Two different rubber compounds for the centre and the sides of the tread
Michelin Bi-Compound is a totally new mixture of two different rubber compounds in the same tyre!
In the centre of the tread, the rubber is more rigid for less straight line wear
On the sides, the rubber is softer and gives greater grip when cornering
Specific dual-compound tread, developed to ensure high wear resistance and yet grip when leaning the bike over.
The combination of the 110 TPI casing with the reinforcement from bead to bead ensure extreme resistance to perforations and cuts.
