Enhanced Patch Tecnology

EPT is the ultimate technology developed by Pirelli to keep the bike in extraordinary touch with the road surface. Its application to DIABLO ROSSO makes this new tyre offer a level of excellence never seen before for a road product.

EPT (Enhanced Patch Technology) optimizes in all riding conditions the shape, area, and the pressure distribution of the contact patch.

The continuous development of Pirelli tyres in the World Superbike championship, the know-how acquired by endless test of Diablo on the new road bikes and the cooperation with the bike manufacturers, made possible for Pirelli to find further technical areas of improvement for a product that was already the benchmark in the segment.

Pirelli development has been focused on latest generation of machinery, characterized by quite different power and torque curve delivery across the entire rev range. They require that even more power be transmitted to the ground. New generation of chassis, with higher rigidity, allow greater responsiveness and benefit from an optimal balance of grip and handling; ergo the front delivers faster corner entries and greater feedback allows more security.
The latest generation of electronics and rider aids (i.e. slipper clutches) complete the evolutionary benefits. All this improvement passes through the tyre; all the tyre tasks pass through the contact patch.
The success of Diablo Supercorsa is confirming that an improvement of the contact patch behavior can give benefits far away from contribution of every other single component, like a compound. Improving the contact patch requires a specific and integrated tyre design as many variables influence it: the dimensions at different angles, the tread cuts inside it, the load distribution, the rigidity.

This is the basis of the Pirelli EPT (Enhanced Patch Technology): the entire tyre set components work in coordination to keep perfectly in touch the bike with the ground. EPT technology is coordinated with the Functional Groove Design (FGD) that optimizes the tread design and the Ideal Contour Shaping (ICS), developed for Diablo.

EPT technology brings to an innovative concept for the tread, a new dynamic profile design, supported by the patented zero degrees steel belt radial structure, new materials.

No compound at all would allow itself this level of performance: the key of grip is the entire tyre design. This is the reason why DIABLO ROSSO sets the new benchmark in Supersport tyres.
