Abstract
A tire for a two-wheeled motorized vehicle and more particularly a motorcycle includes at least one carcass-type reinforcement structure, formed of reinforcement elements, anchored one either side of the tire to a bead intended to be mounted on a rim seat. Each bead is extended radially towards the outside by a sidewall, the sidewalls meeting up radially towards the outside with a tread. Under the tread is a crown reinforcement structure including a layer of circumferential reinforcement elements. In accordance with the profile of the tire in a radial plane, the layer of circumferential elements is at least in part radially to the inside of the part of at least one carcass-type reinforcement structure radially to the outside of the two points of tangency of the curvilinear abscissa of the carcass-type reinforcement structure with perpendiculars to the axis of rotation, and the circumferential reinforcement elements are distributed in the transverse direction with a variable pitch.
