Following Sunday's season-ending Valencia Grand Prix, a two-day post season MotoGP test began at the circuit on Tuesday.
Day one was marred by poor weather, which caused seven of the 21 riders to remain in the pits and prompted the Factory Yamaha team to send Valentino Rossi and Jorge Lorenzo to Aragon for day two.
Unfortunately, rain has been falling off and on at both Valencia and Aragon this morning.
As of midday, only three riders have recorded a lap time at Valencia. Rossi and Lorenzo have both reportedly been out on track at Aragon, but were then forced back into the pits by showers.
Moto2 stars Marc Marquez and Bradley Smith - due to make their MotoGP debuts at the Valencia test - did not set a lap time on Tuesday. The others to sit out day one were Dani Pedrosa, Cal Crutchlow, Shane Byrne, Danilo Petrucci and Lorenzo.
UPDATE: Bradley Smith left the pits for his first MotoGP laps, on wet tyres, shortly after midday.
Ben Spies, moving from Yamaha to Ducati for 2013, is not present due to recent surgery. His place is being taken by new Ducati test rider Michele Pirro.
Alvaro Bautista's Tuesday time was set on slicks, just before rain arrived.CLICK HERE
