Why didn't you become an engineer if you think you know more than VR and JB??!!

For sure VR and JB know better than anyone you can imagine. and for that #99 of Yahama, even today people remember Yamaha with its yellow #46 on it, the number that made it what it is today !! for over a year Ducati have only tried 2 chassis and only a single swing-arm, I remember Honda tried 12 different chassis only for Pedrosa and god knows how many millions of dollar they spent to be what they're now. Even with PM's money ducati can only spend less than 40 million dollar compared to astronomical half a billion dollar budgetof HRC Honda. Get it right or don't post silly comments !!

@ Sam, I like it red not yellow, same as red wine.
JB and Rossi do not know it all better then everybody. If they knew more they would succeed last year already. At least one thing they know, is that they have no idea about any design deviating from the traditional Japanese bike. If Rossi and JB will take over Boeing the new 787 will go back from CF body to iron taken from the titanic... As steel is the most know construction material.

Let me teach you guys something about the CF frame Ducati, it was a pile of junk, Casey won his championship aboard a steel trellis Ducati,he was never champion on the CF Ducati. I'm an engineer and when it comes down to materials I know a thing or two, but for all the wonderful things we could say about carbon fiber one thing remains a constant, and that is that it's very hard to work with. Then you have the issue with feel, every material has it's own unique characteristics. For a race car it might be the best thing out there, but bikes are a different breed. A riders success depends on the feel he gets from his bike, if the brakes, the tires, the chassis or engine are performing to his liking he will not perform at his best. Period, the end.

@Rejectdonkey

Did you that 787 is behind schedule just because of the CF structure, know this for a fact my nephew works for the company, he's a mechanical engineer for them. Lol. Check your facts before you post.

No use Rayrock.

That wouldnt matter to anybody.
Some dont understand that Stonner won on a Ducati. When the changed to CF, Stoner crashed a lot, cuz he wasnt feeling the front , so he didnt know the limit he could push.
Bottom line, Stoner had to change manufacturers to win the WC.
I do have respect for him(rather, everyone racing)
Hope Ducati get things sorted out.

IMO, the test result arent exactly what they expected. But we'll only know this at free practice

Rayrock - you just posted on exactly the topic I've been wondering about. Why the material change? I'm not sure I agree with "Period, the end" on this.

I'm an engineer as well, and on the surface it seems CF offers significant advantages for this application. That said, I understand the feel argument (different structural stiffness/damping).

However, can their performance really be attributed entirely to rider feel, or are they simply not finding advantages for the (likely significant) extra cost while the root(s) of their problems still lie elsewhere? And if they're not realizing advantages, could that be attributed in part to design inexperience with CF for a two-wheeled application?

And it is not he first airplane not being in schedule, CF or Al. We shell see in 4-5 years what is going on with CF. Honda have issues as well regardless that the bike is made of Al.

If ducati tinck that the solution is to dream with fenomanel and expensive parts to reach the top with the telemetry and the results telling they are wrong Ducati will not pass of a bunch of youngers enginers that tinck they no it hall and they know nothingh.. Now if Ducati open there brains and star to lesson to rider maybe they will get to the top more fast that they expect.. If Ducati allways says ohhh where are so small compared tp japonese we are so law on budget!! Why its allways Ducati that have to take there riders into psicilogial treatments?? Iven Melandri perform well on one Secund hand Kawasaki with one Hayata Kawasaki one bike from last year kawasaki and also know to be very agressive..
