Ducati has unveiled a new cc Testastretta engine ahead of the EICMA Motorcycle Show in Milan, Italy. New Ducati Testastretta DVT V-twin engine revealed and detailed, features first ever variable valve timing (VVT) equipped in a bike engine. Ducati variable timing improves engines.

Each spark plug is managed independently, to optimise efficiency throughout the rev range and in all conditions of use. They had superb radial loads and axial thrust capacity, and thanks to their lightweight synthetic material cages they could stand extremely high rpm. It had a six-speed gearbox. The rest of the crankshaft layout remains unchanged. The Ducati and its variants including the R are similar to thebut the has a lower price, smaller, higher revving engine and slightly smaller rear tire.
Thanks to all these characteristics, the Ducati Testastretta DVT sets new standards for Ducati twin cylinder power units and introduces new, revolutionary parameters to achieve the best possible balance among maximum power, smooth delivery, low-rpm torque, low fuel consumption and reduced emissions, thus standing out as the most technologically advanced Desmodromic twin-cylinder engine on the planet.

It had larger displacement, larger valves, narrower included valve angle, better breathing through oval throttle bodies and butterfly valveslighter weight including magnesium valve coversand higher output than its predecessors. In other projects Wikimedia Commons.
ducatl At 94mm by The DVT system consists of an external housing, rigidly connected to the cam belt pulley, and an internal mechanism which is connected to the camshaft and can independently rotate inside the housing.
But those angular contact ball bearings are too expensive. The bore goes down from the old 81mm to 45mm. The highest peak testawtretta technology and Ducati design to reach the maximum perfomances. Each plug is managed independently to optimize efficiency in all conditions. This is a change more radical than it might seem, and it confirms what CEO Claudio Domenicali said a couple of years ago, when he made it clear that Ducati will proceed with two lines of engines—the then brand newand a constantly evolved Engune in various displacements.
P61 – P71, “Desmoquattro”, Author: The resulting enhanced fuel vapourisation improves combustion efficiency and ensures a smoother delivery. Equal parts writer, photographer, and rider, “JDawg” is a jack of all trades and even a master of some. The Ducati had a new engine called the Testastretta Evoluzione “evolution”. View the discussion thread. The Testastretta DVT is equipped with a Dual Spark DS system that uses two spark plugs per cylinder head, providing a twin flame-front that ensures complete combustion across tewtastretta very short period of time.
Thus, in the end, the new Pantah shared the 74mm x Fitted with a new, more powerful engine with slipper clutch, ready to unbridle a racing attitude. Luxembourg nl Luxembourg fr.

A secondary air system completes the oxidization of unburned hydrocarbons to reduce hydrocarbon and carbon monoxide levels.
The new crankshaft foreground of the Ducati comes from a new forging with more accurate counterweight profiles and the new, larger main-end journals. Thanks to this unique system, the intake and exhaust valves are closed mechanically and with the same level of accuracy as they are opened. Where it differs from variable valve timing, which is common in most cars, is that it works with their desmodromic valve system where the valves are lifted mechanically rather than on springs.
Happy New Year

The that powers the top version of the Monster has undergone the same structural modifications to work with the same frame-engine assembly. Only testastertta front one is used to mate the engine to the trellis frame, with a 12mm bolt. Inthe company introduced the Ducati model designed by Massimo Tamburini, with striking new bodywork that had aggressive lines, under-seat exhausts, and a single-sided swingarm.
Archived from the original on 2 April The cc Desmosedici engine is unique among production Ducati models for its use of gear-driven camshafts. It was retained because the other Ducati model powered by thethe Hypermotard, still uses the original trellis frame that is bolted to the bosses located on the crankcase, plus the front one and a rear upper one. This would cause an increased tendency of the crankshaft to flex and thus dump extra axial thrust on those magic bearings and the crankcase.

Quietly, the is bringing radical change to the family of degree V-twins derived from the original 8-Valve Desmo, which, in turn, was based on the Pantah that Dr. This is the new oil pump. The SuperSport is the road sporty bike that brings energy and sport emotion everywhere, from weekend to everyday roads.
The Ducati was designed by Pierre Terblanche, amid much controversy and criticism relating to the styling. Still, he did not want to use too much oil flow and pressure, so he decided for a hybrid solution for the Pantah: This translates into far less pulsating axial load dumped by the flexing crankshaft to the crankcase.
