Maverick Viales and Valentino Rossi were back in the Movistar Yamaha MotoGP box today for the first two free practice sessions ahead of Sunday's Gran Premio Movistar de Aragn, but it wasn't all smooth sailing. A search for a good set-up at the wet MotorLand Aragn track was the main challenge for the riders, who secured 17th and 20th place respectively.
