Ducati confirms carbon fibre swingarm

Ducati has confirmed to Crash.net that the new swingarm used during the Qatar MotoGP night test, which concluded on Tuesday, is made of carbon fibre.

Ducati's Desmosedici GP9 is already the only MotoGP bike to feature a carbon fibre chassis and the move to a carbon fibre swingarm further separates the Italian machine from its Japanese rivals.

Ducati's five MotoGP riders all claim to have felt a clear improvement in stability from the carbon fibre chassis, but factory riders Casey Stoner and Nicky Hayden avoided being too specific after debuting the new carbon fibre swingarm at Qatar.

“We confirmed the good feeling I had yesterday [Monday] with the new swingarm, although we still need more time to work on it and that's what we'll be doing at Jerez,” said Stoner, after finishing the Qatar test fastest of all by almost one second.

“I got a good feel for the new swingarm straight away but we still have work to do and we need to make more comparisons with the previous version before drawing definite conclusions,” added Hayden, who was fifth on the end of test timesheet.

The original Desmosedici GP9 swingarm is made of pressed aluminium.

The final pre-season MotoGP test of 2009 takes place on March 28-29 at Jerez.


WOW

ducati are really working hard on evolving the machine and doing an awesome job IMO

Does that table also have a v4 by chance?

Not enough lateral flex, IMO!

Hmmm, maybe not, but how about a carbon fibre backbone for pedro?

I think Peders may need it more.

i hope you hook a big croc one day and he takes a bike out of your sorry ...

hex.


fair play to ducati, a real prototype bike

got a feeling any weight saving will be in vain when the rider ,bike combined weight rule is introduced.

yeah but Rog. they did it for stiffness ( and tuneability of stiffness of the CF) .... not any weight savings. Same as why they did the frame I suppose"

how much of a saving in unsprung weight will the cf swingarm have? that will surely have an impact as well as the "tuneability" of the flex etc..

I don't think I get what you guys are getting at?

so are you saying it may make them too light?

well if thats the case they just add ballast weight don't they?

Spot on. 2/3 of the swing arm is considered as un-sprung weight, this is where you get the bike to handle better. There going to have to build flex in somewhere tho. you have to admire ducati for trying these new exotic things

Ducati may now be in a better position than the big japanese firms to experiment with engineering, partly because their organisation is smaller and more flexible intrinsically as it has always been, but also because I understand with the current recession/depression the culture in japan has become quite radical, and expenditure on frivolities like racing is frowned upon. On the other hand ducati's whole reputation and ability to sell idiosyncratic bikes at premium prices is based on racing; idiosyncrasy is something I very much approve of btw.

My engineering knowledge is scanty, but I was also under the impression that reducing unsprung weight was good for handling particularly in racing applications; that is what the guy who sold me the enkei racing wheels for my car told me anyway

There's no mention of weight loss .... but they did mention that there old swingarm was a pressed aluminium one ....... so I think there would not be a huge difference in mass. But who knows .... could be an ancillary benefit. Whatever the case Stoner said that that "hot" lap was done on the new CF swingarm ........ so its working.

I think a lot of Ducati's quick success has been due to the way Ducati Corse is run. Unlike HRC or other racing companies, Corse has the ability to do whatever they want as long as they stay within budget. Staying on budget isn't difficult for Corse because it is a small operation fueled by dollars from American mega-sponsors like Marlboro and Xerox. I believe they also get most of the proceeds from Corse branded products as well.

Furthermore, most people I know who've met Domenicali say that he and everyone else at Corse are completely intransigent. Rossi has gone on record as saying that Honda and Ducati are alike in that sense, but I think Ducati is able to succeed where HRC have failed because Ducati have less internal politics.

No honor resignations, no cultural embarrassments, no BS press releases to save face. Most importantly of all though, Ducati proved they are willing to win even if it means an Italian is not the #1 rider.

Ducati are simple: "Cazee go more faster all the time". As long as they stay focused on the main goal, they will succeed, imo. If they get bogged down in politics, they will turn into the HRC we see today.

Corse won't start having serious problems until they have to transfer power from Domenicali to the next generation. If Domenicali is not ready to go, it will be a bloodbath.

I just posted this link in the Qatar test thread, but it seems more relevant here

http://www.motogp.com/en/news/2009/Stoner+reviews+Qatar+test

"'We still managed to try a few things with the electronics – some of them good and some not so good and we confirmed the good feeling I had yesterday with the new swingarm, although we still need more time to work on it and that’s what we’ll be doing at Jerez,' confirmed the Australian, who can expect to be in even better condition for that next test in the south of Spain."

"Stoner fell at turn two of the Losail International Circuit shortly after recording his mercurial time"

Ha ha! Those motogp writers are so creative

If they came out with a carbon Hossack type front end I would go completely bonkers.
