This guy has one third place and is seventh in the standings, and some of you think he is ready for MotoGP? That's not realistic. Binder is ninth and Mir is seventh. Big deal.
How do we know more of these people don't ride liter bikes? While I think that it is nice that he rides a bigger bike, it is not racing a MotoGP bike. WSBK riders take time to adjust to MotoGP bikes. Look at all the wildcard failures over the years. Moto2 may prepare riders for MotoGP, Moto3 does not. I would want to see how he handles this year before signing him. Of course, his agent wants him signed - NOW. What the heck, it ain't his money, nor his body.
By-the-way, I did a track day with Stefan Bradl at Laguna Seca before his first ride there in MotoGP. He was riding a Fireblade, of course. So was I. He finished his career on a liter bike (Fireblade). I am not sure what good it did him.
