We have again put our hands on the Desmoquatro basic project, effectuating a set of modifications that make it a radically new motorcycle, named “Testa Stretta,” or narrow head.
The advantages of Desmo technology are added to those deriving from a revolutionary conception of the head - lightened by about 1.5 kg, thus obtaining an even lower center of gravity - which can be summed up as follows:
- Angle between the valves reduced from 40° to just 25° - from which comes the name “Testa Stretta” - thanks to a new geometric arrangement of the elements of the timing system, resulting in a more compact configuration of the combustion chamber
- Intake pipes and exhaust redesigned in a more rectilinear pattern
- Suction valve diameter increased from Ø 36 to Ø 40 mm
Other important innovations regard:
Considerably modified bore and stroke measurements - from 98 x 66 mm to 100 x 63.5 mm - to push the engine to higher rotation speeds
Single-injector injection system located “over the throttle” managed by the new ultra-compact and lighter Marelli 5.9 CPU
New engine-case design, produced using a sand-casting technique like the models used in the competitions
This resulted in the engine of the 996 R which, though rigorously the maintaining the 90° V-architecture of the Ducati twin cylinder tradition, marks a fundamental evolution in Desmoquattro thermodynamics, and opens new frontiers in high performance: 135 HP at 10,200 rpm accompanied by a torque delivery curve following a more steady and progressive course.
The Brembo Corse braking system completes the series of innovations: four-pad calipers, reduced-band brake disks. Overall, we have saved about 800 g on the non-suspended masses at the front, combining greater safety - more controlled pad wear, less roll-back in release - with increasingly more precise dynamic behavior.
The fairing has been redesigned, improving the Cx by 0.02, and is made of 100% carbon fiber. The frame-engine connection is stiffer thanks to fittings increased to Ø 12 mm.
The new 996R is definitely more powerful. It features an uncommon pick-up and its power curve never seems to drop. It is a thoroughbred born to win.
