why did this season be difficult for the racing driver motogp

I think because this seasion used a new moto type, 800 cc. There's many thing to adapted to used this new moto style. The racer must adapted to their new moto, and the team must adaptes new style of engine that different from 900 cc and they must fine the best style for the best performance. I think it will be a good race to see. But I always hope valentino rossi will be reach the world championship again. Go!!!!!!!! Rossi go!!!!!!!!.:D:D::DD
