The rear tire has been redesigned for optimized pressure distribution and ground contact patch. The patented MICHELIN ACT + technology (MICHELIN Adaptive Casing Technology +) delivers consistent stability in line with the brand's Total Performance promise, straight forward as in the curve. The attributes that make up the sportiness of a motorcycle tire are grip, handling and especially the handling in alternating curves, hard acceleration and braking.
