Agree on most of this, but being 15 km/h down is unacceptable for a MotoGP bike. The Yamaha grenaded at Misano. It was even much slower than the Honda.
I agree that Rossi couldn't do what Stoner did on the GP7 or any of the successor bikes. I recall reading Burgess summarising Stoner's incredible riding style - basically, a constant state of oversteer (which overcame the Ducati's reluctance to turn).
The 06 Yamaha had bad chatter issues, but they ended up reverting to an 05 frame at some point during the season which fixed the issues quickly. However, it did obviously grenade itself twice at Laguna and Le Mans.
I'll never forgive HRC for that stupidity with the "Evo" bike.
This is an old argument, sure the 2007 Ducati was fast in a straight line but the Aprilia cube was also very powerful to not much avail. The speed difference between the Ducati and Yamaha was particularly prominent at one track, either Turkey or China, where Yamaha couldn’t get their gearing right, and this has been taken by some to reflect how things were in every race. Stoner’s team-mate Capirossi who won 8 or 9 gp races and was a strong early contender for the 2006 title on the 990 Ducati GP06 hardly dominated the Yamahas on a factory GP07 either.
(EDIT I believe the engine which failed at Misano was the pneumatic engine under development for the 2008 Yamaha, which Rossi pushed Yahama to let him employ early to address the power deficit to Ducati and aid development of that engine for 2008, the championship which Stoner clinched 2 rounds later in Japan being pretty much over barring a season ending injury to Stoner. I don’t think there were any technical issues with the 2007 engine other than being a spring valve engine underpowered/unable to rev as high compared to the Ducati desmo).
