Ducati to ditch desmo valves on most of its bikes
Think Ducati engines and desmo valves are the immediate connect. For the uninitiated, this is a different valve control system where instead of conventional valve springs, the valvetrain is controlled via two cams and two actuators that individually open and close a valve. This system has big benefits in creating high rpm power, but the downside is the dreaded "desmo" service. Mid-level Ducati motors will drop the desmo valves Desmo valves will remain only on the highest performance engines Work on this shift is already in progress What is a Desmo service, and why is it feared? The desmo service is essentially a big service where valve clearances are inspected and things like timing belts, air filters and spark plugs are changed. This service needs to be done between 24,000km and 30,000km depending on the bike and it can cost a serious amount of money. Ducati is aware of the desmo service’s infamous reputation and is working towards moving away from this system.
