DIABLO ROSSO CORSA II FEATURES
RACING PROFILES
The profiles of DIABLO ROSSO™ CORSA II derive directly from those used in racing. The profile of the front tyre features a racing-derived, multi-radius design that enhances handling, inviting the rider to lean in earlier and facilitating quick changes in direction.
Compared to its predecessor, the DIABLO ROSSO ™ CORSA, the profile of the new tyre is broader and wider, providing a larger, more stable contact area for the leaning motorcycle. The rear tyre follows the same pattern and similar geometry ensuring a harmonious feeling from the pair of tyres.
The tread design:
One of the strengths of the DIABLO ROSSO™ CORSA II is the tread pattern — an evolution of the DIABLO ROSSO™ III — optimised to provide performance similar to that of slick racetrack tyres and ensure superb control in street riding. The uninterrupted "flash" design is an effective solution in terms of tread compactness, full/void ratio, groove orientation and water drainage.
DIABLO ROSSO™ CORSA II offers a wide slick zone on the shoulders and thus guarantees superb grip as well as precision and stability at high lean angles. Wide, interrupted grooves prevent tread deformation, enhancing overall compactness and, consequently, ensuring better, more uniform wear under both road and track conditions. The result is a highly stable tyre.
The full/void ratios applied on front and rear tyres of the previous model have been modified and the result is greater surface in contact with the asphalt at various lean angles and thus better overall grip under all conditions.
The central portion of the "flash" also increases the number of grooves on that portion of the profile used when leaning on a wet surface — in conventional road use this angle generally ranges from 10° to 30°. The shape of the grooves has been specially designed to achieve rapid warm-up and excellent drainage of water under wet conditions. The surface between 30° and the shoulder is the area affected when leaning; here, on the DIABLO ROSSO™ CORSA II, the tread grooves have been progressively reduced until the area is completely slick. No grooves means no deformation and thus utmost stability.
DIABLO ROSSO CORSA II STRUCTURE
DERIVED FROM RACING
The solutions adopted for the compound, tread and new profile, significantly improve grip and traction, making significantly higher speeds possible in lean. However, this means that the tyres are required to absorb greater dynamic forces and hence greater stresses. To address this, Pirelli employed a new structure - derived from racing - but with slightly higher structural rigidity in comparison to its predecessor so as to adapt perfectly to the stresses without forfeiting comfort.
To achieve the full potential of DIABLO ROSSO™ CORSA II, a high-modulus Lyocell fibre casing was adopted for the rear tyre, a casing with a significantly lower deformation ratio than that of the fibres normally used in street tyres. The high-modulus Lyocell fibre casing is an exclusive, patented Pirelli technology developed through the company's participation in the FIM Superbike World Championship.
The result is a carcass that can better withstand the stresses generated when aggressively entering a corner or when accelerating sharply while the motorcycle is still leaning. The new casing also responds perfectly to roughness in the asphalt, ensuring a good degree of comfort and helps latest generation motorcycles achieve better performance when the rider shifts their weight between front and rear, a characteristic more evident at greater lean angles.
The radial casing offers a good degree of stiffness also for the front tyre, supporting the profile and enabling the blend to achieve superb grip on the asphalt. It is made of high performance Rayon, which maintains shape even under the stresses generated by acceleration forces and full loads.
The combination of front and rear structures works optimally with the latest electronic control systems, ensuring the best performance and delivering higher level of confidence and control to the rider.
