Pirelli Sportbike Tires
Less than a month since its unveiling, the Ducati 899 Panigale was launched this week at the Imola circuit in Italy. And just as its older brother the 1199 Panigale, the new Ducati “Supermid” uses Pirelli Diablo Rosso Corsa tires as original equipment, with a 120/70 ZR17 up front and 180/60 ZR17 out back.
The Pirelli Diablo Rosso Corsa are the most versatile hypersport tires available for use on the road and track, designed for naked sport bikes and modern faired motorcycles such as the 899 Panigale.
They embody the three founding souls of the Pirelli sport range, combined in one product: Diablo, the prestigious brand which Pirelli has been providing since the beginning of the new millennium, undisputed in the bike racing and hypersport world, Rosso the all-Italian Pirelli passion for motor sport competitions and Corsa; the most noble expression of power in race tires with undisputed performance.
Designed and developed based on the latest generation of powerful street bikes characterized by impressive technological equipment and electronics systems, Diablo Rosso Corsa offers incredible performance thanks to the continuous research that Pirelli conducts in the radial tire field for WSBK, the know-how acquired through vast experience in high performance segments, new techniques of road contact area optimization in any riding conditions and the use of its racing derived tread with multi-compound zones.
The Diablo Rosso Corsa profiles stem from World Superbike experience and were designed specifically to ensure optimum distribution of power in the road surface contact area. Therefore, the contact area with the asphalt is wider and all the power can be transmitted to the ground. Thanks to ICS (Ideal Contour Shaping) technology, born from the combination of the crafting skill of Pirelli engineers and the support of sophisticated computerised modelling systems, the Diablo Rosso Corsa provides excellent support in leans and a great feeling of confidence in turns at maximum acceleration.
The structure was designed to maximize the contact area at any leaning angle in terms of surface, shape and distribution of pressure, allowing the tire to reach exceptional levels of grip and stability. In fact, this tire uses the Pirelli EPT (Enhanced Patch Technology) patent derived from WSBK experience for an optimized road contact area at any lean angle on the road and on the track in order to ensure total riding confidence and power transfer to the ground in any condition.
The Diablo Rosso Corsa tread design has a patented solution which provides differentiation of longitudinal grooves from side grooves in order to reduce total land/sea ratio without sacrificing water dispersal capability. The tread groove wall angle ensures an equal water flow throughout the tire’s life because as the tire wears, the less severe angle
of the groove walls maintains consistent performance by avoiding tread edge deformation, along with a variable groove width for constant water dispersal until the last kilometer.
Furthermore, both the front and rear patterns were designed incorporating FGD (Functional Groove Design) technology which guarantees racetrack performance (closer to a racing Slick) and excellent control on wet surfaces.
In wet conditions, the front tire disperses the water by cutting through and allowing the rear tire to provide adequate grip. Grooves are located on the rear tire exactly where needed for an optimal balance between drainage and warm-up time with a 100-percent slick area at maximum lean to allow WSBK level grip, transversal grooves between the rear tire’s central and shoulder sections to quickly disperse residual water, ensuring maximum grip throughout wet corners and the central rib which guarantees more rubber on the ground for traction and straight line stability.
Among the new solutions developed for Diablo Rosso Corsa, compounds play a primary role. The front tire compound guarantees maximum support under heavy braking and corner exit. This concept of “high grip with high stiffness” was maintained by combining compounding tools (dedicated reinforced carbon black and resins) which increase tread life and wet safety. The result is a compound with both a racing and street soul.
The three zone compound on the rear tire, on the other hand, represents the ideal way to offer the best performance where required in very different conditions, such as racetrack and road. The differentiated compounds between shoulders and centre zone are the winning solutions engineered to give Diablo Rosso Corsa acing performance on racetrack and long lasting durability on road. Strong mileage is guaranteed by materials with high mechanical resistance in the central zone, while the high hysteresis shoulder compound gives steady grip response and incredible traction even at the highest lean angle.
In the central zone the compound is derived from Diablo Rosso experience, but even sportier. Pirelli engineers have inserted special resins and plasticisers optimized in terms of chemical properties and quantity to ensure the best balance between dry and wet grip.
Furthermore the compound mixture is cured with a dedicated process to increase wear resistance and thus mileage. Finally, the wide shoulders adopt a new softer compound developed and used in the WSBK arena. The 100-percent Carbon black compound is less rigid especially at mid-low temperature, allowing for a very quick warm up, and reducing the difference in temperature versus crown area for a very linear transition from one compound to the other.
And last, but not least, Diablo Rosso Corsa, as well as Diablo Rosso II, lets you personalize your tire with special rubber labels that can be applied to dedicated spaces on the front and rear sidewalls. Each rider can create a completely customized label for these spots on the web site www.pirelli.com and have them delivered directly to their door (service available in Europe and Australia).
