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
