A motorcycle tyre includes a tread band divided into a central zone and two shoulder zones. The central zone extends symmetrically on either side of the equatorial plane of the tyre over a width less than or equal to 60% of the lateral extension of the tread band and has in the central zone at least one first module repeatedly duplicated in a direction of circumferential extension of the tyre including: at least two longitudinal grooves inclined relative to the equatorial plane; and at least two substantially transverse grooves intersecting the two longitudinal grooves so as to define at least one block. The central zone further has a solids/voids ratio greater than the solids/voids ratio of the shoulder portions. The tread pattern has at least one circumferentially continuous rib situated in an axially outer portion of the shoulder portions.
