Motorcycles tyre, comprising: a radial carcass structure (2); a belt structure (6) applied in radially outer position with respect to the radial carcass structure (2); a tread band (8) applied in radially outer position with respect to the belt structure (6). The tyre (1) has a curvature ratio (f/C) greater than or equal to about 0.25. The tread band (8) comprises: a plurality of blocks (14) mutually spaced so as to define a tread pattern with a void/solid ratio (1−Sb/St) comprised between about 25% and about 50%; transverse grooves (11) placed in succession along the circumferential extension of the tyre (1) and each substantially extending over the entire axial width of the tread band (8). Each transverse groove (11) substantially extends along an axial direction. Two successive transverse grooves (11) circumferentially delimit an assembly (12) of blocks (14) placed in succession over the entire axial width of the tread band (8). Circumferential grooves (13) delimit the blocks (14) of an assembly (12). A ratio between a circumferential length (LI) of the blocks (14) and a width (L2) of the transverse grooves (11) is equal to or greater than about 2.
