Yamaha's MotoGP riders both suffered from a lack of rear grip and sliding at the Aragon circuit in the first race of the season. Lorenzo was plagued with rear traction problems and finished in fourth in FP1. Rossi was just a second under the top down in sixth position.
FP2 had an increase in track temperature, which further hampered the Yamaha pair. Lorenzo came in 7th with a 1'48.969s time. This was 0.501s odd of the leader Andrea Iannone of Pramac Racing.
Rossi ended the race in tenth with a time of 1'49.312s. That is 1.027s off of Andrea Dovizoso of the Ducati team who finished in first.
Rossi also commented:“We are using a completely different tyre to the rest of the riders. Valentino didn't like so much the hard front, I don't know if he tried the soft in the last laps but for me it was better with the softer option. Tomorrow we will do some more laps to see if it will be constant for the duration of the race. We didn't start in the best way possible, we are very far from the front, but the thing that worries us is that we are far from my ideal time here from last year so we have margin to improve. I feel great physically and mentally but the bike needs to improve a bit. We are going to test a different set up for tomorrow so I’m looking forward to continuing.”
Hopefully this will be a teachable moment for the pair and the Yamaha team. They can use this info as a stepping stone for better things next time.“Together with Yamaha and Bridgestone we decided to try the hard rear to understand if it’s good option but it proved difficult. At the same time I struggled with the front as I was suffering some under steer so we decided to try the soft front; that was not so bad. We got some important data for tomorrow because we tried all the combinations. We need to work a lot as we suffer with rear grip and corner speed. The bike is difficult to ride and I’m not fast enough so tomorrow we have to improve a lot.”
