Production market and prototype racing have both been moving away from desmo for some time. Benefit of desmo is the ability to run huge valves and high rpm without valve float. Desmo was critical for old demodue (2-valve) performance engines. When everything switched to desmoquattro (4-valve), the importance of desmo took at hit, but rev ceilings were high enough to justify investment in desmo. Euro 5 could shift the paradigm. Ducati supposedly already abandoned desmodromic valve operation for the Multistrada. Haven't verified on the spec sheet, but it was widely reported a couple of years ago. Ducati to lose Desmo’ valves for 2021 Multistrada V4MotoGP ditched the screaming 800s for 81mm 1000cc engines. Rev ceiling is still high enough to justify using desmo or pneumatic actuation. Dorna regularly hints and reducing engine power output. Biofuel will knock the power down apparently. Reducing the rev ceiling could also be in the works.I think Ducati will probably continue with Desmo on all of their performance production bikes, since the competition version will surely run at higher rpm than the Euro 5 street bike. Standard Ducati models may ditch desmo to reduce cost and maintenance. In prototype racing, desmo is probably safe, even if they cut another 2,000-3,000 rpm off the top. The winds of change are blowing against Ducati's vaunted valvetrain technology, but maybe not hard enough?
