Motorcycle tyre comprising an equatorial plane (X-X) and a tread band, wherein: - the tread band comprises a plurality of grooves suitable for defining a tread pattern; - the grooves of the tread pattern overall define a void-to-rubber ratio equal to or smaller than 15%, preferably equal to or smaller than 10%, on said tread band; - the tread band comprises a module repeated along a direction of circumferential development of the tyre, comprising: - at least one first pair of first grooves, oppositely inclined relative to the equatorial plane (X-X) of the tyre; - at least one second pair of second grooves, oppositely inclined relative to the equatorial plane (X-X) of the tyre; - the first pair of first grooves being arranged so as to circumferentially alternate with the second pair of second grooves; - the first grooves comprising, moving axially away from the equatorial plane (X-X) of the tyre at least a first, a second and a third substantially straight and substantially consecutive segments (21, 22, 23), wherein the first segment has an inclination relative to the equatorial plane (X-X) adapted to form an angle α equal to or smaller than 35°; - the second segment has an inclination adapted to form an angle α' equal to or greater than 90°; - the third segment has an inclination adapted to form an angle α" smaller than 90°, preferably equal to or smaller than 70°; - the first segment and the second segment extending in a radial region of the tread band defined by radial angles φ of between +/-5° and +/-25°; - the second grooves having an average inclination relative to the equatorial plane (X-X) forming an angle β equal to or smaller than 90°, substantially parallel to the inclination of said third segment of the first grooves; - the second grooves being arranged so that a continuation of their average inclination towards the equatorial plane (X-X) lies between a first segment of a first groove and the third segment of the first groove which is circumferentially adjacent. - the tread band comprises a plurality of grooves suitable for defining a tread pattern; - the grooves of the tread pattern overall define a void-to-rubber ratio equal to or smaller than 15%, preferably equal to or smaller than 10%, on said tread band; - the tread band comprises a module repeated along a direction of circumferential development of the tyre, comprising: - at least one first pair of first grooves, oppositely inclined relative to the equatorial plane (X-X) of the tyre; - at least one second pair of second grooves, oppositely inclined relative to the equatorial plane (X-X) of the tyre; - the first pair of first grooves being arranged so as to circumferentially alternate with the second pair of second grooves; - the first grooves comprising, moving axially away from the equatorial plane (X-X) of the tyre at least a first, a second and a third substantially straight and substantially consecutive segments (21, 22, 23), wherein the first segment has an inclination relative to the equatorial plane (X-X) adapted to form an angle α equal to or smaller than 35°; - the second segment has an inclination adapted to form an angle α' equal to or greater than 90°; - the third segment has an inclination adapted to form an angle α" smaller than 90°, preferably equal to or smaller than 70°; - the first segment and the second segment extending in a radial region of the tread band defined by radial angles φ of between +/-5° and +/-25°; - the second grooves having an average inclination relative to the equatorial plane (X-X) forming an angle β equal to or smaller than 90°, substantially parallel to the inclination of said third segment of the first grooves; - the second grooves being arranged so that a continuation of their average inclination towards the equatorial plane (X-X) lies between a first segment of a first groove and the third segment of the first groove which is circumferentially adjacent.
