• Front tyre: the smaller crown profile gives a longer contact patch and better pressure distribution for improved handling and precision.Rear tyre: the larger crown profile together with optimized belt construction and groove positioning upgrades rear feeling and increases cornering stability.
• Rear tyre: the larger crown profile together with optimized belt construction and groove positioning upgrades rear feeling and increases cornering stability.
• 3-layer compound (front) and 5-layer compound (rear) plus high-stiffness bead filers give optimum damping and stability.
• Pattern with 3D groove ends, optimized groove layout and almost-slick shoulders designed for stability and handling with consistent high grip.
