Abstract
A motorized two-wheeled vehicle, comprising a radial carcass reinforcement formed of at least two layers of reinforcing elements, and comprising underneath the tread a crown reinforcement structure comprising of at least one layer of reinforcing elements. At least the tread surface comprises a first polymeric compound extending in at least the region of the equatorial plane and at least one second polymeric compound having physicochemical properties different from those of said first polymeric compound, the density of reinforcing elements in the radially inner carcass reinforcement layer being less than that in the radially outer carcass reinforcement layer.
