"There is a big rumour circulating in the Italian media that Ducati may have abandoned their 90-degree V configuration for the engine in order to facilitiate more adjustment to weight distribution."

I hope that they get this figured out... Not sure that I like the idea of the aluminum twin spar frame but they need to do whatever it takes and it looks like they are...
Far better it is to dare mighty things, to win glorious triumphs, even though checkered by failure, than to take rank with those poor spirits who neither enjoy much nor suffer much, because they live in the gray twilight that knows not victory nor defeat."
Better put Fester on suicide watch if that rumour turns out to be true..... then again, given his powers of denial, it'll just be something else for him to ignore/discount.....
There has been talk staright from The Dude, when asked about V angle he replied nothing is beyond consideration. If you read about the Yamaha, they have an advatage that is not shared by Honda, in that the inline allows more options for weight transfer. Paraphrased, it means that any timing can be delivered to any config, but there are benefits of a lighter, more compact design. A gamit of options lends to more fine tunability...

You have a singular wit my friend.

You're going to wake him up!!!
He has been quiet lately
I hope it's true, I have been harping on about this for quite awhile. Honda found out in the 90's that as lean angle increased the 90* V4 couldn't deliver the front tire feedback that riders needed, and now that they are at 60*+ lean angle they need all the feedback they can get.
If they do alter the V angle I would hope they would just copy the Honda, that should make them competitive with Honda and Yamaha and capable of winning races.
Mercy call Rumor Control... Preziosi and Burgess both believe Ducati’s
trademark 90º V4 is not a concept that needs altering for its MotoGP
project... people forget the weight bias is aft for Bridgestones...
Quote Preziosi Jan 2012
“For me the angle is not a main issue. I think we could design a great bike
with 90 degrees and a great bike with a smaller angle. There are some
advantages with a smaller angle and some disadvantages, especially for this
displacement. This displacement is obtained just increasing the stroke
because the bore is more or less similar to the 800, so the engine becomes
higher if you close the angle. There are some disadvantages in doing that if
the stroke is very high. But if the engine is higher it isn’t as long, so it is a
compromise.”
Quote Burgess Jan 2012
“The 90-degree is a very good engine although perhaps a little more difficult
in the packaging but not something that I would be afraid of. If you can
package a V4 the right way it's the best engine. If you spoke to most of the
engineers in the world their choice of engine would be a 90-degree V. The
packaging issues are not impossible to overcome and it has won races in the
past, so no one can say that is holding us back.”
I would not be at all surprised to see a 60-75 degree or so V4 out of Ducati, for the improvements in packaging, but this needs to be balanced against the possible need for a power-robbing balance shaft.

If they change everything, they will have more excuses when they are still buried on the grid when the season starts. Then they can blame Honda's budget as the reason for their winning and not have to justify their own shortcomings. Either way, no one will question the fact that they have gone significantly backwards during Rossi's watch. Just burn the Factory down and save everyone's hide.

In the Panigale, they kept the 90 degree included angle between the cylinders, but they rotated the V from the more horizontal "L" configuration, so that the front cylinder is less horizontal, to make the length of the engine much shorter and allow the engine to sit closer to the front wheel.
In the MGP, the rumour is that the included angle of the V is narrower now, than the previous 90 degrees, for a more compact V engine, like the Honda and Suzuki have always been. The disadvantage is increased vibration and possible need for power-robbing balance shaft. Additionally, the MGP engine has always been a more traditional V layout (both cylinder banks rotated more vertically around the crank) than the street motor angles, to make it shorter, so they couldn't do much more with rotation now, and (apparently) may have closed the included V angle between the cylinders.

hmmm, motomatters reports that the banks of cylinders may simply be rotated some more, not the included angle of cylinders reduced......so clearly much speculation going on.
The motor is 999cc, makes 15HP more than the 800cc and achieves 360 km/h (224 MPH) from around 250 HP.
