In the last race at Assen they showed a nice slo-mo clip of Rossi, Lorenzo, and then Stoner going through a chicane. You can clearly see Rossi and Lorenzo going through it smoothly, whereas when Stoner went through the chicane.... he came out of it with the front wheel up in the air, steering with only the back tire. Didn't know if anyone else caught that, if only there was a clip of it somewhere out there, or for those who recorded the race can go and check it out.
Seeing as how Assen is quite a technical track, it doesn't suit the Ducati at all.... which showed with Stoner's 3rd placing. I guess where I'm going with all of this is that the Ducati is a very unrefined bike compared to the Yamaha, so for Stoner to be competitive on that machinery just goes to show how good of a rider he really is.
