Discover moreThe Ducati Testastretta 11° is a twin-cylinder engine with a dual soul. It is very manageable and smooth at low revs, but with a torque that is always ready and able to unleash all the Ducati character when accelerating.
The Testastretta 11° is a liquid-cooled, 4-valve twin-cylinder with desmodromic timing system delivering an output of 111 horsepower.
11° like the valve overlap value, which primarily influences the dimensions of the cylinder head, hence the name Testastretta (which translates into Narrow Head).
However, this is an essential parameter for smoothness of operation, which is the main feature of this engine.
The valve overlap, in fact, defines the crankshaft rotation interval in which the simultaneous opening of the intake and exhaust valves takes place. The valve overlap has been configured at 11° for this engine in order to keep the exchange of fresh heat to the exhaust and combustion gases to the combustion chamber as low as possible, with the aim of achieving great smoothness of operation together with low fuel consumption and emissions.
The Testastretta DVT engine uses a variable timing system that acts on both the intake and exhaust valves.
Acting independently on both the intake and exhaust cams, it allows the engine performance to be optimised at all engine speeds and in all conditions of use, to ensure maximum power, smooth delivery, strong torque at low revs as well as low fuel consumption.
The Testastretta 11° is designed to be a stressed element and fundamental part of the chassis, and is a key component to guarantee the absolute weightlessness of the motorcycle.
The spirit of the XDiavel S can be fully expressed thanks to the Ducati Power Launch. This system can guarantee fast and safe starts thanks to the Bosch IMU which regulates the gas.

read moreThe Testastretta 11° and Testastretta DVT are exceptionally reliable and low-maintenance as the main maintenance intervals are less frequent. The oil change coupons are scheduled every 15,000 km, while the valve clearance check and adjustment is scheduled every 30,000 km.
Due to its inherent versatility, many models in the Ducati range are equipped with the Testastretta engine, both in the Testastretta 11° and Testastretta DVT versions.
