But whodathunkit would be from Ducati? http://www.ducati.com/en/testastretta_DVT/index.do

LOL - The worlds biggest PITA valve train just got more complicated.



Kawi has used the technology, but not on the SS/SB products ... Who wants to bet BMW will be next?

I have to agree with you Nerd, Ducati obviously only continue with the Desmo valves train for legacy reasons.
Probably effective in its day but when the Japanese manage to get a valve to close under spring load at 19000 RPM why continue with something so complicated.

Fit a ignition cut out quick shifter on your 1290 and you have variable valve timing also!
Warning it only works once!

Sorry couldn't resist....
