To create an engine with this blend of brute power and supreme usability, Ducati carefully developed its cam timing with a particular focus on the valve overlap angle.
Defined as the period of crankshaft rotation (in degrees) during which both intake and exhaust valves are open at the same time, this overlap angle is set at 11° on the Diavel's engine - much less than the 41° used by Ducati's Superbike engines.
With its 152hp and colossal 91lb-ft of torque, the Diavel Testastretta 11° DS engine defines authentic Ducati Desmodromic performance.
Thanks to dual spark plugs, high-compression pistons, and revised injection spray targeting, the engine's torque curve is strong and smooth at low rpm, and remains so through a wide rev-range.
The system is equipped with a lambda probe for each individual cylinder, in order for the fuel injection to be optimised and managed autonomously via the large airbox.
The vertically stacked cannon silencers are equipped with catalytic converters that ensure compliance with Euro 4 standards, while the electronically controlled adjustment valve optimises exhaust pressure.
To keep the frontal lines of the Diavel clean, the technical solution of a highly efficient lateral radiator is placed on each side of the bike.
hese well-ducted units, located beneath the fuel tank, use aerodynamics to help draw cooling air flow through them and are assisted by high-flow electric fans when required.
This compressed intake charge is ignited by twin spark plugs in each chamber for rapid and even combustion.
Its personality is further enhanced by the forged and machined Marchesini wheels and the seat.
The standard equipment of the Diavel Diesel includes: hand brushed steel tank cover, passenger seat cover and flyscreen with weldings and rivets, black anodized side air intakes with weldings and red methacrylate covers with machined Diesel mark, leather seat and billet mirrors.
And after exiting the combustion chamber, a secondary air system burns off any residual fuel molecules, allowing a richer mixture to be used without increasing emissions.
As a combined result of these technologies the Testastretta 11° DS is the perfect base for the Diavel - full of character, and producing tremendous power that give unmatched acceleration, along with smooth and controllable delivery for cruising the boulevard at any speed.The power/torque values indicated are measured using an engine dynamometer according to homologation regulation and they correspond to the homologated data, as quoted in the Bike Registration Document.
