A motorcycle tyre (1) includes a tread portion (2), a carcass (6), a breaker layer (7) disposed outside the carcass (6) with cords oriented at an angle equal to or more than 15 degrees with respect to a tyre (1) equator, and a tread rubber (10) disposed outside the breaker layer (7) so as to form a band-less structure in which the tread rubber (10) is arranged so as to be directly in contact with the breaker layer (7). The tread rubber (10) includes a cap rubber layer (11) forming a ground contacting surface (2A) of the tread portion (2), and a base rubber layer (12) disposed inside the cap rubber layer (11) and having complex modulus (E2) greater than that of the cap rubber layer (11). The base rubber layer (12) extends between a pair of outermost ends (12E) thereof so as to across the tyre (1) equator, and a thickness of the base rubber layer (12) at the tyre equator is greater than that of the outermost ends.
