Pirelli Introduces New SC3 Compound For Its Diablo Superbike Slicks
The new SC3 solution, available for the front and the rear is the longest lasting of those present in the Pirelli DIABLO™ Superbike 2016 range. This solution was developed after years of experience acquired in the FIM Endurance World Championship and from the many victories in competitions such as Le Mans 24 Hours or the Bol d’Or. It is designed for endurance racing but also for track day riders, which a high level of wear resistance and long lasting performance is needed.
When compared to the SC2 rear, which is similar in characteristics, the SC3 offers greater durability and more constant performance in all ranges of use, at the cost of outright lap times. On the front, the SC3 is versatile and offers constant performance. Compared to an SC1 it offers longer mileage but at the cost of grip and lap times, while if compared to the SC2 it continues to offers better mileage. The new SC3 is an excellent solution for endurance competition and track day riders and for example, Northern Europe Championships, where these new tires are less likely to tear with the cold During the year it will also be appearing in the MOTUL FIM Superbike World Championship but only as a front option: the circuits the World Championship are raced on, the length of the races and the temperatures normally encountered on these occasions do not in fact make it a valid solution for the rear where, in almost all cases, riders prefer the higher performance SC0.
SC3 – Super Hard: This is the new entry for 2016 and the out-and-out sturdiest solution of the range. Developed above all for endurance activities it can however be used in all national championships where a compound particularly resistant both to abrasive asphalt and/or to low temperatures is needed.
· SC3 – Hard: New for 2016. Compared to the two previous solutions it certainly offers a higher mileage while remaining versatile. This could prove the best solution for the front tire on particularly demanding circuits.
