MotoGP » Ducati won't ditch Desmodromic system

Ducati to stick with Desmodromic valve system for MotoGP engine.

Yam & Honda run pneumatic valve systems. Only way they could compete with desmodromic ability to open & close valves at higher rpms than conventional valve spring systems.

At least Ducati's run a system that has a real-world application on their motorcycles. The pneumatic systems have no real-world application I know of for Yam & Honda machines.
Which gives the lie to the fact that HRC & Yam are in MotoGP for 'development'. They are in it for the marketing platform which means they need to employ all means possible to make sure their bikes are up front.

If Honda & Yamaha truly wanted 'development' potential, then they'd want pneumatic systems banned so they could come up with something else that had a purpose away from MotoGP. But that would be handing back an advantage now wouldn't it?

"What Ducati should do is buy a Yamaka and Honda and copy it. Posted by XXX"
Great idea ! All they have to do is go to their local dealers, pay a deposit, and order one, no, wait, two of each. Mind you, they'd have to get in the queue behind Suzuki, Kawasaki, Birdy, BMW and about a thousand others. Trouble is, the desmo motor wouldn't fit the Yam or the Honda, and the desmo motor is the part Gobby wants to keep.
Curses ! Foiled again.

Gobby wants to keep the Desmo motor. Why ? Because it revs high and high revs mean high power. BUT, high revs also mean high fuel consumption, and the fuel limit is being dropped to 20 litres. So they will have to cut back the power to save fuel. Curses! Foiled yet again!
Ducati need to recognise that "traditional" usually means "out-dated", and that their "traditional" designs are not the optimum solution to today's MotoGP framework of Rules.
A Camel is a traditional design which is far better than a horse for carrying itself and its load great distances over sand. But you wouldn't enter a Camel in the Grand National, would you?
Ducati need to recognise - Horses for Corsa's .

@ Tetley. Your points just highlight the contradictions that make no sense in MotoGP.
A fuel limit supposedly so the Mfrs can develop fuel efficiency strategies. Yet rules that encourage stratopheric rpm's that are THE gobbler of juice.
The logic says then that MotoGP should introduce a lower rpm limit. But to do that means that all the exotic bits and materials aren't necessary to get a reliable and efficient motor -technology that is already well established does very nicely.
All of which says that either the fuel limit is plain daft, or the rev limit is too high. Having both seems senseless.

Will someone please tell Gobby that the engine needs new crankcases? Narrow the V/L angle and engine and swingarm mounts all in one go.
That's that sorted, can I have half of his salary?

In a world where both Honda and Yamaha set the rules, there is no way a company like Ducati can keep up.

General people are so damn ignorant in this regard, blaming Ducati by what? By trying to challenge the giants? By being honest?

After the single tire rule and now the RPM cuts I can say MotoGP is a game where the fix is in.

@ Gui. "MotoGP is a game where the fix is in."

Oh yes. Couldn't agree more, and have been saying this for ages. Fans seem to get distracted by the hype and what the factories spin-doctors sell (that it all about the exotic technology in the bikes, and that ultimate speed and lap-time is everything).
Fans buy into all this, and then seem to overlook that the actual result is pretty much a done deal before the off (any takers for anything other than a factory Honda or Yamaha on the podium steps at every dry race barring incident? No, I wouldn't either).
Fans have been conditioned to ignore the fact that the competition and the racing is dire, and to focus instead on the unimportant things that support Honda & Yamaha's agenda IMO.
