for everyone. Once the downpour eased off a little, track action resumed as the teams started work on the wet setup of their bikes.
In the dry conditions of the morning, Spies led a Yamaha whitewash. The Texan was faster - by the slimmest of margins, a few thousandths of a second - than his factory Yamaha teammate Jorge Lorenzo, while Andrea Dovizioso ended the day as 3rd fastest, beating his Monster Tech 3 Yamaha teammate Cal Crutchlow for the first time since joining the team. Behind the Yamahas, Nicky Hayden led the Ducatis, fractionally behind Crutchlow and a quarter of a second faster than the Pramac satellite bike of Hector Barbera. Valentino Rossi continued to work on the revised electronics package of the Ducati, ending the day in 7th, behind Barbera but within a second of Spies.
