A motorcycle tyre, comprising:

• a carcass structure;
• and
• a belt structure of zero-degree type arranged in a radially outer position with respect to the carcass structure;
• and
• a tread band arranged in a radially outer position with respect to the belt structure,
• wherein said belt structure comprises at least one reinforcing cord wound on said carcass structure according to adjacent coils oriented along a direction forming an angle ranging from 0° to 5° with respect to the circumferential direction, and
• wherein said at least one reinforcing cord has an elongation at break smaller than 2.45% and comprises:
• a plurality of first metal wires twisted so as to form a core of first metal wires;
• and
• a plurality of second metal wires twisted together around said core of first metal wires,
• wherein the number and diameter of said second metal wires are such that said second metal wires are not able to fully enclose said core of first metal wires,
• wherein the tyre has a curvature ratio greater than or equal to 0.2;
• and
• wherein, in each cross section of said at least one reinforcing cord, the second metal wires are positioned at only an angular portion of an ideal circumference that circumscribes the core.
