The new Pirelli DIABLO™ SUPERCORSA SP is the ultimate expression of Pirelli technology, its racing soul approved for road use. In fact, the DIABLO™ SUPERCORSA SP is the third generation of Pirelli’s highly popular race replica tire featuring tread design, profile and structure that are nearly identical to those of the racing tires which are used in those competitions that, according to regulations, require the use of grooved and not slick tires.
The new DIABLO™ SUPERCORSA SP has been developed through Pirelli participation as the Sole Tire Supplier for all classes in the FIM World Superbike Championship.
The DIABLO™ SUPERCORSA SP has a new racing profile. More specifically, this is the same profile Pirelli uses in its FIM World Superbike Championship DIABLO™ SUPERBIKE slick tires, a tire that achieves new levels of maneuverability and grip both on the track and on road.
The 200/60 ZR17 rear tire has been completely redesigned and adopts the same profile used in the slick tires. Compared to the 200/55 ZR17, the new profile is 9 mm wider and its overall diameter is 16 mm greater. Much of this larger diameter is used in the tread area that, thanks to the increase of the cord, allows lean angles never reached before and a greater footprint.
All this improves maneuverability and ensures a wider contact area which, in turn, means increased grip, stability and trajectory precision, not only when leaning into a bend, but also when entering and exiting the bend, i.e. when the rider is still braking or has started accelerating. With this technical solution, the tire achieves a new degree of grip at maximum lean angle and, since it maintains the same radius at the center of the profile, it does so without forfeiting the manageability typical of the 200/55.
The front profile has been enhanced and is now 2 mm wider than that of the previous 120/70 ZR17. It has been perfectly balanced to work in unison with the rear tire, thus guaranteeing excellent handling and good support in the bends. The advantages are the same as those achieved on the rear tire but with the added benefit that, thanks to its wider area of contact, less stress is applied on the compound.
The casing for the new DIABLO™ SUPERCORSA SP has been derived directly from the DIABLO™ SUPERBIKE slick product. The rear tire has a pure radial carcass, the front is also radial but with an angle of the carcass plies optimized for road use. In particular, these insights have been aimed at improving stability at high speeds and on long straight stretches such as on highways.
The front tire is a mono-compound, a solution that allows rapid warm-up and a steadfast grip in any situation. The thicknesses of the compound on the tread band have been optimized in every area from the center to the shoulders using a new high automation Pirelli process that optimizes the amount of material to be applied with utmost precision.
The rear tire is a bi-compound and for the first time ever in a tire approved for road use, Pirelli decided to use a racing blend developed in the FIM World Superbike Championship. Using the Enhanced Patch Technology (EPT) it proved possible to use a very soft compound on the shoulder. By using new polymers for the compound in the DIABLO™ SUPERCORSA SP it was possible to achieve even faster warm-up and an even better grip under all conditions while keeping consistency of performance.
When compared to its predecessor, the DIABLO™ SUPERCORSA SP has a new, optimized eight-step tread pattern, a pattern that repeats eight times over the entire tire surface.
