CONCEPT and METHODOLOGY

Product concept Adding excellent wet performance to the best in class dry grip and handling feel in order to raise the ultimate hypersport possibilities to a higher level.

Focus on contact feel and cornering performance to always feel the connection to the road, in every aspect of riding.

Technical aims • • • •

Upgrade the wet grip/handling performance overall Increase handling lightness for additional sporty feel Increase the cornering speed No sacrifice on wear life

Methodology • • • •

Pattern design – linked to water drainage and block rigidity New tread structures in 3LC and 5LC New molecular approach for compounding Increase adhesion area in contact surface

PATTERN DESIGN

Front Pattern 1) Increase the Sea/Land ratio in the shoulder area 2) Optimize groove positioning and angle to create the right surface deformation 3) Groove design 3D edge shape for optimum rigidity

1 3

Rear Pattern 4) Increase the Sea/Land ratio in the shoulder area 5) Sharp 3D end groove for optimum rigidity 6) Optimize groove angle and alignment to redirect the working forces on the tyre
