Pirelli DIABLO™ Supercorsa SP has received another recognition of its leadership in the segment of racing replica tyres for road use. It has been chosen by Honda, as original equipment for the CBR1000RR-R Fireblade and the CBR1000RR-R Fireblade SP (in 120/70 ZR17 front and 200/55 ZR17 rear), the much awaited supersport machines of the Japanese manufacturer. The top performing member of the DIABLO™ road family from Pirelli, now in its third generation, is confirmed once more as the first choice for high-performance motorcycles recently introduced on the market by the most prestigious motorcycle manufacturers.
The Pirelli DIABLO™ Supercorsa SP, currently in action at the Losail Circuit in Qatar, where the official press launch of the new Japanese supersport machine is taking place, are appointed as original equipment of the Honda CBR1000RR-R Fireblade and CBR1000RR-R Fireblade SP after they were chosen in 2014 to equip the previous SP model from this iconic Japanese brand.
DIABLO™ Supercorsa SP is a concentration of technology which draws from Pirelli’s racing experience and heritage as sole supplier of the Superbike World Championship since 2004, transferring sport technology to high performance street legal products. This street tyre, designed for bikers who have a sporty street riding style but also love the track, provides racing performance typical of track-only products, allowing the user to have a product that can be used in both arenas without compromise. Compared to the SC compound version, the DIABLO™ Supercorsa SP has a rear bi-compound solution in order to give increased mileage and more grip while leaning. EPT (Enhanced Patch Technology) has also made it possible to use 23% more soft compound in the shoulder area compared to its predecessor with 33% of the pattern extension on each side, guaranteeing better grip in mid to full lean. Finally, the polymers used for the SP compound helps achieve earlier warm-up and improved grip in all conditions.
The SP compound extends the mileage vs. racing specific compounds and withstands temperature variations for extended periods of time, typical of road duty and providing higher performance on wet surfaces. The stiffness and friction coefficient of the compound have been studied to allow a very high cornering precision supported by an outstanding contact feeling, on top of the well-known high stability and absorption behaviour of Pirelli Supersport tyres.
The performance of the compound is further enhanced by the aggressive single element tread pattern, which is the same in the racing SC tyres, which is repeated six times over the tyre surface. The result is that the “naked” area of the shoulders is 24% wider compared to the previous DIABLO™ Supercorsa, increasing contact area and grip. The longitudinal grooves, expanding from the central area to the shoulder, improve wear regularity, especially under severe usage and helps drain water.

The solutions adopted for the compound and the tread guarantee high levels of grip and traction, allowing the motorcycle to maintain high speed when leaning. This made it necessary to use a dedicated structure with greater resistance to deformation. This is why the DIABLO™ Supercorsa SP rear carcass is made from an innovative high module fibre, patented by Pirelli and developed in WSBK, with a considerably lower deformation ratio than the fibre normally used in street tyres. The result is a carcass that is more rigid, both at the centre and in the shoulder area. This provides greater resistance to the stress created by aggressive cornering or when accelerating early out of turns with the bike still in a leaning position.
