Just saw a tweet from motomatters.com that Sachsenring might be hosting its last GP and might not be on the calendar from 2012.

3 US GPs in 2013 ?



Austin adds its name to the MotoGp Calendar, 2013 onwards

Ducati CF-Frame

Below is the link of my Understanding about CF-Frames on Motorcycles & it's history

Will Ducati be successful or not ... only time will answer.

^^ I guess the link you posted is incorrect. That is someone's FB profile

That's my FB id.

^^referring to the album about the CF frame??...., what about some practical benefits/shortcomings of the CF then??

Sorry for the OT but why is Jorge's M1 must faster on the straights? :O

K got it. Didn't check out your photos and was wondering how is that link related to CF frames
I guess you were referring to this photo in particular?

@Ranjith
More to do with slipstreaming than the top speed of the bike.
Also wondering if this can be related to the hot topic going on in motogp, the lighter rider vs the heavier one? The heavier rider won though

Sumit ... the link is just their to highlight as How CF-Frames have faired so far in the Different Classes of MotoGP until date. Further, I only have experience with Le-Man / Supercars & SAE-Formula race cars with CF. With Motorcycle Frame its a different ball game. The main focus in a race Motorcycle Frame had always been to get the maximum load concentration at the steering pivot which needs to absorb all the loads and as well exhibit some degree of flex to provide the required feed back to the rider. Look at the Pivot size & Load Bearing designs of the Modern Motorcycles against Old ones.

CF is more uni-directional in load applications unlike Metal ... kind of Concrete can take up huge Compression load but not that good with Tensile. It's the various layout of the honeycomb structure combined with the Carbon Mat layout plus pressure and backing time in the vacuum Auto-Clay that brings a huge variation in the final finished product.

It's far more easy with Metallurgy as the Industry has an huge understanding about it. Say a same material made out of SAE1008, SAE1010, SAE1023 Steel and so on can exhibit different characteristic properties with everything remaining the same. Even sometime for certain applications, after having all the necessary Metal inserts required for the application in a CF output does not save that much weight as regular Metal one. That`s why in F-1 some use Carbon Fiber Gear Cases and others Metal.

Further based on Engineering datas, properties and assumption its difficult to simulate and get accurate readings using CAE for CF unlike Metals. Further it`s far more time consuming and very expensive to make it in the first place and difficult to mend repair unlike Metals. Further Metals can be easily X-rayed for defects unlike CF. Even the Mighty Boeing has difficulties in perfecting their CF Composite Dream Liners.

in sbk commentry, this weekend, there were some talks on ducati tat was tested by rossi.. they said abt some new outward position for the rear suspension/swingarm.. but the downside was that it might be damaged in crash...
Any news on this ?

@TZ750: Thanks for the analysis I am no guru in this field but from what you said it looks like technology has still not evolved to make the CF chassis work as well as the metal ones, though CF have the weight advantage.
Still a long way to go...

How I hope that this is released in India(aware of reality though).....Imagine watching this in a theatre...in 3D..#goosebumps

@kingkong
holy shit,,tnx for that man!WOW!

I hope they mention/feature a bit of the God!-JOEY DUNLOP!
