A motorcycle tyre includes a tread rubber that includes a base rubber layer and a cap rubber layer disposed outward in the tyre radial direction of the base rubber layer to form a ground contact surface. The cap rubber layer includes a crown cap portion disposed in a middle region in the tyre axial direction of a tread portion and a pair of shoulder cap portions disposed in both sides in the tyre axial direction of the crown cap portion. The crown cap portion has a loss tangent tan δc, the shoulder cap portions have a loss tangent tan δs, and the base rubber layer has a loss tangent tan δb, wherein the loss tangents tan δc, tan δs and tan δb satisfy the following equation (1): tan δc < tan δs ≤ tan δb ···(1).
