Abstract

A motorcycle tyre, comprising a radial carcass structure () and a tread band () applied at a radially outer position with respect to the radial carcass structure (), wherein the radial carcass structure () comprises a first carcass ply () and a second carcass ply () including a first plurality of textile reinforcing cords () and a second plurality of textile reinforcing cords (), respectively, wherein the first textile reinforcing cords () are parallel to each other and the second textile reinforcing cords () are parallel to each other and have a respective first and second inclination at a crown portion () of the tread band () with respect to an equatorial plane (X-X) of the tyre, wherein said second inclination is opposite to said first inclination. The first textile reinforcing cords () and the second textile reinforcing cords () have a tenacity comprised between 0.35 cN/Tex andcN/Tex at 2% elongation and comprised between 0.5 cN/Tex and 3 cN/Tex at 5% elongation. At least one central annular sector () of the tread band () arranged astride of the equatorial plane (X-X) is made of a vulcanized elastomeric material having a static elastic modulus Ca3 measured at 70° C. comprised between 9.0 and 14.0, a tandelta measured at 70° C. and 10 Hz comprised between 0.120 and 0.160, and a dynamic elastic modulus F measured at 70° C. and 10 Hz comprised between 3.7 and 4.1.
