- Dry & Wet Handling - Equalized footprint pressure distribution during cornering is measured by optimally combining high-density Nylon Reinforced Belt and Steel Belt. - Dry & Wet Braking Performance - Improve brake force by appropriately combining the longitudinal stiffness of the pattern block with that of the footprint. - 3D wave & straight groove - The K107 outperforms the conventional by applying a wide straight groove on the outer edge and by maintaining the optimal footprint shape.
