Dani Pedrosa topped the first day of MotoGP testing at Valencia as a mixture of 800 and 1000cc machines took to the track.
Honda riders Pedrosa and Casey Stoner, who had last ridden their 2012-spec machines at Misano in September, headed the times for most of the day, with Stoner in front for the majority of the time.
It was Pedrosa, though, who wound up fastest, clocking 1m32.186s on the fastest of his 40 laps, 0.136s up on his world champion teammate, who suffered from excessive chatter on the new 2012-spec tires during the day. Both RC123Vs featured revisions since the Misano test.
Ben Spies was the Honda riders' closest challenger, the American completed a marathon day of riding with his teammate Jorge Lorenzo being still unfit to return to action following injury. He was a second off the pace on Yamaha's new M1.
Randy de Puniet made an impressive debut on Suzuki machinery, the Frenchman taking a 2011-spec 800cc bike to fourth spot, ahead of the new Tech 3 Yamaha and Ducati of Cal Crutchlow and Valentino Rossi, respectively.
Andrea Dovizioso capped his first day as a Tech 3 employee with seventh spot, ahead of new Pramac Ducati rider Hector Barbera, also on a 1000cc bike.
New Moto2 champion Stefan Bradl rode LCR's 800cc Honda and was ninth quickest, while Karel Abraham completed the top 10 on his Cardion AB Ducati.
