2015 Ducati Diavel Titanium

Testrastretta 11°

The Diavel's heart is the Ducati Testastretta 11° Dual Spark (DS) - developed directly from the incredibly powerful, world-beating race engines of Ducati Corse. Ducati's Testastretta 11° DS harnesses the immense power of the Superbike engine and makes it smoother and more linear, combining high performance with an enjoyable and perfectly manageable ride.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. As a result the fresh inlet charge is less compromised by exiting exhaust gases, resulting in smoother combustion, improved fuel economy, and lower exhaust emissions.

The massive 58mm (2.28in) section exhaust headers lead the 2-1-2 system through power-enhancing equal length pipes that enable the Diavel's efficient power delivery. The engine management system dedicates a lambda probe to each header, providing precise fueling via a large airbox, while the new slash-cut vertically stacked exhaust silencers carry catalytic converters to provide Euro 3 conformity and feature an electronically controlled mid-section valve to optimise exhaust pressures throughout the rev-range.

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. These 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. Their shape integrates seamlessly with the overall design, combining form and function to enhance the muscular presence of the bike.

The redesigned, more comfortable seat offers more room and has a low height of 770 mm, which allows for extended hours of riding pleasure and makes the Diavel accessible to a wide range of riders. A relaxed handlebar position sits naturally in the rider's reach, ensuring full control and comfort with the unmatched coolness of cruiser style.

The Diavel uses 50 mm Marzocchi front forks with fork legs finished in low-friction diamond-like carbon (DLC). These forks are fully adjustable for spring pre-load, compression and rebound damping.

The forks are equipped with slash-cut triple-clamps - the bottom yoke in die-cast aluminium and the upper in forged aluminium - with a rubber-mounted tapered alloy handlebar clamp. With a 28° steering rake, 130 mm trail and 24 mm offset, this set-up provides a sure-footed yet agile front end for incredible handling.
