It would be interesting to hear why he thinks this, as we have seen a rider like Marquez dominate lowers classes with no electronics. all I know is the more spec things get with electronics, the more Marquez seems to widen the gulf between himself and the other riders. A lot of people were bleating about how Marquez and Honda would struggle without their proprietary electronics and he is running off and leaving the pack at will without it. Now you have people bleating that the spec IMU will bring Honda down because they are assuming it is them and only them that have figured it out. I would be willing to bet that Marquez takes another step in his domination with the spec IMU as it will further highlite his skill level over the other riders. I think Stoners argument holds water against the likes of Pedrosa, Dovi, Lorenzo, but I would pick Marc straight up in a head to head bike race against Rossi no matter what you put them on.
