Abstract
A motorcycle tire includes at least one carcass-type reinforcement structure formed of reinforcement elements, anchored on either side of the tire to a bead whose base is intended to be mounted on a rim seat, each bead being extended radially towards the outside by a sidewall. The sidewalls meet up radially towards the outside with a tread. Under the tread there is a crown reinforcement structure including at least one layer of reinforcement elements known as a working layer which has at least one continuous reinforcement cord forming portions in the central zone thereof. Those central cord portions display identical angles of between 10-80 degrees formed with the longitudinal direction, the angles being measured at points of intersection of the cord with a circumferential plane. Two adjacent cord portions are linked by a U-shaped loop.
