Ducati Diavel

Weighing just 463 lb (210kg), featuring a powerful sophisticated design and offering a massive 162 hp that is managed to perfection via the three Riding Modes, the Diavel is an utterly spellbinding bike that only Ducati could have come up with.

Captivating, muscular and innovative beauty. Seductively agile and manoeuvrable. An irresistible 162 hp adrenaline rush that's always under your control with three riding modes and the Ducati Riding Safety Pack (ABS + Ducati Traction Control). You'll steal every look even when you disappear in an instant. This is the magic of Diavel.

Diavel concept

The Diavel project was born when Ducati designers applied their wish-list of bike “basic instincts” to a blank canvas. With a “what if?” approach to creating a dream bike, they sketched inspiring shapes which became a lower and longer motorcycle. “The challenge of building a muscular silhouette over a pure-bred competition motor had to be met with determination and a delicate touch, and the result is a frontal area that looks like a power athlete on the starting blocks,” explains the team at Ducati Design responsible for the project. “With the front wheel kept close to the Diavel’s body and using the short tail of a sport bike, we were able to blend this muscular design with a chassis that matched.”

Diavel design

The stance of the Diavel is that of readiness, dominance, and confidence bordering on superiority. With lateral radiators adding muscle to its broad “shoulders,” which then taper down across the engine and into the belly-fairing with oil cooler, the athlete took shape. A massive 240 section rear tyre was a perfect example of how Diavel designers used a no-compromise attitude when applying their wish list of features. The sheer width of rubber communicates so much power and style that the R&D team vowed to find a way to make it handle - even if they knew the image would send a seismic shock through the industry. The Diavel is a true Ducati, born from a passion for motorcycling and designed to deliver authentic Ducati performance in every respect.

Engine
Testastretta 11°
The Diavels heart is the Ducati Testastretta 11° - developed directly from the incredibly powerful, world-beating race engines of Ducati Corse. Ducati’s Testastretta 11° harnesses the immense power of the Superbike engine and makes it smooth and adaptable, a massive step forward in balancing high-performance with an enjoyable ride. For an engine with brute power on tap when needed and smooth, user-friendliness available for an effortless and comfortable ride, Ducati revised the configuration of the cam timing with particular focus on the valve overlap angle. The overlap angle is defined as the interval of crankshaft rotation, measured in degrees, during which both the intake and exhaust valves are open at the same time. This overlap occurs between the end of the exhaust stroke and the start of the intake stroke. High performance engines, which are subject to compromising smoothness for extreme power delivery, use high values of this parameter in order to benefit from the pressure waves to improve engine performance by maximising volumetric efficiency. On the Testastretta 11° engine, this angle has been reduced from 41°, used in the Testastretta Evoluzione engine which powers the 1198, to 11°. As a result, the fresh inlet charge flow is less compromised by the exiting exhaust gases, resulting in a much smoother combustion in addition to improved fuel economy and lower exhaust emissions.

Ride-by-Wire
The Ride-by-Wire (RbW) system is an electronic interface between the Diavel’s twistgrip and engine, which configures an ideal power response depending on the riding mode selected. The twistgrip no longer has a throttle cable connected directly to the throttle body butterflies, but instead delivers a signal to a control unit, which in turn operates the butterfly opening electronically. The RbW system uses three different mappings to regulate the power delivery: 162hp with a sports-type delivery 162hp with a progressive delivery suitable for touring 100hp with progressive delivery for city use

15,000 miles between major services
Constant investment in quality by design, advanced materials and engineering techniques have enabled the distance between major service intervals (valve clearance check) to be increased to a highly competitive 15,000 miles. This has been achieved with the introduction of new valve seat materials, improved combustion efficiency and temperature management designed into the Testastretta 11° engine.

Twin lateral radiators
The technical solution employed for keeping the frontal lines of the Diavel clean was to place two highly efficient lateral radiators on both sides of the bike. These well-ducted units, located beneath the fuel tank, use aerodynamics to help draw air flow through the radiators and are assisted by high-flow electric fans when required. The design combines form and function to enhance the muscular shape of the bike.

Slipper clutch
The transmission features an oil bath clutch with “slipper” function and super-light feel at the lever. Its design uses a progressive self-servo mechanism that presses the plates together when under drive from the engine, enabling the reduction of the clutch spring rates. This results in a much lighter clutch lever at the handlebar, ideal in stop-start traffic or during long journeys. When the drive force is reversed (over-run), the same mechanism reduces the pressure on the clutch plates, enabling them to provide a race-like “slipper” action, which reduces the destabilizing effect of the rear-end under aggressive down-shifting and provides a much smoother feeling when closing the throttle or down-shifting under normal riding conditions.

Exhaust system
The massive 58mm (2.28in) section exhaust headers lead the 2-1-2 system through power-enhancing equal lengths 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 stylish cannon-style, vertically stacked silencers carry catalytic converters to provide Euro 3 conformity and electronically controlled mid-section valve optimises exhaust pressures throughout the rev-range.

Power and Torque
With its 162hp and colossal 94lb-ft (127.5Nm) of torque, the Diavel Testastretta 11° engine is all about authentic Ducati Desmodromic performance. The revised intake and exhaust ports combined with radical adjustment of the cam timing have enabled Ducati to achieve a fantastic torque curve at low rpm, which remains strong through a wider rev-range. The increase in bottom-end torque is managed by Ducati’s Ride-by-Wire (RbW) system to considerably enhance the Diavel’s effortless ridability, while ensuring plenty of power remains on tap for high-rpm riding.
