Hypermotard 1100 EVO SP: The Desmodue Evoluzione Engine
The lightweight, L-Twin stands at the pinnacle of more than three decades of Desmo air-cooled development and its torquey power delivery has excited riders worldwide. The Evoluzione version is positively awesome and makes it the perfect engine to give its name to the Hypermotard 1100EVO SP.
The 1100cc Desmodue Evoluzione power unit uses a bore and stroke of 98 x 71.5mm, and its long list of refinements boosted its power to 95hp (69.9kW) @ 7500rpm with 76lb-ft (10.5kgm) of torque @ 5750rpm giving it outstanding power delivery, from grunting low rpms to the singing howl at redline.
The 1100's crankcases are vacuum cast using the same Vacural technology employed for the lightweight Superbike engines, a process that achieves significant weight saving and ensures consistent wall thickness and increased strength.
But the crankcases were just the starting point of the evolution. Apart from the magnesium alternator cover, the 1100 has a lighter crankshaft assembly by using an 848-style Superbike flywheel and the search for further weight reduction even went as far as using lightweight rare-earth magnets for the generator assembly. The result reduced the original 1100 power unit's weight by a staggering 5.2kg (11.5lb) and contributed towards making the Hypermotard 1100EVO even more agile.
Power gains have come not only from the new lightweight crankshaft assembly, but also from an evolution of the top-end of the Desmodue power unit. The cylinder head, not only improves lubrication and cooling performance, but also uses a redesigned inlet port shape for optimum flow and a modified combustion chamber shape for improved burn efficiency.
This improved efficiency is the result of a higher compression ratio and the change to a single spark per cylinder ignition managed by high-speed Siemens electronics.
Ensuring a sufficient feed to the higher compression set-up is a high-flow airbox intake duct and higher-lift valves for maximum volumetric efficiency.
The incredible valve performances of the Desmodue engine are only possible because of Ducati's unique Desmodromic system, where valve closure is activated mechanically. At high rpm it would be almost impossible for the valve to follow the steep closure profile of the cam lobe if it were relying upon a normal valve spring.
With the Desmo system, the valve is closed mechanically with the same accuracy as it is opened, enabling steep cam profiles and radical cam timings. This system is used on every single Ducati power unit including their world-beating Superbike and Desmosedici MotoGP engines.
In keeping with its extreme character, Ducati continue to use the 'dry' racing-style clutch for the Hypermotard 1100, the popular preference of thousands of Ducatisti the world over. The clutch and alternator covers are finished in gold for the 1100EVO SP.
Hypomotard 1100 EVO SP: Intense Suspension
Longer, black-bodied, fully adjustable 50mm Marzocchi forks have 30mm (1.2in) more travel and increase the SP's ground clearance by 30mm (1.2in), extending the SP's extreme cornering performance and providing a more track-oriented set-up.
Coated with a durable low friction, DLC (diamond-like carbon) black coating, the sliders enable the Hypermotard 'SP' to respond effortlessly to every minute variation in the tarmac, improving on its already impressive road holding.
The advanced 'SP' suspension is further enhanced with an Öhlins remote reservoir rear shock, renowned in racing as the ultimate performance choice. This incredible shock is fully adjustable for compression and rebound damping as well as spring pre- load, ensuring that the 'SP' is readily adaptable to every riding style and road or track it challenges.
Hypomotard 1100 EVO SP: Superior Brakes
With a bike as extreme as the Hypermotard 1100EVO SP, superior stopping power is fundamental, so world- class braking performance is assured by using the same Brembo Monobloc calipers as on Ducati's top Superbikes.
Machined from a single piece of alloy, the calipers achieve a higher rigidity and resistance to distortion during extreme braking, which not only delivers incredible braking power, but also provides an enhanced and precise 'feel' at the brake lever. The twin Monobloc calipers, each with four 34mm pistons gripping 305mm discs, guarantee spectacular braking performance.
Hypomotard 1100 EVO SP: Lightweight Wheels by Marchesini
Extreme riders know that one of the best ways to improve the handling and performance of a motorcycle is to reduce its unsprung weight by upgrading to superior lightweight wheels.
Even from a distance, the 5- spoke black Marchesini wheels with red pin-striping confirm the high performance of the Hypermotard 1100EVO SP.
Created from forged then machined alloy, both front and rear wheels are significantly lighter and create a lower moment of inertia and unsprung weight, resulting in improved acceleration and braking as well as quicker steering. Mounted to the lightweight wheels are Z-rated Pirelli Diablo Supercorsa SP tires.
Designed to deliver racing performance on the road, they give great feedback, are stable under severe braking and feature a sure-footed 'feel' when braking or accelerating is applied at considerable lean angles.
