Ducati's Variable Timing Explained

Directly from the folks at Ducati, it's their DVT (variable valve timing) technology explained.





Ducati presents the first motorcycle engine with variable timing of both the intake and exhaust camshafts.

Named Ducati Testastretta DVT, Desmodromic Variable Timing, Ducati's new Desmodromic engine is the first in the world with variable timing on both inlet and exhaust camshafts, leading the way for a whole new generation of such engines. The innovative, new design overcomes an engineering gap in  current production motorcycle engines and underlines Ducati's strength in developing ground breaking engine and motorcycle technologies.

The variable timing system is able to continuously adjust valve timing, by acting independently on both the intake and exhaust camshafts. The system optimises engine performance throughout the rev range and in any operating condition, to guarantee the highest power, smooth delivery, muscular torque at low rpm and reduced fuel consumption. With full Euro 4 compliance, DVT sets a new standard in the combination of power, delivery and usability of motorcycle engines.
