Ducati has announced that it has fitted variable cam timing to the Testastretta 1198cc motor, currently found on the Multistrada.
Called DVT —Desmodromic Variable Timing — the variation of timing is achieved by allowing both camshafts and cam belt pulleys to move relative to one another, an action controlled by sensors that determine engine speed, throttle position and conditions and adjusts the timing accordingly.
Ducati claims that the result is a maximum power output of 160 hp at 9,500 rpm  (up 10 hp) and 100 ft-lbs of torque at 7,500 rpm (up 9 ft-lbs). But the variable timing is said to also boost mid-range torque as well as improve fuel economy and reduce emissions to boot.
No official word on where the new motor will end up but it seems likely that the 2015 Multistrada will get it first.

Variable valve timing?
Although variable cam timing is nothing new (Kawasaki use it in its 1400GTR) , it’s relatively unknown on motorcycles and allows for the valve timing (opening and closing of the intake and exhaust ports) to be optimized for different rpms, allowing for increased valve overlap at higher rpms.
This technology enables the engine designers to either maximize power deliver, torque characteristics or fuel economy throughout the rev range – something that is a compromise in fixed timing motors.
