Seems a bit odd, that given Ducati have pretty much said they've written off this season now and are using it as a test bed for next year, that they are using a testing day today for the current set-up rather than running the 1000cc engine...
Honda & Yamaha both have their 1000 machines out today, it would have been a good opportunity to see how they compare against each other on next years machinery, and to see where improvements need to be made. So far they done most of the testing in private.
I'm sure there is method in the apparent madness, but I can't work it out!
